Perennial weeds
Perennial weeds are more of a problem because they can live for several years. They survive the winter by storing food in their roots. These roots make them harder to get rid of than annual weeds. Some are difficult to dig out and others spread underground. If you leave even the tiniest piece of root in the soil when you dig them out, you’ll get a whole new plant.

To control:
- Dig out perennial weeds as soon as you see them. So long as you don’t let them produce leaves, the roots will use up their energy stores and eventually die. Never rotavate soils with perennial weed infestations as it is a brilliant way of propagating them! Always dig out every little bit as they will regrow and often with twice the vigour.
- If you don’t mind using chemicals, treat them with a weedkiller containing glyphosate.
- Never put perennial weed roots or seed-heads on to the compost heap.
