At first glance everything appear drab and colourless at this time of year. Admittedly the spring planters at the shop are pleasing this year, with their new crocuses and tete-a-tete daffodils, but generally things appear lifeless….Until you look closer and then some startling colours stand out.
I’m running around spotting the new sign of life and noticing all the things I need to be getting on with. Spring is springing, the days are getting longer and we’ve had a nice spell of weather that looks like (barring an overnight storm) continuing into next week. I’ve been trying out an app (gardenwize) to try and keep better records this year (one of my NY resolutions) but it doesn’t look like it will do quite what I want it to do (although about the best that I found). I think I will have to go back to hardcopy and get myself some index cards and just write a new card for each crop. It’s either that or write my own database, and I always get on better with spreadsheets. At least I won’t have to worry about back up.
I have already managed to sow some of my polytunnel plants in the propagator: the achocha, tomatoes and a chilli pepper. Some of the tomato seeds and the achocha are already sprouting after less than a week. I’ve also got some shrubby seeds that have been stratifying in the fridge for several weeks or months, which mostly may as well be planted out now into seed trays. Then it’s more sowing and potting on ad infinitum!
Plants are definately feeling the spring now. The tree buds are starting to swell, pig nut leaves are out and the first celandine flowers are showing. I must get down the hill and coppice some of the larger alder before the sap risies too much. I’ve got a bit of persuading S. that some of the trees would be better cut at this age. Admittedly it will be a pity to lose some of the shelter that has been achieved, but the trees should grow even better if fully cut back, since all their roots are sized to feed a whole tree.
Other wildlife is also feeling the changing times. There were a couple of lumps of frogspawn down in the pond. I haven’t seen the frogs there. It may be a little early yet, but I expect most of the spawn would survive a light frost anyhow. Hopefully we won’t get a hard frost anyhow because look what I’ve got in the poytunnel:
The Apricot buds are blossom. There is actually a lot more than I thought there would be: it is also all up the main branches. Most of the buds are tightly furled, but they are just beginning to open. I used a tiny bit of cotton wool to dab the flowers. They seem quite scented, so if any of the moths whose pesky caterpillars were eating it last year are about, they may fancy pollenising it for me.
I took a whole lot of elder cuttings since the bush has done so well for me. I have also got some cuttings off three other bushes: One local, one imported like mine, and one purple leaved bush. Some of the cuttings are in the orchard area which I tried to put down to green manures last September. The area now has a fair covering of bittercress and grass. Pictured above is one of the two field beans that seem to have escaped the crows’ attentions.
The other major project that I am hoping to get finished in the next week or so is the driveway retaining wall. I spent yesterday afternoon scavenging round for rocks, since I had pretty much exhausted the initial supply. Where the spade is in the picture above is where I plan to make a pedestrian access to the bank above. I’m not sure whether it will be a ramp or steps – probably steps, since it would be too steep for a barrow anyway, and I can also get to it from the garden to the left. I had to dig out half a big fuchsia bush that would otherwise be a nuisance growing across the path there. That took me most of today, but I have three big lumps of bush as well as lots of sticks to make cuttings from if I want. I think I will propagate some, since the fuchsia is tough as old boots (that bank is quite exposed to the south so gets quite a bit of wind as well as sunshine) but when in flower looks quite pretty. This one has pale pink flowers rather than the darker pink that is more common as hedging plants around here. It sets less fruit, probably due to the exposed position.
Winter has finally arrived, we have a little snow that has stuck around for a few days, gradually refreezing as ice as it is trampled and melts a little during the day. I quite like a bit of quiet time to look around and see the structure of the ground under the plants. You can see the pathways made by people and dogs as the slightly flattened grass remains whiter with snow than rougher areas.
