How to trim primroses

1. Pruning branches

The pruning of primroses is very important, which determines how many flowers bloom in spring. generally, within 10 days after the flowers have withered, not only the withered and diseased branches need to be cut off, but also the old branches need to be cut off to avoid wasting nutrients, because there will be no flowers on the old branches, and pay attention to the branches that look densely distributed also need to be cut off, which is helpful to sprout new branches.

Second, carry out heart-picking

In order to prevent the new branches from growing so much that they are too long, it is usually necessary to pick the heart 2 or 3 times from May to July. When picking the heart, you only need to keep two pairs of buds, of course, depending on the specific situation. For the growth of the weaker branches should be less or not, through this method can make the tree shape more beautiful, while promoting the branch flowering.
