Troubleshooting
Lithops Optica 'Rubra' problems — and how to fix them
Lithops Optica 'Rubra' (Lithops optica 'Rubra') 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.
Loss of red colour
Insufficient light reverts the body to green. Move to your brightest spot or add a strong grow light to restore the purple-red pigment.
Soft, rotting body
Off-season or excessive watering causes mushy collapse. Water only during active growth and keep the substrate predominantly mineral.
Splitting or bursting
Watering too heavily or too late in the growth cycle swells and cracks the leaf surface. Use light soaks and stop before dormancy.
Etiolation
Low light elongates the body and weakens the form. Increase light to keep the compact, squat shape.
