Frequently Asked Questions

What pest or disease most often affects Ocimum basilicum (sweet basil), and how do I treat it?

Sweet basil is especially prone to downy mildew (often showing as yellow patches on top leaves with gray-purple growth on the underside) in humid conditions. Remove and discard affected leaves, improve airflow, and avoid wetting the foliage when watering; if it’s spreading, use a labeled fungicide for downy mildew on herbs and repeat as directed. Basil can also suffer from aphids—blast them off with water and spot-treat with insecticidal soap if needed.

How often should I water sweet basil during the main growing phase, and what soil moisture level should I maintain?

During active growth, keep the soil evenly moist but not waterlogged—water when the top 1 inch of soil feels dry. Aim for deep watering so moisture reaches the root zone, then let excess drain; basil in soggy soil is more likely to develop fungal problems. In full sun, expect more frequent watering than springtime containers, especially after plants fill out.
