3 grafted varieties on apple tree
Hi, i hope you can help. I have a dwarf apple tree about 5 years old. It has grafted on it 3 different varieties. The most dominant variety is golden delicious, the 2 other grafts aren’t very strong with fairly weedy branches. What can i do to make the weak branches stronger and the golden delicious branches less vigorous? I have pruned the golden del more that the other 2 this jan. thanks for any advice.