I have done a little pruning, although you are not supposed to do this when it is frosty! The remaining gooseberries in the fruit garden didn’t take long, and I have cut down the sapling sycamore tree that would have crowded one of the apple trees there. It may grow back, but I can just prune it out each year for pea sticks until it gives up! The apple that I grafted before I came to Skye and that was living in a pot for a while has unfortunately grown a little one sided. I assume it is just the prevailing wind that has achieved this, and am not sure if it is possible to reverse….
With the freezing weather there is little plant wise to do outside, but I have been able to get a little done in the polytunnel. As threatened I have drastically pruned back the kiwi vine. As well as shortening it, I have also taken out some of the larger fruiting side branches. This should encourage new ones to grow and be more fruitful. I tied the main trunk a little tighter to the overhead wires, as it was hanging a little low and even interfering with my headroom. The grapevines are far simpler to prune. I simply cut back all the side branches close to the main trunk.
I am very hopeful that what I am seeing here is flower buds on my apricot. I’m still not really sure whether I’m doing the right thing with the pruning of this. I think I now need to cut back the main branches by one third to an upward facing bud and tie in new branches in between the existing ones, and then I’m into ‘maintenance pruning’ whatever that means! I know I’m not supposed to prune when the plant is dormant so I need to leave it a couple of months.
There is a little weeding to do, and I also need to start watering a bit more in the tunnel as well in preparation for some early sowing. I think the akebia is surviving nicely, but I’m not sure about the passionflowers. I think they were a bit small and I should have brought them into the house last autumn. The propagation area keeps expanding. I could really use more space for putting the growing on plants. I’ll have to have a think about this. Maybe I just need to tidy up a bit more efficiently! Theoretically there is lots of space on my little greenhouse frame, so perhaps I’ll just concentrate on getting that properly sorted again. It just keeps filling up with empty pots!
Being as the year is just about over, it seems appropriate to have a little look back at this point in time.
I haven’t written about some of the trivia that I’ve been doing more recently at home, partly because much of it is unfinished yet, and partly to catch up with my holiday garden visits. Over all we have been pleased with the way the trees have grown this year. S. managed to pick a nice tree to bring in and decorate this Xmas. It’s getting a little more difficult to find a spruce tree that is small enough and isn’t being an important part of a windbreak.
The ash and alder as usual, along with the spruce, have grown well. You can also see how the trees with a little more shelter grow a bit better. Even some of the hazel is growing a bit better in places. I’m a bit worried about the ash however. Although it grew well again this summer, as we saw, as usual there is quite a bit of die back. This time the bark staining seems to match the characteristics of chalera. I had a look online at the woodland trust and forestry commission sites and the way the staining goes up and down from the leaf buds does seem to match chalera, however, there is no internal staining of the wood when I split it down the middle. I’ll send the pictures off to the woodland trust. These ash trees were ones they helped us buy, so they should be able to give us some advice about it.
I have grown a few new unusual edibles for the first time. Oca, wapato (sagittaria latifolia), marsh woundwort (although I also found this growing natively in the tree field I think) and edible lupin. This last was part of Garden Organic members’ experiment. In summary I’d have been better off eating the lupin seeds they sent rather than planting them. I’ll do a brief post about them separately however.
I’ve managed to grow some new perennials from seed, now I just need to get them through the winter. Some of them came from the Hardy Plant Society seed distribution list, and some were bought from various suppliers. I have a number of cornus kousa, a couple of canna indica, several akebia triloba, two different passiflora, broom, watercress, astragalus crassicarpus, a couple of campanula varieties and dahlia coccinia. A few others germinated and perished including gevuina avellana (second time of trying) and hosta. Many more seeds also never managed to germinate for me. I have quite a few little plants waiting for their “forever home”. One korean pine is still alive, but very small. A saltbush plant is doing quite well in a pot, but I’m not sure if its atriplex halimus or a. canescens.
