Yellow Tower Cactus problems — and how to fix them
Yellow Tower Cactus (Parodia leninghausii) 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
Overwatering in winter or in poor-draining soil causes rapid decline. Maintain a dry winter rest and ensure excellent drainage at all times.
Leaning growth
Naturally tilts toward the light source. Rotate the pot 180° every few weeks to maintain a straighter column.
Mealybugs
Hidden at the base or in the spine bundles. Treat with isopropyl alcohol on cotton swabs and monitor closely.
Pale or whitish spines
Indicates insufficient light. Increase direct sun exposure to restore the characteristic golden colouring.
Failure to flower
Flowering typically only begins when the plant is 15 cm or taller and has received adequate direct sun and a cool winter rest.
