Oranges begin to develop flower buds in early winter. They develop slowly through the late winter into spring, usually blooming in April, and so many flowers are produced that up to 99 percent of them fall off without setting fruit.
The maturity Maturity is the stage of full production. In this stage the growth slows down and most of the energies of the tree are spent in flowering and fructifying and not in growing. The flowering and fruiting phase can last up to 30 years Read more
Prune the branch flush with the collar, not the trunk. This gives the tree the best chance to heal completely and minimize sprout growth. If the branch is larger than 1 ½ inches (4 cm.) across, use a three-part cut.
