Asters

Question

My asters have brown stems from the ground up 2-3 inches and the leaves are dried up and crumbly. Any ideas why and how to treat?

Answer 1

Underwatering and heat stress is the most likely culprit in this scenario. Try watering more often or witha greater amount of water and see if that helps. Also check for any visible insects on the plants, just in case it is a pest issue.

Fusarium wilt could potentially match your plants' symptoms. Check the description in this article:
