Sheared hedges are formal hedges. They can be very attractive. They can also be pretty boring or even absurd if they do not match the larger landscape. Most homes in the Southeastern U.S. are not best complimented by formal hedges. However, if sheared, formal hedges are what you need, thinning should be done along with shearing. Repeated shearing causes thick branching ( I have seen some that a golf ball could not penetrate!), which inhibits sunlight and airflow; conditions that foster buildup of insects and disease. Use sharp hand clippers to remove branch clusters back to a branch crotch. This is a little scary for some since it creates small gaps in the smooth hedge. The effect is an airier look and a situation that is not so conducive to pests.

When shearing, taper sides outward from the top. It is important that the bottom flare outward slightly so that the bottom limbs will not be shaded and die, creating a ‘lollipop’ hedge.

For drastic size reduction, most Japanese and dwarf yaupon hollies can be pruned to within a few inches of the ground and recover nicely. This is best done in early spring so the plant will not be bare for very long. They will need a second (or even third) pruning by summer to encourage branching. Do not prune boxwood this way. Boxwood are about the only shrub that can be killed by severe pruning or pruning at the incorrect time.. More on that next week…
