Primula Obconica problems — and how to fix them
Primula Obconica (Primula obconica) 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.
Skin rash from handling (primin allergy)
The leaf hairs secrete primin, which causes itchy contact dermatitis in sensitive people. Wear gloves when handling or repotting, or choose a primin-free 'Touch Me' series cultivar.
Crown and stem rot
Water sitting in the crown or soggy soil rots the plant. Water at the soil or from below, never over the centre, and use a free-draining mix in a pot that drains well.
Short-lived flowering in warm rooms
Heat rapidly ends the display. Keep it cool (ideally 10-18°C) and out of direct heat to extend flowering for weeks rather than days.
Yellowing leaves and bud drop
Caused by drying out, overwatering, or low light. Keep moisture even, give bright indirect light, and avoid letting the rootball dry while in bloom.
