Basil (Ocimum spp.) is a tender annual that prefers warm weather and rich soil. It is a popular culinary herb, cut flower, and can be used as a medicinal herb to calm the stomach.
Soil Nutrients and Requirements
Basil needs well drained but moist soil that is highly fertile. It is not drought tolerant, so even moisture levels are important for healthy growth.
Seeding Depth
1/4" deep. Transplanting is recommended; if direct seeding, sow 2-3 seeds per inch and thin to 4-8" apart.
Plant Spacing
Transplanting at 4-8" is recommended; if direct seeding, sow 2-3 seeds per inch and thin to 4-8" apart.
Row Spacing
18"
When to Sow
Start transplants indoors 6 weeks prior to planting out, or direct seed mid-spring through late summer. Basil is very sensitive to cold; use row cover to extend the season. Pinch buds to encourage branching and leaf production.
Harvest
Harvest can begin once plants have become established, by pinching or cutting branches but leaving the plant to continue to produce leaves. A harvest of the full plant should be completed just before the plant starts to flower (flavor is significantly impacted once flowering occurs). Cut the entire plant 4-6" above the ground to promote a second growth.
Storage
Store unwashed at room temperature to avoid browning. Do not store below 50°F.
