Pruning is simple, to create an open canopy form from five main branches. Pruning should be done while the tree is dormant, throughout the winter, and a few weeks before spring. It will vary greatly depending on the geographical location of the trees. Make use of high-quality, clean-cutting instruments.
Applying a disinfectant to the cutting blades beforehand isn’t a bad idea. Begin by eliminating any branches that are crossed, weak, sick, or dead. Keep the tree’s center open; if multiple heavy branches need to be pruned, we’ll space them out over time. So that the tree does not suffer significantly throughout two or three winters.
When in a colder climate zone, it is recommended to thin the leaves by pruning to allow light to penetrate well. In young specimens, pick the flowers when they fade to prevent them from turning into fruit, which wastes energy in the plant.
Removing faded flowers can further prolong flowering time. Cut upward-growing branches close to a lower branch with a diameter of at least one-third that of the one being removed.
