When do apple trees bloom?

1. The blooming time of apple trees varies according to the climate and environment of each region, and for different varieties of apple trees, the flowering period is also different. Generally, April to May is the main season for apple blooming, each flower bud has 3~7 flowers, and the central flower opens first. Apple is a cross-pollinated plant, and most varieties cannot set fruit by self-pollination. The proportion of various types of fruiting branches varies depending on tree age and variety.

2. Generally, after apple trees are planted, they begin to bear fruit only after 2-3 years. The length of the fruit growth period is generally 65-87 days for early-maturing varieties, 90-133 days for mid-maturing varieties, and 137-168 days for late-maturing varieties. Under normal circumstances, after planting, apple trees can have a lifespan of 15-50 years.
