Stockton Vegetable Planting Calendar
Use Stockton climate patterns to see this month’s garden tasks and crop-by-crop planting windows for the northern San Joaquin Valley and Delta-influenced neighborhoods.
Plant through winter
Broccoli, lettuce, peas, carrots, radishes and leafy greens perform best from fall through early spring.
Use spring warmth
Plant tomatoes, beans, cucumbers, squash and peppers after soils warm, while allowing for cooler Delta breezes and hot inland afternoons.
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
Start indoors
Sow in trays under strong light. The window is timed so seedlings reach transplant size without becoming root-bound.
Transplant or plant
Harden seedlings off for about a week. Perennial crowns, sets and seed potatoes are included in this column.
Direct sow
Plant seed directly into prepared soil. Cool-season crops can begin before frost; heat-loving crops need warm soil.
Last planting
This is the practical end of the selected window—not a guarantee. Variety maturity and unusual weather can move it.

Let Soil Temperature Be the Final Check
Calendar dates start the conversation. A simple soil thermometer helps confirm that the seedbed is actually ready.
