Welsh poppy: when to prune it?
Cut off faded flowers regularly, from May. After the main flowering in July–August you can cut the plant back, and in March you clear away dead foliage.
Welsh poppy: how to prune it?
- Cut faded stems down to the leaf rosette, before the seed pods ripen.
- If the plant looks scruffy in late summer, cut it back by half for fresh foliage and a little late flowering.
- In March, remove dead or brown leaves and let a few flowers self-seed if you want new plants.
- Wear gloves: the yellow sap can irritate the skin of sensitive people.
How much to cut, and how often?
- There are 2 pruning periods a year: March and July–August. You don’t have to prune in every one.
What does it mean for wildlife?
- Welsh poppy flowers in May–September, when it attracts bees.
- 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: If you let all the seed pods ripen, the garden will be full of seedlings. Welsh poppy is poisonous: wear gloves and keep clippings away from children, pets and livestock.
