Step-by-Step Pruning Guide
Start by removing any dead, damaged, or diseased branches. This is crucial as it prevents the spread of disease and allows the plant to focus its energy on healthy growth. Next, cut back the branches to shape the shrub, ensuring it maintains a natural form. Aim to cut about one-third of the older wood back to the base of the plant to encourage new shoots.
