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 often should I water Ocimum basilicum during the main growing phase?

During active leaf growth, water leaf basil whenever the top 1 inch of soil feels dry, typically every 1–3 days depending on heat and pot size. Aim for evenly moist soil, not soggy—root rot risk rises quickly if the bed stays wet. Mulch lightly can help stabilize moisture, but don’t cover the crown tightly.
