I currently have 6 apple ‘trees’ & 4 sapling crab apples. I have 2 in the ground - the one I re-positioned and another that is just along from the bower seat.
The apples in the pots & vigoroot bags do better than either of the pair in the ground. The one that consistently is doing the best is the Bramley Seedling.
At the back of the garden I have a good patch of rhubarb. I don’t know what variety but the crowns came from an allotment neighbour and have always done well despite being a dry shaded patch of garden.
