The reason and solution of fig's failure to bear fruit is first of all the problem of planting years. Ficus carica is very productive, and it usually takes about two years to bear fruit, but the fruit bearing effect of Ficus carica trees planted for two years is not very good. If the fruit tree grows slender, it is likely to have little or no fruit. Therefore, if you plant a fig tree for less than two years, it will probably not bear fruit. Don't worry about the fig tree in this case. When it is long enough to bear fruit, it will bear fruit naturally.
Light problem: This point needs to consider the growth habits of figs. Figs like the growth environment with sufficient light, and good light can promote figs to bear more fruits. If our planting environment is too dark and the light is insufficient, it is easy for figs to grow leaves without fruit. For such figs, all we have to do is transplant them in time or move them to sunny places.
Pests and diseases: Generally speaking, fig trees rarely have insects, and because of the special smell of fig trees, they have certain insect repellent effect. But one kind of insect likes fig trees very much, and that is longicorn. If you find longicorn beetles near your fig tree, you should pay attention at this time. They have begun to attack your fig tree. Long-horned beetles will look for fig trees and lay eggs on them. Larvae of the horned beetle will grow on the trunk of the fig tree and eat the xylem of the trunk of the fig tree. Larvae of the horned beetle will grow for a very long time, usually in several years to ten years, which means that the fig tree may be bitten by the larva of the horned beetle, so it is difficult for the fig tree to bear fruit naturally. If longicorn beetles are found near the fig tree and sawdust and wormholes appear under the trunk, the fig tree should be treated in time.
For longicorn pests on fig trees, you can choose to catch them manually or use a spray specially used to kill longicorn larvae. These sprays generally have special nozzles, and you can spray them at the wormholes of Anoplophora longicorn larvae.