Crop wise I grew physalis peruviana for the first time on Skye. I seem to remember growing it in Solihull and not being particularly impressed. Here in the polytunnel it has grown quite huge and is still alive at the end of December, although with a little mildew. It could grow as a perennial if it isn’t too cold, which was one reason I gave it a go. The berries are nowhere near ripe however. Along with many of the things that needed potting on and watering it got a bit neglected due to the super hot early summer. I don’t think it was a fair trial therefore, since it didn’t get an early start. The plants have grown huge compared to the fruits produced. I seem to remember reading that this can be due to good nitrogen content of the soil (producing lush foliage and little fruit) however this does seem unlikely for me!
Another plant that got a slow start, but made good growth is tomatillo. These were so stunted when I planted the few survivors out that I nearly didn’t bother. Once in the ground they grew away fine. I’ll have to check how they are doing now.
The tomatoes managed to ripen a few delicious fruit before I had to harvest them due to mildew on the vines. The supersweet 100 was earliest and quite prolific. The first in the field wasn’t but did pretty well for a standard salad tomato. I like it because it is a bush variety, and it stayed quite compact. This makes it easier to grow close to the edges of the tunnel. Spread out on the window sill we did get a few more fruit to ripen, but many just went mildewy there.
Achocha needs to go in earlier. I couldn’t resist ordering the giant bolivian variety from real seeds again this year even though I know it really struggles to get going for me! This year I didn’t get any fruit before the plants got killed by the frost! S. doesn’t really like globe artichoke. He finds it a bit of a fiddle to eat. This is a pity, since I have managed to get a few more plants of a known variety to germinate and hopefully get them through the winter. I will try one more in the tunnel and the others outside anyhow. I want to try eating the cardoon stalks next year. It is a case of remembering to tie them up to blanch at the appropriate time.
I’m fairly pleased with the way the apricot is growing: a bit more quickly than I was expecting. I’m hoping I may get a few blossom this spring with any luck! Still got a bit more formative pruning to do, but it’s looking good so far, as long as it stays small enough for the tunnel! The boskoop glory grapevine did well. I didn’t manage to harvest all the grapes before they started to go mouldy. The autumn was a bit cool and windy, although not unusually so I would say. The new Zalagyongye vine started to set the single bunch very late and they stayed very small, although were quite sweet. Hopefully it will do better as it gets older.
I’m wondering whether to give up on the kiwi vine. I picked the fruit a week or so ago, they were starting to drop off the vine, but still don’t seem very sweet. Judging by the grape, it hasn’t been a good year for ripening, but considering the size of the vine and the use we get of the harvest (there are more pleasant jams to make) I’m not sure it’s worth the space it takes. S. wasn’t keen on getting rid of it because it is a lovely big plant. It does also produce a huge amount of large leaves which have dropped off and formed a mulch layer in the tunnel which is nice. I’ll need to rake them off the paths though. Since S. spoke up for it I’ll prune it back a bit, give it one more season and then we’ll see. If I do take it out I was thinking of replacing it further up the tunnel with a kiwi-berry actinidia arguta, or kolomitkes. These have smaller, hairless berries that ripen earlier, so are likely to be more successful for me. The plant is also a little less vigorous, so takes less pruning.
I have two pineapple guava at the bottom end of the tunnel. These have not flowered yet, but are growing well. I have been nipping out the longer shoots to encourage the plants to grow bushily. This will stop them getting too big too soon and also maybe more dense flowering if and when that happens. I don’t know whether they will ripen fruit for me. They need a hot summer to ripen. However the flowers are supposed also to be delicious, so I would be happy to settle for those!
A number of strawberries fruited in the tunnel. I had them from two different sources, and I can’t remember now which is which! I did get a few very delicious berries, but struggled to keep them watered and lost a few plants. I have managed to pot up a number of runners from one of the successful plants, so can move those into some of the gaps. I also have a number of different strawberries outside some of which managed to ripen a few berries, but need a big of feed and weeding really.
