Getting started

What is a weed? A weed is a plant growing where it is not wanted. Plants commonly referred to as weeds may have benefits for wildlife, but you may not want them growing in certain areas, or any part, of your garden.

Common weeds

We’ve selected some of the most common weeds. Flowers are particularly useful when identifying a plant, but leaves and growth habit, both above and below ground, will provide clues for identification.
