1. Why is there no result?

2. What to do if there is no result?

There are three reasons why it does not bloom or bear fruit. The first is the variety problem. The varieties planted are female flower varieties, which cannot be pollinated and fertilized, so they will not bear fruit. The second is improper pruning. If the overgrown branches are not pruned in time during the management period, the internal ventilation and light transmittance will be poor, and the failure to form flower buds will affect the results. The third reason is the climate. The flower spike itself is malnourished, and if it encounters continuous high temperatures or rainy weather, it will affect pollination and result in inability to bear fruit.

1. Why does it not bear fruit?

1. Variety problem: It may not bear fruit because of the variety problem. The variety planted is a female flower variety, which cannot be pollinated and fertilized, and will naturally not bear fruit. Common varieties include black chicken heart, mosaic white chicken heart, Anjiwen, etc.

2. Improper pruning: The plant grows vigorously during the management period, but If it is not pruned for a long time, the branches will become leggy, the inner branches and leaves will not see the light, and the bud eyes will not be mature enough, so the flower buds will not form and the fruit will not set.

3. Climate problems: If the flower spike itself is malnourished and encounters continuous rain or high temperature, pollination will be affected and fruit will not set normally.

2. What to do if there is no result

Now that you know the reasons for the failure, you should pay attention in advance. Prune in time during the growth stage to remove thin, diseased and duplicate branches to allow better ventilation and light transmission inside. Before the flowering period, an appropriate amount of fertilizer must be applied, mainly high-phosphorus fertilizer to promote flower bud differentiation. In addition, it helps with pollination. When blooming, you can wear gloves and touch the male flower buds so that the pollen will stick to the gloves. Then touch the female flower buds, which can help pollination and increase the fruit setting rate.
