Great White Tomato

Start seeds indoors 6 to 8 weeks before your last expected frost date. Maintain soil temperature between 68 and 82 degrees Fahrenheit, and expect germination in 7 to 14 days. Seeds should be sown 1/8 inch deep and kept consistently moist until sprouting. Provide bright light immediately after germination to prevent leggy seedlings.

Harden off seedlings over 7 to 10 days by gradually exposing them to outdoor conditions, then transplant to the garden after all frost danger has passed and soil has warmed. Space plants 24 inches apart with 36 inches between rows. These large-fruited plants benefit from being set slightly deeper than they grew in their containers, as tomatoes can root along buried stems.

Pick fruits when they reach full size and the skin turns from pale green to creamy white, typically 75 days after transplanting. The fruit should give slightly to gentle pressure but still feel firm. Harvest in the early morning when temperatures are cool to maximize shelf life. These large tomatoes are prone to cracking in extreme heat or after sudden heavy rain, so monitor ripening tomatoes carefully and pick them just as they reach peak color rather than waiting for maximum softness.

As an indeterminate variety, Great White Tomato will grow continuously throughout the season. Remove the lowest leaves once the plant is established to improve air circulation and reduce disease pressure. Prune out suckers (shoots that form between the main stem and branches) to direct energy toward fruit production on the main stem and primary branches. Stop pruning 4 to 6 weeks before your first expected frost to allow the plant to finish ripening remaining fruit.
