Zone 1b Planting Schedule

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

Action Plan: May in Zone 1b

Expert Note

May in Zone 1b is short-season and cool nights are common. Keep soil evenly moist and cover with row cover if temperatures dip; watch for flea beetles on brassicas and aphids on greens. Mulch lightly to stabilize moisture and suppress weeds.

Seed & Soil

Transplant or direct sow hardy cool-season starts like Aspabroc Baby Broccoli, Atlantis Baby Broccoli, and Diablo Brussels Sprout while nights are still mild. Add quick, reliable greens such as Bibb and Bloomsdale Long Standing for early harvests.

The Harvest

Start harvesting Provence and UC 157 as they reach size, and keep checking for peak tenderness. If you have them, pull Millennium and Navaho promptly to prevent over-maturity and quality loss.
