Training Apple Trees for 'Step Over'
We are gathering information about training our apple trees into a 'Step Over'. We read in a book, "Plants for Small Spaces", by Clive Lane, that we could take 2 apple trees and train them to bend inward towards each other use a piece or wood in between them. We tie the trees to the wood I guess. What this creates is a horizontal line in which the apples would get full sunlight. We would just like to know if anyone has done this and if they have any information about it. Here are some other more specific questions we have regarding the "Step Over".
1. How far apart do you plant the two trees?
2. Can we use semi drawf trees or should we use full size trees?
3. How high should we put the piece of wood to train the trees when we tie the trees to the wood?
