How to Grow Grape Tomato
Solanum lycopersicum
Grape tomatoes are a popular warm-season variety prized for their elongated shape and sweet flavor. Gardeners grow them for their prolific yield and suitability for fresh eating or drying.
Starting Grape Tomato: indoors or direct sow?
🏠 Start indoors 8 weeks before your last spring frost, then move the seedlings outside.
Transplant seedlings outdoors only after all danger of frost has passed and soil temperatures are consistently warm.
Soil, care & harvest
Prepare loose, fertile soil with a pH between 6.0 and 6.8 to ensure healthy root development. As a warm-season crop, you must wait until after the last spring frost when the soil is fully warm before planting outdoors. Start seeds indoors about 6-8 weeks prior to the expected frost date. Sow seeds ¼ inch deep; germination typically takes 7 to 14 days.
Space plants 18 to 24 inches apart in full sun, providing at least six hours of light daily. Install stakes or cages early for support as these vines can reach heights up to 10 feet. Maintain consistent moisture with deep watering and apply mulch to retain soil humidity. Feed regularly during the fruiting stage to sustain high production levels.
Watch for tomato hornworms, aphids, spider mites, and whiteflies; use insecticidal soap or hand-picking for control. Prevent early and late blight by ensuring good air circulation and avoiding overhead watering. Harvest fruits approximately 60 days after transplanting when they reach full color and slight softness.
