Expert Note

August in Zone 2b is still warm enough for steady growth, but nights can cool quickly. Keep soil evenly moist, mulch to limit evaporation, and scout for late-season aphids and caterpillars; use row cover if damage appears.

Seed & Soil

Direct sow quick, heat-tolerant standbys like Green Basil and Arugula while soil is warm, and transplant or start Broccoli for a fall push. Add Carrot and Beet where you can keep moisture consistent for even germination.

The Harvest

Harvest regularly from Potato and Tomato as they ripen, and pull mature Onion when tops begin to fall. Keep picking Zucchini and Cucumber every few days to maintain production and prevent overgrown fruit.
