A second tier of branches should be established above the first scaffold. Two or three tiers of branches are enough on a dwarf tree. They point out that the leader must always remain in the highest point in the tree even though it can be pruned to keep the tree at the desired height. They say that as the fruit tree grows older it must be pruned so light and air can reach the fruit. Renewal pruning should be done from time to time since the size and quality of the fruit diminishes on old fruiting wood.
Spring pruning encourages more growth.
Allow two or three of the sprouts to grow. If they develop adequately, you may try bud grafting later in the summer or try more scion grafts next spring.
