Rebutia krainziana problems — and how to fix them
Rebutia krainziana (Rebutia krainziana) 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.
Root and basal rot
From overwatering or a winter wet rest. Roots turn brown and mushy and heads soften. Use a free-draining mineral mix and keep dry in cold months.
Etiolation (stretching)
Pale, elongated growth with widely spaced spines signals too little light. Move to the brightest window; stretched tissue won't recover its compact form.
No flowers
Almost always caused by a too-warm or too-wet winter. The plant needs a cool (around 8-12°C), bone-dry rest to set buds the following spring.
Red spider mite
Fine webbing and rusty stippling on the skin in hot, dry, stagnant conditions. Improve airflow, rinse the plant, and treat with a miticide if needed.