Still in the tunnel the asparagus is starting to look promising. It is still shooting up spears now however! I’m hoping that next year I can try and harvest a few shoots, so watch this space. Another success has been the milk vetch which I grew from seed. In one of Martin Crawford’s books he suggests it as a non competitive perennial ground cover with shallow roots. I’ve planted it in various places around the tunnel. I’m hoping it will cover the ground around the asparagus plants, since they don’t like competition from weeds. If they managed to fix a bit of nitrogen that also wouldn’t be bad!
The sweet potato harvest was rather small. I think I didn’t manage to water the plants enough. They were lovely big plants when they went in. I’m wondering whether they were actually a bit too big. One of them had rather more tubers than the other, but they were all a bit tangled up, as if the plant had been a bit pot bound and never really developed tubers beyond the roots already started. The other had longer roots, but several only just starting to thicken. Either it had been cut back by the cold too early, or it just didn’t grow quickly enough. Unfortunately, I don’t think either of these plants or tubers are likely to survive the winter. I’ll give it a go however, since it will be silly to fork out that value again. If I can plant them out earlier, and feed and water them better, they may stand a better chance….
Somewhere near the sweet potato are two dahlias. These were dahlia coccinia. I grew them from seed from the HPS list, and they have attractive burgundy foliage and pretty red single flowers. I didn’t try eating the petals of these, although they should be edible along with the tubers. I have a couple more that grew and flowered in pots. These need to be moved somewhere frost free over the winter so they don’t rot. I’ll try and post about harvest another time when I’ve tried them. Apparently the taste and texture is variable….
The climbing nasturtiums were a little slow to get started. I think they got a little dry in the hot earlier summer. Once things cooled down there were a couple that did very well, including one growing through the apricot that hasn’t got killed by the frosts yet. The one opposite this had the most beautiful tiger red flowers however. I’ll try and get seeds from this! I’m not keen on eating them, although I believe all parts are edible, but I do like the flowers. I also like the way outside that the circular leaves catch rainwater and form droplets.
The unknown citrus is still looking quite green. While it is still mild I will wrap it in some fleece to try and protect it a bit this year. Unless it has some established branches it will never flower and we won’t find out what variety of fruit it has.
The polytunnel pond has held water which is a good start considering I had to repair the liner before using it! I grew watercress, marsh woundwort and sagitaria latifolia in pots in it. The watercress has escaped from its pot and seems to be mainly floating round on the surface. I think it will die back overwinter, so am not sure whether it will return or not. The pond was also very useful as a means of soaking seeds trays and watering from the bottom. I’m very glad I designed some very shallow shelves around the edges, as well as much deeper ones! It was certainly welcomed by Mr. Toad, and although there were insect larvae and algae it never got stagnant or a noticable source of pests. Midges breed on damp vegetation of which there is plenty outside, so it didn’t contribute to those Scottish pests either!
Having seen Sagara’s successful olive fruit, I have to conclude that none of my olive flowers did set fruit. The plant itself looks pretty healthy though. It has grown a bit and bushed out. I’m hoping it will overwinter alright in the ground in the tunnel, since the soil in there should be fairly dry and it is protected fully from the wind. Fingers crossed for more flowers next year. I have read that olives fruit better with cross fertilisation, so maybe I should look out for another variety. I’m not quite sure where I would plant it though!
Since I only got one surviving five flavour berry, I have obtained another two plants from two different suppliers. They are both supposed to be self fertile, but should also fertilise each other, and the surviving seedling. Both are planted out in the tunnel and mulched now for the winter. The passionflower and akebia were still very tiny plants as we went into the winter, so I’m not sure they will survive. I’ll try and remember to bring some into the house to overwinter as insurance if I can find the spare plants!
