Meyer's Cape Primrose problems — and how to fix them
Meyer's Cape Primrose (Streptocarpus meyeri) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Leaf yellowing from overwatering
This drought-adapted species is particularly prone to yellowing lower leaves and root rot if kept too moist; let the compost dry noticeably between waterings and ensure the pot has multiple drainage holes.
Mealy bug
Waxy white cottony clusters appear in leaf axils and on petioles; mealy bug sap-feeding causes stunted, distorted growth. Treat with a cotton swab dipped in 70% isopropyl alcohol to dab individual colonies, or apply a neem-oil drench to the compost.
