Trailing globe amaranth problems — and how to fix them
Trailing globe amaranth (Gomphrena serrata) 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.
Root rot in waterlogged containers
Trailing gomphrena is very susceptible to root rot in containers that retain too much moisture. Use a free-draining compost mixed with grit, and always ensure drainage holes are unobstructed.
Spider mites in hot, dry spells
Drought-stressed plants in very hot conditions may be colonised by spider mites. Increase irrigation slightly and apply neem oil or insecticidal soap to the undersides of affected leaves.
Loss of trailing habit in shade
Insufficient light causes upright, sparse growth rather than the characteristic spreading cascade. Relocate containers to a sunnier position to restore habit and bloom density.