The yacon grew quite huge in the tunnel, at least above ground. It has pretty well died back now, but the oca is still green in there, so I may leave digging both until the oca has finished its stuff. I had not split the Yacon plants which I think did give them a better start this year. I think I will maybe try and propagate a few more plants for outside growing, but generally leave the inside plants as undisturbed as is compatible with digging up the edible tubers! The oca and Yacon outside have been harvested (I’ll write about that together). The oca seemed to be doing better outside, but died back more quickly. The Yacon outside seemed a lot smaller: we’ll see what the harvest is like!
I’m reasonably pleased with the landscaping I achieved in the tea garden extension and orchard area. I need to carry on eliminating perennial weeds (couch grass particularly) and get on with ground cover planting. I’m also putting up some windbreaks in the tea garden extension, thanks to our new grocery supplier at the shop, who make their delivery on a pallet. I was particulary pleased to recieve a scarlet pallet! Next year I also want to do a bit more work in the fruit garden to change the path layout, and maybe get rid of the autumn fruiting raspberries, which are really too late to be worth the effort. I also have started a retaining wall along the driveway. This gives me a nice south facing well drained site. I need to get a good windbreak planting along the top. I have some escallonia cuttings coming on nicely, which I know do very well here. These have nice raspberry pink flowers. Although the plant is not edible, it is tough, quick growing, evergreen and attractive, which I think will be enough in this location.
I’m definitely looking forwards to 2019 and all the exciting things growing next year.
So much to do so little time! Summertime is here, the daylight and the shop hours are longer…We seemed to skip straight from winter into summer here – usually spring is the nicest time on Skye, drier weather, (often warmest too!) no midgies and fewer tourists (we love them really!) I’ve been helped on my family research by my younger sisters and my mum coming for their holiday on Skye last week. A folder of old family documents and letters shed some fascinating insights into some of the Kent branches of the family. A few seem to have been soldiers and I’ve scanned in some of the documents to transcribe. One letter is from a soldier in Madras, India in 1832 describing the effects of a cholera outbreak and urging his brothers and sisters to stay home and not be tempted abroad. I haven’t placed him yet on the family tree, but he does seem to have survived to a ripe old age despite obviously in fear of his life at the time of his writing.
I thought I’d just review the winter and what has done well or poorly this year. Amongst my losses are my rock samphire plant (grown from seed – first winter), my sea beet (both an established plant that flowered last year but did not set seed and all of my seedlings in pots), some of my Camellia sinensis plants (small plants in the fruit garden – the ones in the tea garden are thriving), the unknown citrus in the polytunnel, my baby yacon seedlings, and a Luma apiculata that never made it out of it’s pot. Considering how cold the winter has been, not so much in intensity as in length, it could have been a lot worse.
A surprising survivor is a mashua plant that appears to have grown from a missed tuber in the fruit garden. I suppose since it can be grown as an ornamental perennial (think Ken Aslet) It shouldn’t be that surprising. I will leave this one and see how it does. I haven’t in the end planted any more mashua outside this year.
The apricot is doing well – I have now trained in seven shoots as described earlier, and they are needing tying in again. Unfortunately I did get one of the shoots slightly wrong – pinched out too many earlier on and was left with one that was growing at the wrong angle. I’m hoping it will straighten out as the plant grows.
I have grown a number of plants from seed this winter including what turned out to be Akebia triloba. This was grown from seed obtained via the facebook edimentals group from someone who ate the fruit in Japan, but we weren’t sure until the leaves appeared whether it was A. quinata or A. triloba. It should be hardy outside here, but will probably do better in the polytunnel. If the plants survive I’ll try both. I have also grown some passion fruit vines (still very tiny) Passiflora edulis and P. mollissima (I think). Some of my other seedlings have struggled in the hot weather we had a couple of weeks ago – the pots dried up very quickly and the tiny plants may not have made it. I had some martagon lily that I think have gone now, and some of my vetch seedlings have also gone. These include, annoyingly, the Astragalus crassicarpus (gound plum) that I was looking forwards to establishing in the tunnel. Luckily the single chilean hazelnut that germinated seems to be doing alright, and is now showing signs of sending up a second pair of leaves. This is better than the seeding I achieved last year which faded out at a single pair.
