Troubleshooting
Hedgehog Cactus problems — and how to fix them
Hedgehog Cactus (Echinopsis subdenudata) 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.
No flowers
Caused by a warm, watered winter. Provide a cool (around 8-10°C), dry rest to trigger the large night blooms.
Root rot
Its smooth body rots quickly in wet soil. Use gritty mix, water sparingly, and keep dry over winter.
Sunscald
Yellow or bleached patches on the spineless skin from sudden intense sun. Acclimatise to brighter light gradually and shade from harsh midday sun.
Mealybugs
White woolly clusters that hide in the wool tufts. Remove with an alcohol-dipped swab and inspect the roots.
