Many hedges become thin at the bottom or develop bare patches over time. That does not always mean you need to rip them out and start again – careful pruning, feeding and gap-filling can often bring them back.
Basic thickening plan
- Reduce the height slightly to encourage side shoots.
- Trim sides so they are a little narrower at the top than the bottom.
- Feed and water if the soil is poor and dry.
- Plant new shrubs in the worst gaps if needed.
Encouraging new growth
Hedges thicken up when many small shoots grow, not when a few long stems stretch out.
- Lightly reduce the height to stimulate new side branches.
- Trim side growth to create a tapered shape – wider at the base.
- Avoid cutting back to bare, lifeless wood on species that do not re-sprout well.
Feeding and watering
Tired hedges often respond well to a bit of extra care.
- Apply a balanced fertiliser in spring, following the packet instructions.
- Add mulch around the base to help keep moisture in and weeds down.
- Water deeply during dry spells, especially for recently planted sections.
Filling larger gaps
If there are sections with no live stems, consider planting new shrubs in the gaps.
- Choose plants that match or complement the existing hedge.
- Stagger new plants slightly in front or behind the main line if needed.
Summary
With the right pruning, feeding and occasional re-planting, many thin hedges can be thickened up over a couple of seasons. It is usually cheaper and less disruptive than replacing the whole thing in one go.
