Growing Conditions

☀️

Sun: Full sun, minimum 6-8 hours daily; 8+ hours preferred for maximum fruit production and sweetness

💧

Water: Consistent, deep watering 1-2 inches per week; water at soil level to avoid foliage diseases; more frequent during fruit development and hot weather; mulch to retain moisture and regulate soil temperature

📏

Spacing: 24-36 inches

📅

Days to maturity: 75-85

🌱

Planting depth: Plant seeds 1/4 inch deep; bury transplant stems up to first true leaves for stronger root system

Soil

Type: Well-draining, fertile loamy soil rich in organic matter

pH: 6.0-6.8

Amendments:

Compost aged manure bone meal balanced fertilizer (10-10-10) calcium (to prevent blossom end rot)

Growth Stages

Seedling (0-4 weeks)

3-4 weeks

Tiny seedlings with cotyledons emerge, then develop first true leaves; plants are delicate and pale green

Keep soil consistently moist but not waterlogged; provide 14-16 hours of bright light daily; maintain 70-75°F temperature; avoid damping off with good air circulation

Transplant/Vegetative (4-8 weeks)

3-4 weeks

Plants develop multiple sets of true leaves; stems strengthen and become more robust; ready for potting up or hardening off

Pot up into larger containers when 2-3 inches tall; harden off gradually by exposing to outdoor conditions; begin low-nitrogen feeding if not in rich potting soil

Establishment/Early Growth (post-transplant to 6 weeks)

4-6 weeks

Plants reach 12-24 inches in field; strong stems develop, foliage becomes dark green and abundant; root system establishes deeply

Install sturdy stakes or cages early to prevent root damage later; prune lower leaves once established for air circulation; provide consistent water and balanced fertilizer every 2 weeks

Flowering & Fruiting (6-12+ weeks)

8-10+ weeks

Yellow flower clusters appear and develop into small green fruit; fruits rapidly enlarge to full size, turning deep red as they mature

Maintain consistent watering to prevent cracking and blossom end rot; switch to higher-phosphorus fertilizer; prune suckers on indeterminate varieties to direct energy to fruit; support heavy fruit branches with ties or slings

Peak Production & Harvest (10-16+ weeks)

6-10+ weeks

Large beefsteak fruits reach 1-2 pounds each, develop deep red color with rich flavor; plant continues producing new flowers and fruit until frost

Harvest ripe fruit regularly to encourage continued production; remove any diseased leaves; continue deep watering and fertilizing; toward season end, prune excess foliage to hasten ripening of remaining fruit

Harvest Tips

Pick fruit when fully red and slightly soft to the touch, typically 70-85 days from transplant. For best flavor, harvest in morning after dew dries. Leave stem attached if possible. To ripen end-of-season green tomatoes, pick before first frost and store at room temperature away from direct sun. Ripe beefsteaks are best used within a few days but can be stored at room temperature (not refrigerated) for up to a week.
