1, pruning the diseased leaves of the stump.
During the growth of hydrangea, it is inevitable that some diseased leaves will appear, so it should be pruned in time in spring to avoid the waste of nutrition and bacterial infection, so that the plant can concentrate nutrition and be beneficial to the next flowering.
Step 2 prune rotten flowers
Hydrangea needs to consume a lot of nutrients to keep the flowers open. In order to avoid excessive waste of nutrients, when the flowers begin to rot and are not ornamental, the residual flowers can be trimmed directly from the branches below the flowers.
3. Dead branches after pruning flowers
There will be a certain amount of dead branches after hydrangea blooms, so we must always observe the growth of plants in spring. If dead branches are found, they can be pruned above the healthy bud point to concentrate nutrients on the bud point and promote their germination and growth.
Step 4 Trim the shape of the branches
Domestic hydrangea potted plants naturally want beautiful shapes. If too dense and too long branches and weak branches are found in spring, they need to be thinned properly to make the hydrangea more stretched and the plant shape more beautiful.
5, different varieties of pruning
Generally speaking, hydrangea can be roughly divided into native hydrangea and exotic hydrangea. Soil hydrangea mainly blooms with old branches, and only diseased branches need to be cut off in spring; However, the post-flowering pruning of foreign hydrangea should take into account the later modeling. To make the plant form a ball, the middle part needs to be smoother and the edge part needs to be cut short, so the shape will be more beautiful.
