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.
