? The best time to prune a holly tree is in early spring when the new growth begins. This will encourage good health for your tree and also help it grow more quickly and remain healthy through the summer months. When you’re ready, here are some tips on how to prune a holly:
1) Eliminate old roots: Remove all of the small branches that appear near large limbs or multiple trunks. You can also remove any damaged or broken limbs from around the trunk; these slow down circulation, make older trees susceptible to disease and shorten life expectancy by up to 20 years!
2) Shrubs like light: Pruning shrubbery before winter encourages strong growth in springtime, which makes them much easier to maintain throughout fall and winter (when flowers have faded). After Christmas, consider cutting away dead foliage between 1/4″ – 3/8″ below ground level while dormant during dormancy. Take care not to pull up any underground stems as this could promote disease problems with your shrubs. As a general rule of thumb if an overgrown branch extends beyond three times its basal diameter then consider trimming it back so that it doesn’t get too heavy for younger branches growing underneath it..
3) Cut back branches close to trunk but leave at least 2″ of stem attached: Cutting off branches too far from their stalks reduces overall height because they don’t add additional wooded bulk above ground level where other plants may be able fill
