Dark-purple Primulina problems — and how to fix them
Dark-purple Primulina (Primulina atropurpurea) 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.
Stem rot from overwatering
The compact rosette form and shallow roots make this species especially prone to stem base rot if the compost stays wet; allow the surface to dry before re-watering and use a very free-draining mix.
Bud drop before flowering
Sudden changes in temperature, cold draughts, or moving the plant once buds are visible can cause buds to abort; keep conditions stable and resist repositioning the pot once flower stalks appear.
