How to prune snapdragons
The snapdragon is a feature of British gardens. (Igor Groshev)

Blooming throughout the spring and summer, the snapdragon is a low-maintenance plant with large, colourful, narrow flowers and a slight fragrance. A native to the Mediterranean, a snapdragon can grow up to 90 cm (3 feet) tall. The snapdragon loves the sun and thrives in well-fertilised soil. It is deer-resistant and easy to start from seed, although it is self-sowing. Pruning your snapdragon will promote more growth and strengthen the plant overall.

Things you need

  • Peat or compost

  1. 1

    Cut the spent bloom of the snapdragon down to the green growth. This will encourage growth of more flower stems through the blooming season.

  2. 2

    Cut your snapdragon back in the summer with pruning shears after it has stopped blooming and water deeply. This will produce blooms in the fall.

  3. 3

    Add organic material, such as peat and compost, to your soil when you cut back your snapdragons. This will improve the fertility of the soil the following year.
