Conophytum Calculus problems — and how to fix them
Conophytum Calculus (Conophytum calculus) 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.
Summer rot
Watering during the hot dormancy rots the resting pebbles. Keep entirely dry from late spring until autumn growth resumes.
Bodies splitting or cracking
Heavy or late watering swells and bursts the round bodies. Use light soaks and stop before dormancy.
Loss of compact form
Low light flattens and loosens the spheres. Move to brighter light while shading the harshest summer sun.
Mealybugs
Pests hide among clustered bodies and old sheaths. Inspect regularly and spot-treat with 70% isopropyl alcohol.
