Tavaresia grandiflora problems — and how to fix them
Tavaresia grandiflora (Tavaresia grandiflora) 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 on own roots
Soft-stemmed and rot-prone, it collapses if overwatered or kept cold and damp. Keep dry and warm; many growers graft it for reliable long-term survival.
Mealybugs
Cottony white pests settle among the soft spines and stem ribs. Treat with alcohol and inspect the root ball for hidden root mealybugs.
Weak, stretched stems
Low light causes thin etiolated growth more vulnerable to rot. Give bright light with gentle direct sun to keep stems stocky and well coloured.
Chill injury
Cold below about 5C produces mushy, translucent patches. Overwinter above 10-12C and dry to prevent frost and cold-wet damage.
