What should I do if plum trees bloom and don't bear fruit?

The reason why plum blossoms do not bear fruit.

Performance: plum trees will wither and bear no fruit after flowering.

Reason: There are many reasons that make plum trees blossom and bear no fruit, such as improper pollination, improper fertilization, pests and diseases, etc.

Treatment method of plum blossom without fruit

If it is because of too little fertilization that plum blossoms fail to bear fruit, it is necessary to topdressing in time, and attention should be paid to the coordinated application of nitrogen, phosphorus and potassium fertilizers when topdressing.

If it is caused by improper pollination, pollination trees can be configured or artificial pollination can be carried out at this time, and bees can be released during flowering to remedy it.

If plum trees only blossom but do not bear fruit due to diseases and insect pests, it is necessary to strengthen the prevention and control of scale insects. Because of the widespread harm of scale insects in Li Ziyuan, 50% cartap 1500 times solution is generally used for control.

Plum trees prevent flowering and fruiting.

1. Water and fertilizer management: Apply less chemical fertilizer and more organic fertilizer before plum trees bear fruit. Fertilizer should be applied in early spring and after autumn, so as not to cause excessive tree vigor and insufficient flower buds, which will affect the results.

The amount of chemical fertilizer, especially phosphorus and potassium fertilizer, can be gradually increased in the full fruit stage, and nutrition should be supplemented in the flower bud differentiation stage to promote flower bud differentiation and fruit expansion. Water in spring should promote flowers, and water in summer and autumn should control the tops to make the trees strong but not prosperous.

2. Postpone the flowering period of plum trees: The main measures to postpone the flowering period are irrigation in early spring, using chemical reagents, painting the trunk white, etc., mainly to avoid the influence of late spring cold on plum trees. If the flowering period cannot be postponed, anti-freezing measures should be taken in time to ensure that it will not suffer from freezing damage.

3. Artificial pollination: Artificial pollination can also be carried out on the basis of rational allocation of pollination trees and good measures for releasing bees at flowering stage. In case of abnormal weather such as low temperature, rainy weather and sandstorm, artificial pollination can be carried out to improve the seed setting rate.
