Great White Blue Tomato

The Great White Blue is a mid-season tomato variety with indeterminate growth, perfect for gardeners seeking healthy, nutritious, and flavorful tomatoes. This variety produces firm, tasty fruits and is a rich source of vitamins, minerals, and nutrients.

Organic Tomato Cultivation – Tips for Great White Blue

Sowing: Sow seeds at a constant temperature of at least 20°C, ideally 24°C, from mid-February to late March (about 6–8 weeks before transplanting). Maintain a warm, bright, and humid environment, mist lightly.

Transplanting: After germination, transplant seedlings with 2–4 leaves into pots at 15–20°C. Later plant outdoors at 50 x 80 cm spacing, after April 15 under glass or after the last frost. In northern regions, growing under glass is recommended, but sunny, well-ventilated outdoor sites also work.

Pruning: For indeterminate varieties, prune shoots in the leaf axils to encourage high-quality fruit. Determinate varieties do not require pruning; use mulch and staking.

Care and Disease Prevention

• Tomatoes need warmth and organic nutrients, especially potassium (K).

• Bury part of the stem during planting to promote root growth.

• In northern areas, lightly prune to prevent leaves from touching the soil.

• Water regularly without wetting foliage to avoid powdery mildew.

• Preventively use nettle extract, horsetail decoction, or seaweed powder (lithothamne).

• Pur’Mel 3 fertilizer is highly effective: dilute 10% in water for prevention; for mildew 30% twice per week.

Harvest

This mid-season tomato is ready to harvest about 2.5 months after planting. Ripe tomatoes fall easily from the plant. Perfect for fresh salads, canning, and nutrient-rich meals.
