Growing Basil
Warmth first, then regular picking
Basil earns its space when it is close enough to pick while cooking. The first decision is timing: a bright spring day does not make cold nights suitable for this tender annual.
Establish a leafy plant
Wait until frost danger has passed. Choose at least six hours of direct sun and soil that stays moist without remaining waterlogged. Maryland Extension gives 12 inches between plants as a starting point; cultivar size and airflow still matter. Pinch growing tips to encourage branching rather than letting one stem run upward.
Harvest and watch
Pick leafy tips as the plant grows. If leaves yellow or decline during humid weather, inspect them before adding fertilizer: basil downy mildew can be involved. Resistant cultivars and uncrowded planting help reduce risk, but do not guarantee a disease-free season.
Learn from this planting
Record planting date, cultivar, first useful harvest and any leaf symptoms. Compare the harvest with the date cold nights returned. That record is more useful next year than assuming every basil variety behaved alike.
