Golden Glow bougainvillea problems — and how to fix them
Golden Glow bougainvillea (Bougainvillea 'Golden Glow') 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.
Bract colour fading
Golden bracts can fade to washed-out cream in insufficient light or extreme heat. Ensure maximum sun exposure. Some colour change as bracts age is normal and contributes to the cultivar's multi-tone appeal.
Root rot in containers
Overwatering or blocked drainage holes cause rapid root rot, showing as wilting with wet soil. Check drainage holes are clear, reduce watering immediately, remove rotted roots, and treat with a fungicide such as fosetyl-aluminium if caught early.
Whitefly under glass
Greenhouse whitefly colonise the underside of leaves in warm, enclosed environments. Introduce the parasitic wasp Encarsia formosa as biological control, or use yellow sticky traps alongside an insecticidal soap spray programme.
