🌾 Sow directly in the garden — Super Sweet 100 is not usually started indoors.
Since this is a warm-season tomato sensitive to cold, plant seedlings or direct sow seeds only after the last frost date has passed and soil temperatures are consistently warm.
Soil, care & harvest
Prepare loose, fertile soil with a pH between 6.0 and 6.8 before planting. As a warm-season crop, you must wait until after the last spring frost when the soil is fully warmed to plant outdoors; do not sow early indoors for this specific variety as it is often grown directly in place or started very late. Seeds should be sown about 1/4 inch deep and will typically germinate within 7 to 10 days under warm conditions.
Space plants 18 to 24 inches apart to ensure good air circulation. Provide sturdy support like a cage or trellis since the plant can reach up to 10 feet tall. Maintain consistent moisture by watering regularly, as dry spells cause cracking. Apply mulch around the base to retain water and feed the soil with balanced fertilizer during the growing season.
Watch for tomato hornworms, aphids, whiteflies, and spider mites; inspect leaves frequently and remove pests manually or use organic controls. Prevent early blight, late blight, fusarium wilt, and tobacco mosaic virus by rotating crops and avoiding overhead watering. Harvest fruits 65 to 70 days after planting when they turn fully red and yield easily.
