Troubleshooting
Primula farinosa problems — and how to fix them
Primula farinosa (Primula farinosa) 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.
Summer drought and heat
Its biggest weakness. Dry, hot summers cause the rosette to shrivel and die. Keep roots cool and moist and shade from fierce midday sun in warm regions.
Winter crown rot
Stagnant wet around the crown in winter rots the plant. Provide sharp drainage and a grit collar so the rosette sits dry while roots stay moist.
Short-lived nature
Often dies after a year or two even when grown well. Let it self-seed or sow fresh seed regularly to maintain a stand.
Vine weevil and aphids
Vine weevil larvae can destroy the roots in pots, and aphids cluster on flower stems. Inspect rootballs when repotting and treat infestations promptly.
