Italian Large Leaf Basil

Start seeds indoors 6-8 weeks before the last frost date, planting 4-6 seeds per cell at 1/4 inch deep in moderately moist, well-drained potting mix. Seeds germinate in 5-10 days and should be thinned to 1-2 plants per pot once true leaves establish. Harden off seedlings before transplanting outdoors.

Transplant hardened seedlings outdoors after all danger of frost has passed, spacing them 9-12 inches apart in the garden with full sun exposure and well-drained soil.

Direct sow seeds after the last frost date, planting them 1/4 inch deep and 3-4 inches apart in moderately moist, well-drained soil in full sun locations.

Begin harvesting Italian Large Leaf Basil once plants have sufficient foliage, typically around 60 days from sowing, though some sources report earlier harvest possible. Always harvest leaves before the plant flowers to maintain optimal flavor and oil content. Cut stems just above a set of leaves rather than removing individual leaves, which encourages bushier growth. For maximum oil content and flavor, harvest on dry mornings before the heat of the day, and avoid taking more than one-third of the plant at once to prevent damage.

Regular pinching is essential for Italian Large Leaf Basil to maintain bushy growth and continuous leaf production. Pinch off the tallest growth and any flower buds that appear, as flowering causes the flavor to become too strong and reduces leaf quality. Harvest by pinching stems just above a set of leaves, which encourages branching and keeps plants producing. Prune monthly during the growing season, and consider applying liquid nitrogen fertilizer after pruning sessions to support recovery and new growth.
