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!
