Having decided that the Kiwi vine wasn’t worth the space and the daylight it took in the Polytunnel, I spent a few wet afternoons in January and February digging it out. Since it was pretty much in the corner I had to be careful of the polytunnel sides when digging. I wasn’t certain when I started whether I was taking the bramble out as well. Actually I rather though I would be digging that out too, despite the great crop of sweet early brambles it usually gives. However in the event, it really was too close to the polytunnel corner to take out. Also it seems to be quite separate to the kiwi root mass so didn’t naturally come out at the same time.
Although I tried hard to take up as much root as possible, the kiwi roots are surprisingly fragile, so most of them got broken quite short during the excavation. Eventually the last roots going out under the tunnel wall were cut through and the rootball was undercut and freed. It was interesting that most of the larger roots were extending into the tunnel rather than out into the damper soil outside the tunnel. I think this indicates that the kiwi will prefer drier soil. That corner of the tunnel outside however, is also particularly wet, since there is a shallow drainage ditch I dug along there quite early on, which doesn’t yet have a destination except just by the corner of the tunnel. It usually fills with water there after any significant rain.
I had decided to plant the kiwi against the largest of the sycamores in the front garden. I don’t expect it to be quite as vigorous outside as it is in the warmth of the tunnel. It may not like the extra wet as well as the cooler temperatures. However I remember seeing kiwis swamping a tree in the Fern’s field, so don’t want to plant it somewhere where the trees are still establishing. In addition, it will be more difficult to prune the vine in a tree so I’m actually intending to let it run free as much as possible. This means that I may not get so many flowers, but since I am not expecting to get any fruit outside it doesn’t really matter.
I started by working out roughly where the kiwi was going to be planted; a little way from the tree trunk. It means that there will not be a way around between the tree and the road above the barn. However, there wasn’t before either due to the way the soil has been heaped up, and the clump of branches growing from the bole of the tree. I managed to get the kiwi up the drive bank and in position, with a bit of a struggle. I loosened the soil where it was to go, and dug just a little bit out, since I needed to adjust the soil levels to a bit higher there to blend them in more. I didn’t give the kiwi any extra compost; I’m expecting it, if it survives, to be quite vigorous enough already! Having backfilled the hole to level, I lifted soil from adjacent to the barn roadway to smooth out and level the area between the kiwi and the drivebank. There is quite a bit of nettles well established there. Although I pulled out quite a bit of root, there is plenty more undisturbed there still. I threw those roots I did pull out between the kiwi tree and the barn roadway. There will be a little shaded wild spot where I don’t mind the nettles staying. There were a few dock roots and couchgrass too, which will probably persist.
Luckily over the past few months I have built up quite a reserve of sheet cardboard, so was easily able to mulch the whole area pretty thoroughly. I weighed the sheets down with rocks that had been used to weigh down the cardboard at the top of the drivebank last year. That cardboard is pretty much gone, and the soil underneath looks pretty weed free. I’m now thinking about planting this area in the next few months. What I found pretty exciting is that the soil I was moving from the edge of the barn driveway was pretty dry. Despite the fact that this January was the second wettest month locally for about ten years. I can therefore think about planting things that prefer to be well drained. I’ve got several plants growing nicely already (for example those japanese and chilean plum yew may like it there) but also I’m thinking that along the drivebank edge may be just the spot for some sea buckthorne. I’ve really fancied this shrub for ages, especially after trying the fruit in Cornwall and Devon. My research so far suggests it doesn’t like a damp soil, but should be OK with salt winds, although fruiting better with some shelter. I’m intending to get some general hedging plants, but will maybe get some fruiting cultivars too. I’m not sure whether I should get these at the same time, or instead, or try out the cheaper varieties before spending a lot on something that doesn’t do well. Difficult decisions!
