📏

Spacing: 12-18 inches apart for container growing; 18-24 inches for in-ground beds inches

📅

Days to maturity: 50-65 days from transplant to first ripe fruit

🌱

Planting depth: Plant transplants at same depth as nursery pot, or bury stem up to first true leaves to encourage stronger root development

Soil

Type: Well-draining loamy soil rich in organic matter

pH: 6.0-6.8

Amendments:

compost aged manure perlite or coarse sand for drainage balanced fertilizer or tomato-specific formula

Growth Stages

Seedling

2-3 weeks

Tiny plants with seed leaves and 1-2 true leaves appearing; very delicate and light green

Keep soil consistently moist but not waterlogged. Provide bright light 14-16 hours daily under grow lights or sunny window. Maintain 70-75°F temperature. Fertilize weakly with diluted liquid fertilizer after first true leaves appear.

Vegetative Growth

3-4 weeks

Plant develops 4-6 true leaves and begins branching; stem thickens and roots establish

Maintain 6-8 hours of direct sun or strong grow lights. Harden off seedlings gradually over 7-10 days before transplanting outdoors. Keep soil moist. Begin stronger fertilizing regimen once established.

Flowering

3-4 weeks

Small yellow flowers appear in clusters; plant reaches near-mature height of 12-18 inches with dense foliage

Ensure consistent watering and full sun exposure. Maintain steady temperatures 65-80°F. Feed with balanced or slightly phosphorus-heavy fertilizer to encourage flower production. Hand-pollinate if indoors or in containers with limited pollinator access by gently shaking flowers.

Fruiting

4-6 weeks

Marble-sized green fruits develop from flowers; gradually enlarge and change color from green to red over 20-30 days

Continue consistent watering and feeding. Provide sturdy support with stakes or small cages as fruit weight increases. Pinch off excess side shoots to direct energy to fruit ripening. Reduce nitrogen fertilizer in favor of potassium and phosphorus.

Harvest

6-12 weeks (or until frost)

Fruits fully red, glossy, and sweet; plant continues producing successive flushes of flowers and fruit

Harvest ripe fruits regularly to encourage continued production. Remove any diseased or damaged foliage. Continue watering and light fertilizing. Extended season in warm climates; frost kills plants in cold zones.

Harvest Tips

Pick fruits when fully red and slightly soft to touch for maximum sweetness. Mini Mark produces continuously, so harvest regularly to encourage more blooms. Fruits can be picked at pink stage and ripened indoors if needed. Morning harvest yields crispest fruits. Use gentle twisting motion or small pruning shears to avoid damaging vines.

Fun Facts

🌱 Mini Mark was specifically bred by the University of Florida to be the world's smallest determinate tomato variety, making it perfect for space-conscious gardeners and container growing.
🌱 Despite their tiny size, Mini Mark plants can produce 100+ cherry tomatoes per plant in a single season under good growing conditions.
