Troubleshooting
Duvalia corderoyi problems — and how to fix them
Duvalia corderoyi (Duvalia corderoyi) 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.
Rot from overwatering
Soft, blackening stems and collapse follow soggy soil, especially in cool months. Water only when fully dry, never in winter, and grow in a gritty open mix.
Mealybugs and root mealybugs
Cottony white pests lodge among the dense stems and on the roots. Spot-treat with alcohol or a systemic product and check the root ball when repotting.
Failure to flower
Usually caused by insufficient light or no winter rest. Give brighter light in summer and a cool, dry dormant period to trigger the maroon blooms.
Sunburn
Pale or scorched patches on stems from sudden exposure to strong direct sun. Acclimatise gradually and shade from fierce midday glass-filtered light.
