Planting & Care

Sow Dark Opal basil seeds indoors 6-8 weeks before the last frost, or directly outdoors after the danger of frost has passed and soil has warmed. Press seeds lightly into the soil surface; do not cover deeply, as light aids germination. Keep the soil consistently moist but not waterlogged. Once seedlings have two sets of true leaves, thin or transplant to 12-18 inches apart. Provide full sun and regular watering for best growth.

For continued harvest, pinch off flower buds as they appear to encourage leaf production. Harvest leaves regularly to promote bushier growth. Basil thrives in warm weather and can be grown in containers or garden beds. Avoid overhead watering to reduce disease risk, and ensure good air circulation.
