How to Grow Eggplant
Solanum melongena
Eggplants are warm-season favorites prized for their tender, meaty fruit that ranges from glossy purple to vibrant white or yellow. Gardeners grow them for their versatility in savory dishes, soups, and roasts, enjoying the unique flavor profile they bring to summer tables.

🌾 Sow directly in the garden — Eggplant is not usually started indoors.
Direct sow seeds outdoors only after the last spring frost when soil is warm, as eggplants are sensitive to cold and will not survive a hard freeze.
Soil, care & harvest
Prepare rich, well-draining soil with a pH between 5.5 and 6.8 for optimal growth. As a warm-season crop, start seeds indoors only after the last frost date has passed or wait until soil temperatures are consistently warm, as cold kills this plant. Sow seeds about one inch deep; they typically germinate within seven to fourteen days.
Space plants eighteen to twenty-four inches apart in full sun to ensure healthy development. Provide consistent moisture by watering regularly to keep the soil evenly moist without waterlogging. Apply a layer of organic mulch around the base to retain humidity and feed the soil with balanced fertilizer every few weeks during the growing season.
Watch for common pests like aphids, whiteflies, and hornworms, which can be managed by hand-picking or using insecticidal soap. Fungal diseases such as blight may appear in humid conditions; practice crop rotation and ensure good air circulation to prevent issues. Harvest fruits when they reach full size and color, usually taking seventy to eighty-five days after planting.
