Stm2255 is a determinate tomato that delivers ripe, juicy fruit in 65 to 70 days, capturing that essential moment when summer's first harvest arrives at the table. This cultivar thrives in full sun with moderate water needs and moderate soil pH (5.5 to 7.0), making it accessible to gardeners working with typical garden conditions. As a determinate variety, it grows as a compact bush rather than an indeterminate vine, concentrating its yield for concentrated harvests ideal for fresh eating and preserving.

The speed to maturity is this variety's calling card: ripe tomatoes ready to pick in just over two months from transplant. Determinate growth means you get a concentrated flush of fruit rather than a slow trickle across the season, which appeals to gardeners planning preserves or large fresh meals. The compact habit requires minimal staking and works beautifully in smaller garden spaces or containers where sprawling vines would overwhelm the plot.
Fresh slicing and eating straight from the garden, where the juicy flesh and full ripeness deliver the milestone flavor gardeners anticipate each season. The determinate habit and concentrated harvest also suit those preserving tomatoes through canning or sauce making.

Sow seeds indoors 6 to 8 weeks before your last spring frost, maintaining soil temperature between 70 and 90°F for reliable germination. Keep seedlings warm and under bright light to prevent leggy growth.
Transplant seedlings outdoors after the last frost has passed and soil temperature reaches at least 55°F. Harden off plants by gradually exposing them to outdoor conditions over 7 to 10 days before planting in the garden.
Harvest Stm2255 when fruits are fully ripe and deeply colored, typically 65 to 70 days after transplanting. Pick tomatoes by gently twisting and pulling them from the vine, or use pruning shears to avoid damaging the plant. For the best flavor, harvest when fully ripe rather than picking green fruit. If frost threatens and fruit remains on the vine, you can harvest green tomatoes and ripen them indoors in a cool, dark area away from direct sunlight.
As a determinate variety, Stm2255 requires minimal pruning. Remove only damaged or diseased leaves, and avoid excessive leaf removal that would expose fruit to sunscald. The compact, bushy growth habit naturally concentrates fruit without the heavy pruning demands of indeterminate types.
