Thrift problems — and how to fix them
Thrift (Armeria maritima) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Crown rot
The most common killer of Armeria; caused by wet, heavy, or poorly drained soil sitting against the crown. Ensure sharp drainage and avoid mulching directly over the crown.
Rust fungus
Orange or brown pustules appear on leaves in humid conditions. Remove and dispose of affected foliage, improve air circulation, and avoid overhead watering.
