Zone 8b Planting Schedule

Last spring frost: Mar 23rd
First fall frost: Nov 12th
Growing season: 234 days

Action Plan: August in Zone 8b

Expert Note

In August, keep soil evenly moist but avoid waterlogging; mulch helps moderate heat spikes. Watch for aphids, thrips, and pepper fruit drop during hot spells. Use a balanced fertilizer and check undersides of leaves weekly for early pest buildup.

Seed & Soil

Direct sow and transplant heat-lovers while nights stay warm: set out Tomato and Bell Pepper if you have transplants ready, and start quick, productive Basil and Zucchini in warm soil. Keep watering consistent to prevent stress-related leaf curl and blossom drop.

The Harvest

Harvest peppers often to keep plants producing, especially Jalapeño and Poblano when they reach your preferred size and color. Pick Tomato as they ripen and keep Zucchini harvested every couple of days to prevent oversized fruit.
