Starting From Seed

Start indoors approximately 3–4 weeks before your last expected frost, or direct sow after frost danger has passed and the soil has warmed. Sow approximately 1/4 inch deep in seed-starting mix or a prepared garden bed. Keep lightly moist until germination, typically 7–14 days under suitable conditions.

Provide bright light for seedlings and harden them off gradually before transplanting outdoors. Allow approximately 15–18 inches between mature plants for growth and airflow.

Growing and Care

Choose full sun and fertile, well-drained soil. Afternoon shade can be helpful in very hot climates. Water regularly, especially in containers, without leaving the roots waterlogged. Protect plants from frost and chilly weather.

Pinch growing tips above a pair of leaves to encourage bushy growth. Remove developing flower spikes if your priority is continued leaf production; plants left to flower can also attract bees.

Harvest and Kitchen Use

Begin small harvests when plants are established and approximately 6–8 inches tall. Snip stems just above a leaf pair, leaving several healthy sets of leaves for regrowth. Harvest after the morning dew has dried, and use leaves fresh in pesto, salads, and cooked dishes.

Storage and Seed Saving

For short-term storage, stand freshly cut stems in a glass of water at room temperature. Basil can also be frozen or dried; dry leaves thoroughly before storing to prevent mold.

To save seed, let selected flower heads mature and turn brown. Cut and dry them in a protected, ventilated place, then separate the seeds from the chaff and store in a cool, dry location.
