Is common reed suitable for a garden pond?

Not for most. The RHS says it is a vigorous spreader that forms colonies, needs plenty of space and can become a nuisance. It is not suitable for small ponds. Plant it beside lakes, large ponds and wetlands, or in a large container.

Is it good for wildlife?

Large reedbeds of common reed are home to bitterns, marsh harriers and bearded tits. A garden clump is too small for these birds, but the RHS still suggests it for wildlife gardens.

How to plant and care for it

Plant in spring in shallow water or wet soil. Cut the stems back in late autumn or winter. It is generally free of pests and diseases.

Which size should I buy?

Bare-root plants (7 cm, 9 cm, 1 litre and 3 litre) arrive without a pot or compost and are the most economical way to plant a group. Potted plants (9 cm, 1 litre and 3 litre) arrive growing in our peat-free compost and give a faster display. Packs of 3 come in 7 cm, 9 cm, 1 litre and 3 litre bare-root sizes and cost less per plant. The 2x Pot & Compost option is two plants supplied with pots and compost.
