About Basil

Basil is the quintessential summer herb — heat-loving fast-growing and endlessly productive when harvested regularly.

Start indoors 4-6 weeks before last frost. Pinch flower buds to keep the plant producing leaves. Never let it set seed. Water at the base — wet leaves cause disease. Loves heat.
