Spring Planting in Fresno: Soil Temperature Matters More Than Air

Mid-60s air temps in Fresno don't guarantee warm soil. Peas and onions tolerate cool soil; tomatoes, peppers, squash need 70°F soil.

Action Plan

Wait 3–4 weeks for soil to warm, or cover beds with black plastic (damp soil) for 2 weeks.
Start tomatoes, peppers, squash indoors in peat pots.
Onions may take 3 weeks to emerge—be patient.
Direct-sow beans, corn, cucumbers when soil hits 70°F.

Use a soil thermometer; it's the best $10 garden tool.
