Zone 1b Planting Schedule

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

Action Plan: August in Zone 1b

Expert Note

August in Zone 1b is hot and drying, so keep soil evenly moist and mulch lightly to reduce stress. Watch for aphids, flea beetles, and late-season caterpillars; use row cover early and inspect leaves weekly. Avoid heavy nitrogen late to prevent soft growth.

Seed & Soil

Direct sow White Delite while soil is still warm, and keep the seedbed consistently moist until germination. If transplanting is an option, set plants in the late afternoon to reduce heat shock and water in well. Thin promptly for strong heads and better airflow.

The Harvest

Start harvesting the earliest picks like Adelaide and Afina as they reach size, then continue with Albion and Alderman on a regular schedule. Pick promptly to maintain quality and reduce pest damage; refrigerate soon after harvest.
