First fall frost: Dec 9th

Action Plan: June in Zone 9b

Expert Note

In June for Zone 9b, keep soil evenly moist and mulch to reduce heat stress. Watch for aphids, thrips, and hornworms on peppers and eggplant relatives; use row cover on young plants and inspect leaves weekly. Feed every 2–3 weeks with a balanced fertilizer.

Seed & Soil

Direct sow and transplant heat-lovers now: set out Tomato and Bell Pepper for steady summer growth, and keep the beds productive with quick, warm-weather crops like Basil and Zucchini. If you have space, add Cucumber for reliable midsummer harvests.

The Harvest

Start harvesting Tomato as soon as fruits color up, and pick Cucumber frequently to keep vines producing. Harvest Zucchini at a small-to-medium size for best texture, and keep snipping Basil regularly to prevent flowering and maintain leaf quality.
