Ping Pong Purple globe amaranth problems — and how to fix them
Ping Pong Purple globe amaranth (Gomphrena globosa 'Ping Pong Purple') 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.
Crown rot in poorly drained containers
Compacted potting mix or containers without drainage holes can cause crown and root rot. Refresh potting mix annually and always use containers with drainage holes.
Fungus gnats in overwatered compost
Overly moist growing medium attracts fungus gnat larvae that damage roots. Allow the compost surface to dry between waterings and use yellow sticky traps to monitor adults.
Faded bloom colour in extreme heat
Prolonged temperatures above 38°C can bleach the purple pigment. Light afternoon shade during heat waves helps maintain colour; regular irrigation also reduces heat stress.
