Frequently Asked Questions

What pest or disease commonly affects Ocimum basilicum (Greek Columnar Basil), and how do I treat it?

Greek Columnar Basil is prone to downy mildew and leaf spotting in humid conditions, often showing yellowing patches on the upper leaves with a fuzzy gray/purple growth underneath. Remove and discard infected leaves immediately, improve airflow around plants, and avoid wetting the foliage when watering. If it keeps spreading, apply a labeled basil-safe fungicide according to the product directions and stop harvesting treated leaves until the label allows it.

How can I tell when Ocimum basilicum (Greek Columnar Basil) is ready to harvest?

Harvest when plants reach about 8–12 inches (20–30 cm) tall and have formed plenty of pairs of mature leaves, typically around 60 days. Pinch or cut just above a leaf pair to encourage branching, and harvest in the morning when leaves are crisp and aromatic. If you see flower buds forming, harvest again promptly but expect reduced leaf production as the plant shifts to flowering.
