Q.Columbine Problem
Once Columbines stop blooming, is the plant’s foliage suppose to look unsightly, dying, and diseased? I have leaf miners, dead leaves and dead stems. Is there a way to maintain that fresh, green, full foliage or is this just normal? Also, how much should Columbines be watered/fertilized after blooming? Thank you for your help.
Cutting the plant back following blooming can normally help with most issues. Neem oil, which is both an organic insecticide and fungicide, sprayed on the plants is also recommended for most problems. Here is more information: https://www.gardeningknowhow.com/special/children/columbine-flower.htm
