Deadheading plants encourages them to produce another flush of flowers, rather than expending energy on the formation of fruit and seed. Find out more about the benefits of deadheading.
Plants that benefit from deadheading include herbaceous perennials, roses, bedding and annuals. Some will cope with a ‘free and easy’ approach, while others require a bit more care.

For shrubs that bloom only once in a season, such as camellias and lilacs, removing the old flowers helps to conserve the plant’s resources so it can maintain healthy leaf and root growth. Just pinch off old blooms.
Deadhead Choisya ternata right after flowering is over – usually in June. Simply cut back spent flower clusters to a healthy bud.
Hebes will need some deadheading to lengthen flowering time and improve their appearance. Cut back spent blooms to the base of the flower.
Lavateras can be encouraged to continue flowering if you deadhead the flowers before seed heads begin to form.
Old peony blooms are easy to spot and they can spoil the appearance of the plant. Cut the spent flowers at the base, to prevent the production of seeds.
Remove the spent flower clusters on pieris shrubs by cutting back to a healthy bud. Don’t deadhead too late, as you may cut into the new growth that will produce next year’s blooms.
Buddleja flowers quickly turn brown once they’ve finished their display, giving the plant a tatty appearance. Prune old blooms at their base to improve their appearance and to encourage further blooms.
