Troubleshooting
Greek Bush Basil problems — and how to fix them
Greek Bush Basil (Ocimum basilicum var. minimum 'Greek') 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.
Crowded, mildew-prone centre
The dense globe traps humidity. Thin interior growth occasionally and keep airflow good to prevent fungal problems.
Drying out in small pots
Compact root balls in small containers dry fast in heat; check daily in summer and water before the leaves wilt.
Cold sensitivity
No frost tolerance; foliage blackens below about 10°C. Keep warm and move indoors before frost.
Loss of compact form
Too little light makes the neat dome stretch and open up. Give full sun or a bright window to keep the tidy shape.
