Creeping Jacob's ladder (Polemonium reptans): when to prune it?
In March to clear old foliage, and in June after the first flowering.
Creeping Jacob's ladder (Polemonium reptans): how to prune it?
- After flowering, cut the flower stems back to about 10 cm above the ground, or to the clump of leaves.
- Fresh new foliage soon replaces it and stays attractive for the rest of the season.
- In March, remove old, weathered foliage and dead stems.
How much to cut, and how often?
- There are 2 pruning periods a year: March and June. You don’t have to prune in every one.
What does it mean for wildlife?
- Creeping Jacob's ladder (Polemonium reptans) flowers in April–June, 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: On a variegated cultivar, remove shoots with entirely green leaves: they grow more strongly and can take over the variegated parts.
