pinching back lamb's ear
Each year after flowering, my the leaves on my lamb's ear rot and look disgusting. Will pinching them back to prevent flowering help? Or is there anything else I can do? I hate to sacrifice the flowers -- they're not so impressive but the purple is pretty agains the silver leaves, and the bees love them.

Lamb's ears like full sun, fairly dry conditions, and good air circulation to avoid leaf spots and rots. The fuzzy leaves of lamb's ears can hold moisture which leads to fungal leaf spots. Full sun and good air circulation prevent the conditions favorable for fungal growth.
Avoid overhead watering, plant them where they get plenty of sun. Remove flower stalks after flowering. Remove any infected leaves from the site as soon as they appear.
