Size of azaleas
No pruning is really essential for an azalea in the garden, but it can come in handy sometimes, if only to reduce or balance the antlers.
Pruning is done during the first 2-3 years of the azalea on young shoots and aims to promote branching.
- Pinch off new shoots with fingernails just above a leaf.
- Repeat the operation regularly so as to create as many new ramifications as possible.
- This pruning has the disadvantage of altering the flowering of the azalea, but it will make it denser, more robust and more flowering for the following years.
Maintenance pruning of azaleas:
The azalea can be pruned throughout its life, although it is recommended to prune as little as possible to keep a beautiful flowering each year and a natural shape.
- Start by removing dead, fragile wood and branches with little or no leaves.
- Once the flowers have wilted, prune just below the peduncle.
- To reduce the length of the branches, wait until the end of flowering.
- Be careful, severe pruning of your azalea compromises the next flowering.
