The leaves change color and fall. The gardening season is surely coming to an end. What will become of the lily in the perennial border or in the pot? It should not be overwintered without a cut!
Outdoor lily bulbs should be dug up after pruning the lily and overwintered in a cool, dry place
Shorten radically before winter
If the hardy lilies are to remain in the bed throughout the winter, they should be pruned before the first frost. Many make the mistake of making the cut too early. Only when the above-ground parts of the plant, such as leaves and stems, have yellowed, is the radical pruning carried out down to the ground.
Potted lilies are also pruned as winter approaches. Then they should be winterized:
- either: wrap the pot in jute and place it on a wooden board in a protected place
- or: Overwinter the onion (dig up and quarter it)
tips and tricks
Only use clean and ideally disinfected tools for cutting. Otherwise there is a risk that the lily will be attacked by pathogens.
