As landscape architects and arborists we often find that plant material on our new residential, commercial and HOA sites have been left to get overgrown and mismanaged. The key to getting the plant material looking healthy, vibrant and growing properly again is of course dormant pruning.
Dormant pruning takes place during the winter months and this is valuable for many reasons. With the leaves absent precision pruning is much easier. Cutting the plant in the right spot helps the plant heal better and faster in the growing season. It also allows us to see the shape of the plant better and see limbs and stems that are either damaged, diseased or crossing. The colder months also mean less airborne diseases that could affect the fresh wounds of plants.
A sure sign that dormant pruning needs to be done is the evidence of witches broom which is a dense mass of shoots growing from a single point. This happens when the plant is perpetually pruned or sheared on the top and never in the middle or base of the plant. This type of pruning leads to a plant that is top heavy with leaves, but looks bare and leggy on the stems and base.
Dormant pruning removes the witches broom, allows us to remove overgrown stems at the base of the plant and makes it easier to remove unwanted growth. These fixes allow sunlight and air to get to the entire plant and not only to the top sections. Heights of plants are also much more easily controlled during dormant pruning allowing the plant to take on a natural shape during the growing season without blocking windows or doors.
