Climate matters. This page is a practical baseline. Confirm cultivar, local frost/heat conditions, mature size and regional restrictions before planting.

Growing directions
Sow seed 1/4 inch deep in warm starting mix and keep at 70–85°F until sprouts emerge. Transplant after nights reliably stay above 50°F, burying the stem up to the lowest leaves to encourage a strong root system. Provide a cage or stake for support, and water consistently at the base to reduce the risk of blossom-end rot. Harvest when fruit is fully colored and gives slightly to gentle pressure.
Source and local conditions
Typical planning ranges from OpenPlantDB (CC0). Cultivar, climate, season and growing method can change these values. Confirm the seed label and local guidance before planting.
