Troubleshooting
Purple Ruffles Basil problems — and how to fix them
Purple Ruffles Basil (Ocimum basilicum 'Purple Ruffles') 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.
Colour reversion to green
Insufficient sun or excess nitrogen dilutes the burgundy pigment. Give full sun and feed lightly to keep leaves dark.
Poor germination and variability
'Purple Ruffles' is notoriously slow and uneven to germinate, and seedlings vary in leaf shape and colour; sow extra seed and select the best.
Downy and grey mould
Dense ruffled foliage holds moisture. Space plants, water at the base, and remove affected leaves to limit fungal spread.
Bolting in heat
Flower spikes reduce leaf quality; pinch them off promptly to extend the harvest.
