Pruning Periwinkle
When and how — Vinca minor
Prune your periwinkle in March — the optimal month is usually March.
The next pruning window is March next year.
When to prune?
The groundcover periwinkle is pruned in March.
Prune groundcovers to keep them in bounds.
Groundcovers are chosen for vigorous growth — and they deliver. So 'pruning' here is more about containment than shaping. Once a year, in spring, cut or shear the entire mat down to 5–10 cm. This refreshes the growth, prevents the centre from going woody, and keeps the carpet dense and healthy. For overgrown edges, take a sharp spade and cut a brutal straight line — the trimmings make ideal material for planting up elsewhere. Creeping species like vinca minor and pachysandra need little else; flowering groundcovers (geum, Geranium macrorrhizum) get a deadheading after the first flush.
How to prune periwinkle
Periwinkle requires very little pruning, but a light trim in March keeps it tidy and encourages fresh, vigorous growth for the season ahead. This is particularly useful if the foliage has become tatty over winter or if the plants have spread beyond their intended boundaries. Although periwinkle is evergreen, older leaves can look tired or damaged by late winter, and a spring cut rejuvenates the whole mat. Use garden shears, a strimmer on a high setting, or even a lawnmower with the blades raised to about 5–8 cm to shear back the entire planting. Don't worry about cutting too hard; periwinkle is robust and will regrow quickly from the base. If you're working with a smaller area or want more control, hand shears work perfectly well. Remove the clippings to prevent them from smothering new growth and to reduce the risk of fungal issues in damp conditions. If your periwinkle is encroaching on paths, borders, or other plants, March is also the time to cut back the trailing stems. Simply snip them off at the desired boundary. You can also lift and divide clumps if they've become too dense or if you want to propagate new plants for other areas of the garden. Periwinkle roots easily from stem cuttings and divisions. Beyond this annual tidy-up, the only other task is removing spent flower stems after the spring and late spring blooms fade, though this is optional. Deadheading won't encourage further flowering but does keep the groundcover looking neat if that matters to you.
Common mistakes
✗ Never cutting back
After 3–4 years the mat goes bald and woody in the centre. An annual early-spring cut prevents this and keeps the planting looking good for decades.
✗ Letting the edges run
Groundcovers quickly colonise paths and neighbouring borders. Cut the edges back cleanly every 4–6 weeks during the growing season.
Too late this year? Here's what to do
Better to wait than prune at the wrong moment. The next optimal window is March next year. Until then: leave the plant alone — only remove dead or diseased wood (which you can do year-round).
