Gaillardia 'Goblin' problems — and how to fix them
Gaillardia 'Goblin' (Gaillardia x grandiflora 'Goblin') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Short-lived / crown rot
Often behaves as a short-lived perennial, especially in wet or rich soil. Sharp drainage and avoiding winter wet extend its life.
Powdery mildew
White coating on leaves in humid, crowded conditions. Improve airflow, avoid overhead watering, and space plants well.
Aster yellows
A leafhopper-spread phytoplasma causing distorted, greenish flowers. Remove and destroy affected plants; there is no cure.
Flopping / legginess
Caused by too much shade or over-feeding. Site in full sun and keep soil lean for sturdy, compact growth.
