Zone 6b Planting Schedule

All Zones Zone 6b Save Garden
Last spring frost: Apr 25th
First fall frost: Oct 16th
Growing season: 174 days

Action Plan: June in Zone 6b

Expert Note

In June, keep soil evenly moist and mulch to reduce heat stress and weed pressure. Watch for aphids, flea beetles, and tomato hornworms; use row cover early and inspect leaves weekly. Water at the base in the morning to limit fungal issues.

Seed & Soil

Get warm-season starters in: transplant Tomato and Bell Pepper once nights stay reliably warm, and set out Zucchini and Cucumber with direct sow where soil is hot. Add Basil after the soil warms for best growth.

The Harvest

Harvest frequently from Lettuce and Spinach to stay ahead of bolting as temperatures rise. Pick Green Beans and Radish at peak tenderness, and keep harvesting Zucchini every few days to maintain production.