I was busy outside trying to get on top of the creeping buttercup before it took over everywhere again, but got distracted moving more soil down the hill to landscape the orchard area. This is nearly achieved, but more work to do on the south side of the trackway. Just at the moment the buttercups in the field are making a fine display with the pignuts, and remind me that we’d be poorer if we succeeded in eliminating weeds!
We continue to have a snowy winter. Showers interspersed with milder days so sometimes it’s icy and underneath the soil is sopping wet. Down the northern edge of the tree field the dogs have made a cut through path to the pond at the bottom. I sometimes use it to go down that way, and sometimes go the longer way around the main rides. Since the dogs don’t pay too much attention to where the baby trees are, some are rather close to the path.
Last year I moved an oak that was right in the path. S. mowed along the path in the summer and it was tricky to zigzag between all the trees. I therefore moved three trees to improve the line of the path and make it easier to mow should we choose to do that again. There were two birch and one hazel that were definitely in the way and I moved them to the lower windbreak line, which does still seem to have a few gaps in. I have also been given a number of lodge pole pine seedlings (thanks again Frances) and those have been safely planted, some near the byre at the top, and some down in one of the lower windbreaks.
The other things I have been doing are mainly in the polytunnel. This week I got round to pruning the apricot for it’s second year training. Again this was a rather brutal procedure, cutting both main arms down to a length of about 12 inches.
I need to be alert to how to train it during the summer growing seasons now, since this will be the last dormant pruning. From the rhs website:
“In summer, choose four shoots from each ‘arm’: one at the tip to extend the existing ‘arm’, two spaced equally on the upper side and one on the lower side. Tie them in at about 30 degrees to the main ‘arm’ so they are evenly spaced apart (using canes attached to the wires if necessary)
Rub out any shoots growing towards the wall and pinch back any others to one leaf”
Not that I’m growing on a wall, but the principle will be the same I’m sure.
The other very exciting thing that I’ve been doing in the tunnel is creating the pond, that I’ve been wanting for a while. I had some remnants of pond liner from when my mum had a large pond made in her previous house. Unfortunately during storage both sheets have been slightly damaged by mice making nests, and I didn’t think either would be quite big enough for a pond approximately 6 feet by 5 feet and 2 feet deep. The first step therefore was to mend the holes and extend the best liner so as to make it big enough. While that was curing, the hole for the pond was finished off, with shelves at various depths around the edges. I had some more bits of automotive carpet underlay which I lay mainly on the shelves and the base to protect the liner from stones in the soil. Luckily the liner extension wasn’t needed in the end – the slope of the sides meant it wasn’t quite as deep as I’d calculated – just as well, since it was impossible to stop the liner creasing at the joint, so it would have leaked anyhow! I used the wooden terrace side as one side of the pond, and another plank as a hard edge to access the pond on the opposite side. Filled with water and edged with flat stones, the pond is now settling in nicely. The few plants I’ve got so far (tigernut and sagitaria latifolia) are dormant in tiny pots at the moment, so I’ve made a very shallow shelf that they can just sit on in just a little water, as well as deeper shelves for bigger marginal plants in the future. I’m hoping to get some other plants, and of course watercress may well be worth a try, although I’m not sure that we’d use very much.
While I was in the polytunnel, I took the opportunity to tidy up a bit on the rhs as you look downhill: levelling out the soil (some of which had been heaped up from digging out the pond). I also managed to clear out a load of couch grass that had grown in the bottom corner of the tunnel near the kiwi and bramble plants. In fact it is growing around the kiwi root, and I expect it will come back again this year. It also is able to punch it’s way through the plastic walls of the tunnel. I’ll have to keep an eye out and keep knocking it back. Since I choose not to use poisons it will be impossible to eliminate in this situation. Anyway, half the tunnel us now clear and weeded. I need to start watering it a bit, it has got very dry particularly on the surface. Once it is damp again, I expect that some of the seeds will regrow – there are some nice claytonia seeds in there that prefers cooler temperatures so grows better in the tunnel in the winter.
