How do you prevent peach fruit drop? The latest methods are here

Friends who grow peaches at home may have noticed that peach trees often bloom heavily and set a lot of fruit, but not long after fruit set, many small, green peaches drop to the ground, and in the end only a small portion of the fruit remains to set and ripen. This is rather unsatisfactory, so why does this happen, and how do we solve this problem and improve the fruit-setting rate? Please see the article below.

1. Causes of fruit drop

First, too many flowers bloom and no flower thinning is done, so many fruits set, but the tree's nutrition is insufficient and cannot supply so many fruits, so they simply drop. Or the tree itself is relatively weak in growth and lacks nutrition, and no fertilizer is added, which causes fruit drop. There is also the physiological fruit drop that peach trees themselves have. In addition, if it rains during the flowering period, pollen is lost and pollination and fertilization are poor, causing incomplete development and deformed fruit drop. Finally, excessive application of nitrogen fertilizer causes vigorous shoot growth, and after the fruit's nutrition is competed for, the fruit drops.

2. Preventive measures

1. Flower and fruit thinning

This can be done when about 60% of the flowers have opened. Generally, for clustered flowers, remove the weak and keep the strong; for a cluster of five or six flowers, keeping two or three is enough. All incompletely developed flowers will fall off if the branches are shaken gently. For flowers on weak branches, remove the flowers at the same node and keep 40% of the flowers; for flowers on strong branches, keep about 65%. Two months after fruit set, begin fruit thinning, keeping fruit at relatively spaced nodes. If there are too many on the same side, remove some. Also, keep more fruit on robust branches and fewer on thin, weak branches. Remove fruit on water sprouts when pruning, and the same for drooping branches.

2. Ensure nutrition

In addition to 4 flower and fruit thinning, also prune out dead branches, overlapping branches, water sprouts, drooping branches, and dense inner branches. Pick some old leaves to reduce nutrient consumption. For fertilization, apply sufficient base fertilizer in spring, and topdressing is indispensable. During the entire fruiting period, topdress three times. Do not apply only nitrogen fertilizer; apply compound fertilizer. Watering should be done three days after topdressing, and you can water multiple times depending on the soil condition, but water should be controlled during the flowering period.

3. Artificial pollination and spraying fruit-setting agents

You can pollinate by hand, pollinating before the rainy season. If it rains after pollination, you can pollinate once more. Pay attention to the weather and try to complete the pollination and fertilization process before it rains. Artificial pollination can ensure the success rate of pollination and fertilization. Avoid the phenomenon of incomplete development. Ensuring more fruit set means more fruit will set. In addition, after fruit set, you can spray Guodiling to protect the fruit.

Too much peach fruit drop is abnormal. You should first look for the cause and improve the fruit drop problem according to the root of the problem. Also, once you know the cause, you will know how to prevent it in the future. The peach fruit drop problem can be improved through the above measures.
