Sharp-petaled Schwantesia problems — and how to fix them
Sharp-petaled Schwantesia (Schwantesia acutipetala) 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 watering
The primary risk. During summer dormancy, only water if leaves become severely shrivelled, and even then very sparingly.
Poor flowering
Usually caused by insufficient light or missing the dry summer rest. Ensure a proper dormancy period and maximum winter sun.
Mealybugs
Hide in leaf axils and at the soil surface. Treat with isopropyl alcohol on a cotton swab or a dilute neem oil spray.
Leggy growth
Insufficient light causes stretching. Supplement with a grow light if a suitable window is not available.
