Large-flowered tickseed (Coreopsis grandiflora): how to prune it?
- Cut spent flowers with their stalks back to a leaf or a new bud.
- If flowering slows down in August, cut the plant back by a third: a new flush of flowers follows a few weeks later.
- Leave the old stems over winter; they give the crown a little protection.
- In March, cut everything back to just above the young leaf rosettes.
How much to cut, and how often?
- There are 2 pruning periods a year: March and June–September. You don’t have to prune in every one.
What does it mean for wildlife?
- Large-flowered tickseed (Coreopsis grandiflora) flowers in June–September, when it attracts bees and butterflies.
- If pruning falls during flowering, wait until it is over or leave part of the plant to flower, so bees and butterflies still benefit.
Caution: Do not cut down to the ground in autumn: a plant left completely bare over winter rots more easily.
