Lily of the valley
I have planted some lily of the valley pips in outdoor pots in April. They started to come up but now seem to be dying down. Should I still be watering them or should they die down to come up next year.
Lily of the Valley flowering lasts only 3 - 4 weeks. However, the leaves should remain green until late summer or early fall. Since your plants are in a pot, you need to be especially careful of the watering.
