In this climate a hedge can put on a surprising amount of growth between visits. The trick is trimming often enough that you never need to cut hard.
How often
For a formal, clipped look, every six to eight weeks in the growing season is common, and less in winter. A looser hedge can go longer. Fast growers get away from you sooner than slow ones.
Cutting back hard
Many hedges, especially those with dense green growth over bare wood, don't regrow from old wood. Cut too far in and you can be left with brown, bare patches that never come back. If a hedge is overgrown, it's often better to bring it back in stages over a season or two. If you're not sure what species you have, send a photo before anyone starts cutting.
Shape
A hedge that's slightly narrower at the top than the bottom gets more light on the lower branches, so it stays leafy to the ground. Flat tops and perfectly straight sides look neat but need more work.
Common hedge plants here
Lilly pillies are popular and respond well to regular trimming, though they can get a pest that curls and discolours new leaves. Murraya (orange jasmine) is another favourite for screening. Westringia and other natives make a softer, lower hedge. Fast growers fill in quickly but need trimming more often. If you're planning a new hedge, ask about the mature size so you don't create a maintenance job in a few years.
Boundary hedges
If a hedge runs along a boundary, it's worth a chat with the neighbour before you cut. Agree on height and who does which side. It avoids awkward moments.
Trees are different
A hedge is one thing and a tree is another. In Byron Shire and neighbouring councils, pruning or removing trees on private land can need a permit, depending on the zoning, the species and the size of the cut. Councils have issued fines for unauthorised clearing. Check with your council first if you're unsure.
Ladders and power tools
A ladder and a running trimmer is a bad combination. If you can't reach the top from the ground or from a stable platform, it's worth getting someone in. Keep cords away from the blades and away from wet ground.
Nesting birds
Check for nests before a big cut, and leave them alone if you find an active one.
Cleaning up
Trimmings pile up quickly. Green waste removal is part of the job on our visits. See garden and hedge care. Tall hedges and anything that needs climbing gear are outside what we do, and we'll say so.
Tools matter
Sharp blades make clean cuts that heal faster. Blunt ones tear the foliage and leave brown tips. If you trim your own, keep the blades sharp and clean.
Common mistakes
- Cutting flat into old bare wood on species that won't regrow from it
- Leaving it so long that a heavy cut is the only option
- Trimming in extreme heat, which can scorch fresh growth
