🌾 Sow directly in the garden — Heirloom Beefsteak Mix is not usually started indoors.
Do not start indoors weeks before the last frost; instead, direct sow or transplant seedlings outdoors only after the danger of frost has passed and the soil is warm.
Soil, care & harvest
Prepare loose, fertile soil with a pH between 6.2 and 6.8 before planting. As a warm-season crop, start seeds indoors only after the last spring frost when soil temperatures are consistently warm. Sow seeds about 1/4 inch deep; they typically germinate within 8 to 15 days.
Space plants 36 to 48 inches apart in full sun to ensure air circulation. Install sturdy cages or trellises early, as these indeterminate varieties can reach heights of one to ten feet. Maintain consistent moisture levels and apply mulch around the base to retain water while feeding regularly.
Watch for tomato hornworms, cutworms, aphids, stink bugs, late blight, early blight, fusarium wilt, and bacterial canker. Prevent issues by ensuring good airflow, avoiding overhead watering during wet weather, and removing infected leaves immediately. Harvest ripe fruit 80 to 95 days after planting when the skin yields slightly to gentle pressure.
