Zone 1b Planting Schedule

Last spring frost: Jun 1st
First fall frost: Aug 1st
Growing season: 61 days

Action Plan: June in Zone 1b

Expert Note

In June, keep soil evenly moist and mulch to hold moisture and suppress weeds. Watch for early-season aphids and flea beetles on tender growth; use insecticidal soap if needed. Ensure good drainage to prevent rot during humid spells.

Seed & Soil

Get warm-season starts and transplants in while nights are staying mild: Tomato and Bell Pepper for steady summer harvests, plus Zucchini and Cucumber for quick, high-yield production. Direct sow Basil after the soil warms for reliable germination.

The Harvest

Harvest ongoing fruit and keep plants producing: pick Bluecrop and Blueray as berries ripen, and collect Boysenberry frequently to prevent overripening. If you have early apples, take Precoce D'Argenteuil and Pink Lady promptly for best flavor and texture.
