How to keep plum flowers and fruits when they bloom

1. Apply foliar fertilizer

When the flowers just start to bloom, you can apply foliar fertilizer to the leaves. You can use a low-concentration urea solution, which can promote the differentiation of flower buds. You should also spray it when the flowers are in full bloom and during the growth period of young fruits. In addition to the urea solution, you should also mix it with 0.4% potassium dihydrogen phosphate solution. Foliar fertilization can effectively reduce the drop of flowers and fruits and increase the fruit setting rate of plum trees.

2. Ringing

This method is for trees that have grown for 12-15 years and have reached the peak fruit-bearing period. You can choose to ring-bark during the peak flowering period. Use a sharp knife to cut two circles on the trunk about 15 cm from the ground. Keep the width at about 4-6 mm, and then peel off the skin. This step cannot be performed on small trees or trees with weak growth.

3. Spraying during flowering period

After entering the peak flowering period, you can spray 300 times diluted borax or boric acid on the trees. This can increase the fruit set rate and the effect is very significant.

4. Cut off the flower buds

For trees that produce a lot of flowers, you can cut off some of the small flower buds when they just start to bloom, which can also help.
