What branches to prune in hydrangeas

During its growth the hydrangea will produce several types of branch. It is vitally important that we know how to recognize them at a glance to facilitate the work when pruning. Thus, these are the types of branches and stems of hydrangeas and which we should prune and which we should not:

  • Old branches : they are the most woody branches that are usually found in the central area of ​​the bush. We must eliminate them completely to prevent them from absorbing nutrients and that this leads to a loss of energy from the rest of the newer branches.
  • Branches of about three years: they are young branches that have grown over six buds. Of these we must eliminate approximately 50%, always favoring the penetration of light throughout the bush. In case these end up in flower, we will make a cut above the bud.
  • Suckers: they are the youngest branches. They have an elongated stem that always ends in flower. Unlike the other two types of branch, we must not cut them. Suckers promote flowering and rejuvenation of hydrangeas.

  2. Then select the young branches and always cut above the bud. Try at all times to create an open arrangement of the bush for light to penetrate. Use here a hand scissors to facilitate access to as many branches as possible. Do not forget that reducing the size of the plant will favor its flowering.
  3. Finally, water and fertilize your hydrangea with special fertilizer for them. Hydrangeas are acidic soil plants, so we recommend that you use a low pH substrate and a specific fertilizer for hydrangeas. In addition, in this way, you will get that blue color so representative of these flowers.

Other tips for pruning hydrangeas

A little trick to never forget when to prune a hydrangea regardless of its type, is to prune just when the last flower fades . The flowers provide protection to the hydrangea during frost, so they are essential to maintain the health of our plant and, therefore, it is convenient to wait until they no longer remain.

In addition, to get good hydrangea cuttings , we must make them just when the flowers begin to harden. For its reproduction by cuttings we will cut the flowers and leave at least three nodes, eliminating the leaves closest to the base and reducing the remaining ones by half. Learn more about How to make cuttings with this other post.