I’ll write a post soon about the mashua and yacon harvests in the tunnel.
I blame Martin Crawford! I’ve got over excited again planning new plants for next year already. I know it’s too early, but I recieved an e-mail from the Agroforestry Research Trust saying that they are open for plant orders. I need to try and remember whether I’ve got some plants reserved. I think I wanted Toona sinensis (a tree that grows onion flavoured leaves) but they had run out last year. I know that I fancied some Stachys palustris – marsh woundwort. Since there was an article in agroforestry news about it, I expect I won’t be alone.
What I’m really getting excited about at the moment is the idea of growing more perennial plants in the polytunnel. I’ve got on quite well with the fruiting vines. I have a kiwi (Jenny SF) and a bramble (unknown) which came with the kiwi. I was growing the kiwi in Solihull and it was one of the few plants I brought with us. When planted in the tunnel the bramble grew too. I tried digging it out several times, but it kept growing back, so the third year I left it, trained it along some overhead wires and was astounded by the fruit it produced. They are lush and sweet-tart, just like blackberries should be, but are also of a good size. The vine is not thornless unfortunately, which makes for an anti-social plant in a confined space. The roots I dug out, have fruited outside in a good summer. They may do better with a bit more shelter as well, since the local brambles have so far been pretty similar in timing for me (but much smaller). I also have a grapevine – boskoops glory, which I grew from a cutting of the vine I had on the veranda in Solihull. I don’t think it would crop to any extent outside here, unlike in Solihull, but is doing pretty well in the tunnel. I have a white grape vine also, which has yet to fruit for me. It seems to be growing well this year, so maybe next year I might get some fruit. I have also planted a couple of pineapple guava: Feijoa Sellowiana. As well as the reputed delicious fruit, which need a hot summer to ripen hence the polytunnel positioning, they also have edible flowers. I’ve not been able to try them yet, but they seem to be establishing OK near the lower doors in the tunnel.
In the polytunnel when we moved in was a globe artichoke, which has produced some lovely flowers/buds. It hasn’t done so well this year. I did divide it this spring, so it may be that it is suffering from the damage and will take a while to recover, although being eaten by several hungry caterpillars probably isn’t helping! The offsets I planted outside in the fruit garden and at least two of them seem to be growing away quite well so far – we’ll see whether they survive overwinter. Also in the tunnel was an olive tree in a tub. I neglected it and thought it had died of drought, but when moved outside, it sprouted again from the base. I thought it was a privet seedling at first, and only realised the olive was alive when I tried to dig it out of the tub. Anyway, although planted in the tunnel soil this spring, I think that the tree is finally dead now. There are also a couple of marjoram plants as well, which I cut for leaves every now and then and seem to tolerate my neglect remarkably well. An aloe vera which had been on the window sill in the house, gradually getting taller and taller, is now also in the tunnel – not sure whether it will survive the winter however.
This year I planted my new apricot, which is doing well so far, and some kind of citrus, which was given to me as a rather spindly plant needing a good home. It has been grown from seed, and we are not sure what kind of citrus it is – will have to wait til it flowers!
I quite enjoy this kind of structure in the polytunnel, and outside come to that. I am very keen on plants that provide me with food year after year with only a little attention. Annual plants are far too liable to succumb to juvenile death due to overcrowding, slugs or lack of germination. So having been started off by Martin Crawford, I have been going through my various lists, books and getting distracted on the internet to try and come up with more perennials that will benefit from the shelter of the tunnel, and yet survive the winter and create a food forest. So far I’ve deselected again tree tomato / tamarillo: solanum betacea, pepino: solanum muricatum, Taro: colocasia esculenta var. esculenta and Eddoe: c. Esculenta var. antiquorum as being just too tender, although they all sound fascinating. I don’t (at the moment anyway) want something that will need moving indoors during the winter, and although we don’t generally get hard frosts we do get frosts that would penetrate the polytunnel’s protection.
