How to improve the fruit setting rate of prunes? There are two ways to improve the fruit setting rate of prunes. The first method is to collect pollen from the bud at the beginning of flowering and apply it to the stigma with a brush. This method consumes manpower, but the pollination effect is good. The second method is to pat the flower branches gently with a wooden stick wrapped in cotton balls after entering the full flowering period, so that the pollen falls on the stigma.

In the process of cultivating prunes, it is necessary to cultivate fruiting branches through shaping to improve the permeability between plants. Plastic surgery is best done in winter. Keep 3-4 strong main branches on the branches, remove the remaining main branches, and then cut off the remaining 2/3. In the same way, keep 3-4 side branches on each main branch and cut off the remaining side branches.
