Chef’s Trio Basil

Light requirements: Full sun is ideal, but plants can grow in part shade.

Planting: Space 8 to 18 inches apart, depending on type. (Read the stick tag that comes with the plant for specific spacing recommendations.)

Soil requirements: Plants grow best in rich, moist but well-drained soil with a pH of 6.0 to 7.0. Work organic matter into soil before planting to add fertility and improve moisture retention. In containers, use premium quality potting soil.

Water requirements: Keep soil consistently moist through the growing season. Add a mulch layer to slow water evaporation from soil. In containers, water whenever the top inch of soil is dry.

Frost-fighting plan: Basil is very frost-tender and damaged by temperatures below 40º F. Use a frost blanket to protect newly planted seedlings from late spring frosts or prolong the fall growing season.

Common issues: Pinch flower buds to keep plants from bolting. Once flowers form, leaf flavor changes. Pests to watch out for: aphids, slugs, Japanese beetles, and earwigs. Fungal diseases sometimes occur in humid climates, and root rot is common in poorly drained soil.

Growing tips: Pinch or prune basil plants as they grow to promote branching and bushiness. Never cut into the woody parts of a stem; plants won’t resprout.

Harvesting: Pick leaves at any point in the growing season. Choose individual leaves, or snip leafy stems to the length you desire.

Storage: Cut basil stems and place in water like a fresh bouquet. They’ll last for weeks, provided you remove any leaves below the water line and change water regularly. Never place basil in the refrigerator; the cold air damages leaves. Preserve basil by freezing or in herbal vinegars.
