The laurel by the front walk has been a ball for as long as you’ve lived here. Every summer someone shears it, and for a week it looks tidy. Push the outer leaves apart, though, and there’s nothing inside: a cage of bare brown stems with a green shell maybe four inches deep. Last year you asked for a lighter trim. It made no difference.
It’s healthy enough on the outside. Can it ever look like a laurel again, or is it time to pull it out?
Can a sheared shrub grow back to its natural shape?
Usually, yes, but not in one season. Restructuring pruning, done in winter and staged over a few years, opens the shrub up and lets it regrow into the shape its species wants to take.
The reason it’s bare inside is simple. Shearing cuts every shoot at the same surface, so the shrub branches just behind the cut and builds a dense outer shell. That shell blocks the light and air from the middle, and the inner leaves drop. Year after year the green layer gets thinner and the bare cage gets bigger. Shearing lighter doesn’t fix it, because the shell is still there.
What does fix it is cutting into the shrub instead of across it. That’s why the laurel by the walk didn’t change when you asked for a lighter trim: the trim was still a trim.
The first winter: opening it up
The first winter’s job is to let light back into the middle. The crew takes out some of the oldest, thickest stems at or near the base, and thins the shell so the inside can see the sky again.
Winter is the time for it because most shrubs are dormant. The cuts have the whole spring to push new growth, and with fewer leaves on, it’s easier to see which stems to take. Not everything comes out at once. Taking too much in one winter stresses the plant, so the work is spread over a few years, a portion at a time. For most shrubs, that’s no more than about a third in one winter. A shrub that needs a deeper restructure, and can take it, may lose more; that call is made plant by plant.
Be ready for the first spring. The shrub will look sparse, sometimes a little alarming, because you’re now seeing the bare stems the shell used to hide. Then new shoots start from inside, where there were none before. That’s the sign it’s working.
In between, the shrub is left alone to regrow. No summer shearing. If the same crew maintains the garden, they know the laurel is mid-restructure and leave it be; that’s one reason continuity matters for this kind of work.
The winters after: shaping what grew
The next winters shape the new growth. The crew chooses which new shoots to keep, takes out more of the old stems, and starts guiding the shrub toward its natural outline instead of a ball.
By now the inside has leaves again, and the shrub has started to look like what it is. Each winter’s cuts build on the last one, so it matters that the plan is written down and followed. We schedule pruning by plant type, so each species is cut at the right time of year. Every property gets its own annual calendar of seasonal work, so each task arrives when it’s due. A restructure is simply a few years of entries on that calendar.
How many winters? It depends on the species, its size and how long it’s been sheared. A few is typical. Anyone who promises a sheared shrub will look natural by summer is describing a different plant.
When replacing makes more sense
Not every sheared shrub is worth renovating. A mature shrub that’s also sick, or one that was planted in a spot too small for it, is often better replaced, and a good crew will say so at the first visit.
Mature and sick. If the shrub is old and declining, with dieback or disease, years of restructuring may end with a plant that still struggles. Replacing it is the more sensible plan.
Won’t regrow from bare wood. Some plants don’t push new growth from old, leafless stems. Most conifers fall into this group, including junipers, arborvitae, cypresses, pines and spruces: cut a branch back into the brown, needleless middle and it stays bare. Yew is the exception; it can be cut back hard and grow back. For the others, restructuring isn’t an option.
Wrong plant, wrong place. A shrub that wants to be eight feet wide in a three-foot bed by the walk will always need cutting back, however carefully it’s pruned. A smaller plant chosen for that spot is a lasting fix. We no longer run a nursery, but we still choose plants the way nursery people do. Picking the replacement is where that shows.
Who does the work, and how it's planned
Restructuring pruning is specialty pruning, quoted as an Enhancement. Our enhancements or maintenance manager advises on each shrub: whether to restructure or replace, and how the work is staged.
We regularly take on gardens that have been neglected or over-sheared, and bring them back. In our full-service area the work is available with or without a maintenance contract, and each winter’s stage is quoted in writing before it starts. For more on what a winter visit covers, see what your maintenance crew should do in winter.
The laurel by the walk, a few winters on
Go back to the green ball by the front walk with the bare cage inside.
The first winter, it lost its round shape and looked thin. By the next spring it had leaves in the middle again. A winter or two after that, it looked like a laurel: loose, layered, green all the way through, and the size the spot can hold.
Nobody sheared it into shape. It was opened up, left to grow, and pruned on its own calendar. If you have shrubs that have spent years as balls and boxes, see our landscape enhancements, and read why a maintained garden can still decline every year and pruning vs shearing.
