Zone 4b Planting Schedule

All Zones Zone 4b Save Garden

Last spring frost: May 13th

First fall frost: Sep 27th

Growing season: 137 days

Action Plan: May in Zone 4b

Expert Note

In May, keep soil evenly moist but not soggy; aim for steady germination as nights stay cool in Zone 4b. Watch for flea beetles and cutworms on tender seedlings, and use row cover early. Mulch after plants emerge to stabilize moisture.

Seed & Soil

Start warm-season growth with Tomato and Bell Pepper only after nights are reliably mild, and transplant carefully to avoid stress. Direct sow quick, cool-season standbys like Spinach and Radish while soil is still cool. Add Carrot now for a steady, long harvest window.

The Harvest

Harvest apples and berries as they ripen, especially Honeycrisp, Golden Delicious, and Red Delicious, plus Boysenberry and Triple Crown. Pick frequently for best flavor and to prevent overripe fruit from attracting pests.
