Frequently Asked Questions
What pest or disease most often affects Ocimum basilicum (leaf basil) and what should I do?
Leaf basil (Ocimum basilicum) is especially prone to downy mildew and leaf spots in cool, humid conditions. Keep plants spaced for airflow, water at the soil line, and remove infected leaves; if problems start, use a labeled fungicide for basil or an approved copper-based spray early in the outbreak. Watch for slugs and aphids as well—hand-pick slugs at dusk and spray aphids off with a strong jet of water, repeating as needed.
How can I tell when Ocimum basilicum is ready to harvest?
Harvest leaf basil when plants are 6–8 inches tall with multiple sets of leaves, usually around 40 days from sowing for early growth. Start picking the top leaves and pinch above a pair of leaf nodes to encourage branching; don’t strip more than about one-third of the plant at a time. If you see flower buds forming, harvest promptly and more frequently to keep leaves tender.
