Zone 3a Planting Schedule
Last spring frost:
May 15th
First fall frost:
Sep 1st
Growing season:
109 days
Action Plan: May in Zone 3a
Expert Note
May in Zone 3a warms up, but nights can still dip. Keep transplants well-watered and mulch to stabilize soil moisture; side-dress with compost or a light nitrogen feed. Watch for flea beetles and early aphids, and remove any diseased leaves promptly.
Seed & Soil
Get warm-season starts in the ground as soon as nights are consistently mild: Tomato and Bell Pepper benefit from steady moisture and protection from cool snaps. Direct sow quick, heat-tolerant crops like Green Beans, Zucchini, and Cucumber while soil is warming.
The Harvest
Harvest apples and berries regularly to prevent overripening: pick Honeycrisp, Golden Delicious, and Red Delicious as they reach full color and ease off the branch. Continue picking Boysenberry and Marionberry every few days for best flavor and yield.
