Zone 10 Planting Calendar

Zone 10 Vegetable Planting and Harvest Chart. Zone 10 has a very long growing season, with frost-free conditions most of the year, which means you can grow both cool-season and warm-season vegetables year-round. The last frost typically occurs around mid-January, and the first frost usually happens in early December, though frost is rare in most of this zone.

Zone 10 Gardening Tips:

Frost Dates: Frost is rare in Zone 10, but if it occurs, it is usually around early December to mid-January. However, frost protection might still be needed for certain crops in colder microclimates.

Year-Round Growing: Take advantage of the frost-free period by planting both cool-season crops (like broccoli, spinach, and lettuce) in the cooler months and warm-season crops (like tomatoes, peppers, and beans) during the warmer months.

Warm-Season Crops: Tomatoes, peppers, cucumbers, and beans can be planted year-round, but they thrive best in spring through fall.

Cool-Season Crops: Cool-weather vegetables like lettuce, kale, and cauliflower can be grown in the winter months when the weather is mild.

Succession Planting: Zone 10 offers a perfect opportunity for succession planting, allowing you to get multiple harvests of quick-growing crops like radishes, lettuce, and spinach throughout the year.

Mulching: Because of the warm climate, use mulch to help retain moisture and cool the soil, especially for crops like lettuce, peas, and carrots.

Watering: Consistent watering is essential for many crops in Zone 10 due to the warm weather. Drip irrigation is a great method for efficient watering.
