All Zones Zone 5a Save Garden
Last spring frost: May 8th
First fall frost: Sep 30th
Growing season: 145 days

Action Plan: June in Zone 5a

Expert Note

In June, keep soil evenly moist and mulch to reduce swings in temperature. Watch for aphids, flea beetles, and early blight on warm-season plants; remove damaged leaves and use row cover early when pressure is high.

Seed & Soil

Direct sow heat-lovers like Green Flesh Honeydew and Patio while soil is reliably warm. Transplant sturdy starters such as Early Girl and Regal F1, and keep herbs like Cinnamon Basil going with fresh sowings for steady harvest.

The Harvest

Harvest frequently from Bibb and Butterhead Bibb to keep heads tender. Pick snap-ready Blue Lake 274 and cut leafy greens like Spinach and Bloomsdale Long Standing before they bolt in the heat.
