🌾 Sow directly in the garden — Pesto Perpetuo Basil is not usually started indoors.
Direct sow seeds outdoors only after the last frost has passed and the soil is sufficiently warm for germination.
Soil, care & harvest
Prepare loose, well-draining soil with a pH between 6.0 and 7.5 for optimal growth. Since this is a warm-season crop sensitive to cold, start seeds indoors only after the last spring frost date when soil temperatures are consistently warm. Sow seeds about 1/4 inch deep; they typically germinate within five to ten days under these favorable conditions.
Space plants 12 to 18 inches apart in full sun to partial shade to ensure good air circulation. Provide consistent moisture, aiming for one to one-and-a-half inches of water weekly, and apply mulch to retain soil heat and humidity. Feed regularly with a balanced fertilizer to support continuous leaf production throughout the growing season.
Watch for aphids, spider mites, and Japanese beetles; use insecticidal soap or hand-picking to manage infestations early. Prevent downy mildew by avoiding overhead watering. Harvest leaves when plants reach maturity in 60 to 75 days from sowing, snipping stems just above a leaf node to encourage bushier growth.
