Broccoli, lettuce, peas, carrots, radishes and leafy greens perform best from fall through early spring.

Warm season

Use spring warmth

Plant tomatoes, beans, cucumbers, squash and peppers as soils warm, before intense inland summer heat.

Restart the cool garden

Begin fall brassicas indoors and prepare beds for direct-sown roots and greens as temperatures moderate.

How to Read This Calendar

1

Start indoors

Sow in trays under strong light. The window is timed so seedlings reach transplant size without becoming root-bound.

2

Transplant or plant

Harden seedlings off for about a week. Perennial crowns, sets and seed potatoes are included in this column.

3

Direct sow

Plant seed directly into prepared soil. Cool-season crops can begin before frost; heat-loving crops need warm soil.

4

Last planting

This is the practical end of the selected window—not a guarantee. Variety maturity and unusual weather can move it.
