Field scabious: when to prune it?
In September, after the seed has set, mow or cut the plant back. If you leave stems in a border for insects, cut them down in March.
Field scabious: how to prune it?
- Mow a wildflower meadow in September, after seed set, and remove the cuttings to keep the soil poor.
- In a border, cut the spent stems back to just above the rosette of leaves.
- Leave a few stems over winter: insects overwinter in them and birds eat the seed.
- Cut away the last dead stems in March, before new growth begins.
How much to cut, and how often?
- There are 2 pruning periods a year: March and September. You don’t have to prune in every one.
What does it mean for wildlife?
- Field scabious 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.
- As a native plant, it feeds more insects than a non-native species.
