1, Myrica rubra doesn't bear fruit, maybe it doesn't bear fruit if it is not old enough. Because bayberry trees need to grow for 4-5 years to bear fruit, in general, it takes 4-5 years for grafted bayberry trees to blossom and bear fruit, so bayberry trees need to grow for a certain number of years to bear fruit.

2. It is possible that there are no male trees nearby that can pollinate. Myrica rubra generally needs insects or artificial pollination to bear fruit. If too few Myrica rubra trees are planted, it happens that all Myrica rubra trees are female, and there are no Myrica rubra trees nearby that can be pollinated, which will lead to pollination, and ultimately the Myrica rubra trees will not bear fruit.

3. If Myrica rubra does not bear fruit, it means that Myrica rubra may be a male tree, but the male tree will not bear fruit. Generally, bayberry is dioecious. If the growth conditions are good and Myrica rubra still does not bear fruit, it is very likely that you will encounter a Myrica rubra tree that does not bear fruit.

Myrica rubra is a light-loving plant. If planted in a cool place, insufficient light will affect the growth of Myrica rubra, resulting in Myrica rubra bearing no fruit.
