So I’m pruning back this climber I think it’s a coma but can you tell me what it is and what should we do
6 October 2026

Yes — this looks very much like a **Clematis** rather than “coma” 😊. The thin twining stems, small green leaflets and the fluffy seed remains suggest clematis. There is a lot of dead/browned growth in the middle, which is quite normal at this time of year, especially if it’s a late-flowering type.
### What to do now — early October
Because we don’t yet know which pruning group it is, I’d avoid cutting it hard back today unless it’s completely out of control.
Do this now:
1. **Remove anything clearly dead**
- Cut out black, crispy, brittle stems.
- If a stem snaps easily and is brown inside, it’s dead.
- If it bends and has green inside, leave it.
2. **Untangle and reduce the worst of the mess**
- Cut back long, loose, straggly stems that are hanging into paths, seating areas or other plants.
- Take them back to a healthy pair of buds or a side shoot.
3. **Leave some main stems in place**
- If this is an early-flowering clematis, next year’s flowers may already be forming on old wood.
- Cutting everything down now could remove next spring’s flowers.
4. **Tie in healthy stems**
- Spread the remaining stems out over wires, trellis or the support.
- Clematis flowers better when growth is fanned out rather than bundled into a tangled ball.
### Main pruning — best done in late winter
In **February or early March**, you can make the proper pruning decision:
- **If it flowers in spring**, prune lightly after flowering only.
- **If it flowers in early summer with large flowers**, prune lightly in late winter, just removing dead growth.
- **If it flowers in late summer/autumn**, cut it hard back in late winter to around **30–60cm from the ground**, just above strong buds.
From the look of this plant, it may well be a **late-flowering clematis**, in which case it can take quite a hard prune in late winter — but I’d confirm by when it flowers.
### Feed and mulch
After pruning in late winter/spring, give it:
- A handful of general fertiliser such as Growmore around the base.
- A mulch of compost or well-rotted manure.
- Keep the roots cool and moist, especially if it’s planted near paving or a wall.
### Quick check
Can you remember when it flowers — spring, early summer, or late summer? And what colour are the flowers? That will tell us exactly which clematis pruning group it belongs to.
