Seedling
3-4 weeksSmall green cotyledons emerge 7-10 days after sowing; true leaves develop within 2 weeks
Maintain consistent moisture and 70-75°F soil temperature; provide bright light 12-16 hours daily; thin to strongest seedlings if sown directly
Vegetative Growth
2-3 weeks after transplantingPlant develops multiple stem segments, leaves, and establishes sturdy base; grows 4-8 inches tall
Harden off transplants gradually before planting outdoors; provide support with cages or stakes; pinch off lower suckers to improve air circulation
Flowering
2-3 weeksYellow flower clusters (inflorescences) appear at leaf axils; determinate type flowers prolifically over short period
Maintain consistent watering; avoid excessive nitrogen which delays fruiting; ensure pollination through gentle vibration or bee activity; may require hand-pollination in cool conditions
Fruiting & Maturation
3-4 weeksGreen fruits develop rapidly, swelling to 6-8 oz; gradually transition from green to pink to bright red at maturity
Remove some foliage cautiously to allow sun exposure to developing fruits; continue consistent watering; mulch heavily; support heavy fruit clusters; monitor for blossom-end rot (add calcium if needed)
Harvest
2-3 weeks of peak harvestFruits reach full red color and yield slightly to gentle pressure; flavors are at peak
Harvest fully ripe fruit for best flavor; pick regularly to encourage continued production; determinate types produce most fruit in concentrated window; use pruners to avoid plant damage

Harvest Tips
Alma Pötschke is a determinate variety, so most fruit ripens within 2-3 weeks in mid to late summer. Pick tomatoes when fully red and slightly soft to touch for best flavor. Harvest regularly to encourage continued production. Can pick at breaker stage (first blush of color) and ripen indoors if needed. Determinate tomatoes concentrate their harvest, making them ideal for canning and preserving.
