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 in deep indoors and harden seedlings off gradually before setting out into cool soil. Feed transplants with a balanced fertilizer at planting and side-dress with nitrogen when heads begin to size. Keep soil moisture consistent, as uneven watering causes heads to split. Harvest when the head feels firm and solid when squeezed; a light frost sweetens the flavor.
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.
