When can you trim rhodadenrum?

You can trim rhododendrons after they finish blooming in late spring or early summer. This timing allows you to avoid cutting off the flower buds that develop for the next year's blooms. If necessary, you can also perform light pruning in late winter or early spring before new growth begins, but be careful not to remove too much foliage. Always use clean, sharp tools to make clean cuts and minimize stress on the plant.
