The single most common hedge problem we're called about is a privacy screen that's thick and green on top and bare sticks at the bottom. Homeowners usually assume the plants are unhealthy or the wrong species. Almost always, it's how they've been cut.
The taper rule
Plants grow where light reaches them. If a hedge is cut with vertical sides — or worse, wider at the top than the bottom — the upper growth shades out everything beneath it. The lower branches get progressively less light, drop leaves, and eventually die back to bare wood. Once that happens on most species, it does not come back.
The fix is to shape the hedge slightly wider at the base than at the top. A subtle taper of a few degrees is enough. It looks nearly identical from a distance and it keeps light on the lower foliage, which keeps the screen dense all the way to the ground. This is the difference between a hedge that still looks good in ten years and one that needs replacing.
Shearing versus cutting back
Running hedge trimmers over the outer surface is fast and it's what most maintenance crews do. Done exclusively, it creates a dense shell of twiggy growth on the outside and a hollow, dead interior — which is why an over-sheared hedge looks catastrophic the moment something breaks the surface.
The better approach mixes shearing with periodic selective cuts back into the plant, reaching in to remove some older stems and open up the interior. That lets light penetrate and encourages growth from inside rather than just at the surface.
Timing in Central Texas
Late winter, before the spring flush, is the main structural cut for most evergreen screens — ligustrum, holly, wax myrtle, boxwood, arborvitae. Light shaping through the growing season keeps the line crisp.
Avoid hard cuts in the peak of summer. A shrub that loses a lot of foliage in July has to regrow it in the worst possible conditions, and the newly exposed inner wood can genuinely sunburn.
For flowering shrubs, the rule is simple: prune right after flowering. Cut a spring bloomer in winter and you're cutting off the flower buds it set last year.
Renovating an overgrown hedge
A hedge that's been neglected for years can often be brought back, but rarely in one cut. Taking an overgrown ligustrum or holly down hard all at once removes so much foliage that the plant may not have the reserves to recover.
We stage it instead — reducing over two or three cuts across a season or two, letting the plant respond between each. It takes longer and the result is a screen that's actually alive at the end of it.
Some species tolerate hard renovation better than others. Holly, ligustrum and wax myrtle generally respond well. Junipers and most conifers do not regenerate from bare wood at all, which means anything cut past the green never grows back. Getting that distinction right before the first cut matters.
Let us shape it
We trim hedges and shrubs to a true line, taper them properly, and stage renovation cuts on anything that's been let go. Clippings are bagged and hauled off — no piles at the curb.