So on my list of perennials to grow in the polytunnel are (in no particular order):
Kiwi (got – but might like a kiwi berry – one of the small hairless ones)
Apios Americana (got – maybe if it survives the slugs this year)
Chinese yam: Dioscorea batatas (got – ditto re. slugs!)
Globe artichoke (got – but might fancy a different variety)
Chilli (got – survived one year on windowsill)
Passionfruit (need to source)
Ground plum: astragalus crassicarpus (need to source)
Aloe vera (got)
Runner beans (got – growing some heritage seeds library ones. I guess a few different ones would be required to see which over winter the best)
Fuchsia (got – fuchsia berry from my mum currently in a pot in the tunnel looking for a home)
Five flavour berry: Schisandra chinensis (got – but only one of the three plants seems to have survived, and you need a male + female for berries)
Korean mint (got – seedlings from a neighbour)
Sage (need to source)
Rosemary (need to source)
Licorice (need to source)
Blue sausage fruit: Decaisnea fargesii (need to source)
Honey berry: Lonicera caerulea (need to source)
This is not a timely post. I just thought I’d catch up with one of the new exciting plants I’ve got new this year. I’d fancied an Apricot for a long time. Although they probably would grow outside here if you had enough shelter, I’m still a long way away from that. However, I am growing more and more perennial plants in the polytunnel, so I thought I’d like to try it in there.
The plant was a present – a one year grafted whip of Early Moorpark Apricot on Torinel rootstock and was a good height, perhaps 4 feet tall. The first hard thing I had to do on planting it back in February was to cut it right down to about 1 foot tall! This is the exception to the general rule about pruning stone fruit only in summer to avoid silverleaf infection. According to the RHS “Apricots bear fruit on shoots made the previous summer and on short spurs from the older wood” and unless growing as a bush (which I thought would be impractical in the polytunnel) should be grown as fans. I rather fancied an espalier, but again that wouldn’t work for an Apricot. I found the RHS website very helpful in giving directions for training from scratch. So I planted, cut back and watered, and waited, hoping I hadn’t killed my lovely tree!
Sure enough, as promised, several new branches grew strongly from the trunk, which was a bit of a relief – I hadn’t killed it. The next step for me, was to put up some training wires. A little less straightforwards for a free standing fan, since I had no wall to come off. The arch of the polytunnel also meant that I couldn’t put in two vertical posts and string the wire between. I ended up using some random bits of wood we had lying around to create the framework. I had one nice vertical fence post by the centre path in the polytunnel, and one sloping bit as far to the side as I could manage. Since neither was in deep enough to take much strain, I have braced them with horizontal bits of wood before putting across the neccessary horizontal straining wires.
Then came another hard part. Again I had to cut back my lovely tree. This time the object is to select two branches to train in a 90 degree ‘V’ shape. I actually left two on the out board side since I couldn’t decide between them. Since then however, one has lost it’s leading point, so I think the decision has been made for me and I now need to prune that one out.
So far I am very happy with the health of my tree. It has grown well and has had no signs of any problems at all. Since it is undercover I need to keep an eye out for pests. Spidermite may become a problem. I have had this in the past on other plants in the tunnel and it really does stunt the growth. Also the soil I have is not very deep, generally less that two feet and usually less than that. I can’t do much about that. Since the polytunnel is slightly terraced (it slopes from end to end) I have put the Apricot in the downhill bed where the soil is slightly deeper, and I have been careful to water well but seldom, to encourage deep root formation if possible. Next year in the early spring, I will need to bite the bullet again and cut the leaders back again to encourage further branching to create more of the fan structure. I wonder whether I will get any blossom? Very exciting!
