Large-flowered Tylecodon problems — and how to fix them
Large-flowered Tylecodon (Tylecodon grandiflorus) 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 rot from summer overwatering
The most frequent cause of death. When branches are bare in summer, the plant needs very little water. A single overwatering during peak dormancy can cause rapid collapse of the root system.
Failure to flower
Flowers (the plant's primary attraction) only develop after the plant has experienced a proper dry summer rest and at least a few years of growth. Insufficient summer drought or low light are the main inhibitors.
Mealybugs
White, cottony colonies can appear at branch junctions, especially in dry winter conditions. Treat promptly with isopropyl alcohol applied with a cotton swab, or a diluted neem oil spray.
