Expert Note

August in Zone 2a is typically cool and shortening days, so keep soil evenly moist but avoid waterlogging. Watch for late-season pests like aphids and cabbage worms on brassicas; use row cover early and inspect leaves weekly.

Seed & Soil

Direct sow White Delite now for a late-season crop, keeping seedbeds lightly covered and consistently moist until germination. Firm the soil after sowing and thin seedlings promptly so they don’t compete as temperatures cool.

The Harvest

Harvest Adelaide, Afina, and Albion as they reach size and flavor, then refrigerate promptly for best quality. Continue picking Alderman and Alegria on schedule to prevent overmaturity as nights cool.
