Zone 9b Planting Schedule
Action Plan: August in Zone 9b
Expert Note
In August, keep soil evenly moist and mulch to reduce heat stress. Watch for aphids, thrips, and spider mites on tender growth; use insecticidal soap early. Harvest frequently to prevent bolting and reduce pest pressure.
The Harvest
Harvest hot peppers like Bhut Jolokia Chocolate and Red Bhut Jolokia when fully colored for best heat and flavor. Pull or dig garlic varieties such as Siberian Garlic when tops begin to yellow, and keep harvesting greens like Hill Hardy and Japanese Giant before they get tough.
