Last spring frost: May 13th
First fall frost: Sep 27th
Growing season: 137 days

Action Plan: June in Zone 4b

Expert Note

In Zone 4b during June, keep soil evenly moist and mulch to stabilize temperatures. Watch for flea beetles on young brassicas and aphids on tender greens; use row cover early and rinse off light infestations.

Seed & Soil

Direct sow and transplant heat-lovers now: Marketmore 76 and Parisian Gherkin for steady cucumbers, plus Greek Basil for quick, fragrant harvests. If you want a summer staple, transplant Tomato starts from your indoor set and keep them watered consistently as days warm.

The Harvest

Start harvesting frequently from your cool-season beds: pick Salad Greens and Spinach before they bolt, and cut Bibb or Butterhead Bibb when heads are firm. Snip Garlic Chives and harvest Radishes as they reach size for best flavor.
