Recently I watched The Victorian Kitchen Garden on youtube. BBC tried to restore a Victorian Era walled kitchen garden using old fruit and vegetable varieties and production methods. Apparently you can bury a paving stone in the ground and plant a standard fruit tree over it to make a dwarf tree. The tree?s taproot reaches the stone and stops growing. This retards the tree?s top growth and you get a dwarf tree. Does anyone know about this technique? Standard trees are usually a lot cheaper than dwarfs.
