Pinnate Primulina problems — and how to fix them
Pinnate Primulina (Primulina pinnatifida) 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.
Crown and petiole rot
Caused by water pooling in the rosette or on the leaf bases; always water at soil level and ensure the pot drains freely — soggy conditions collapse the crown rapidly.
Mealybugs
White cottony clusters appear in leaf axils and on flower stalks; isolate the plant immediately and treat with a cotton swab dipped in 70% isopropyl alcohol, followed by a neem oil spray.
