Weeds generally fall into two types: annuals, which grow and die within a single season, and perennials, which are more persistent and return year after year from their roots. Annual weeds are relatively easy to manage—simply burying them while digging is often enough. Perennials, however, are more stubborn and need to be dug out thoroughly to remove their root systems.

This really useful guide from the Saintbridge Allotment Gardens Association offers practical advice on:

• Using winter digging to tackle deep-rooted perennial weeds

• Employing regular hoeing to keep annual weeds in check
