What To Plant In July In Southern California

This guide will dig into what you can sow during this vibrant mid-summer month across the various USDA hardiness zones that define Southern California.

 

Vegetables To Plant

Vegetable gardening can be exceptionally rewarding, and July provides a great window for planting warm-season crops in Southern California’s various USDA zones. The most common zones you’ll encounter in Southern California are USDA Zones 9 and 10. Here are ten vegetables to consider planting this month.

 

Tomatoes

Planting Tomatoes in the Garden

Tomatoes thrive in the warm sun and well-drained soils of Southern California. In July, you can still plant heat-tolerant varieties, which will produce an abundant summer crop. Choose indeterminate types like ‘Sun Gold’ or ‘Sweet 100’, which can bear fruit until frost. They prefer daytime temperatures over 70°F but can handle heat stress if adequately watered. Be mindful to provide trellising support, and anticipate a rich harvest as the summer progresses.

 

Peppers

Hydroponic Bell Pepper Yield Per Plant

Like tomatoes, peppers are heat-lovers that flourish in Southern California’s warmth. July is ideal for sowing both sweet and hot pepper varieties, such as ‘California Wonder’, ‘Jalapeño’, and ‘Serrano’. These plants prefer soil temperatures of at least 65°F and can withstand the mid-80s to 90s without issue, provided they receive regular watering. Note that over-fertilization can lead to leafy growth at the cost of fruit yield, so use a balanced fertilizer sparingly.

 

Cucumbers

Planting Cucumbers in a Garden

Cucumbers are another fantastic warm-weather vegetable that can be planted in July. Opt for fast-growing varieties like ‘Marketmore’ or ‘English Cucumbers’. These plants thrive in the summer heat, requiring temperatures of 70°F to 90°F to germinate effectively. With their sprawling growth habit, they benefit from trellising, which allows healthier air circulation and simplifies harvest. Regularly monitoring for pests such as cucumber beetles is vital for maintaining healthy plants.

 

Squash

Both summer and winter squash can be seeded in July. Summer squash varieties such as ‘Zucchini’ and ‘Yellow Crookneck’ are especially productive. They favor soil temperatures of 60°F to 90°F and can flourish under Southern California’s sun. Ensure consistent moisture, particularly during the fruiting stage, for optimal growth. Winter squash, like ‘Butternut’, can also be started; however, be prepared for longer maturation times since they are harvested later in the season.

 

Beans

How to Grow Beans at Home

July is prime time for planting various types of beans, such as bush beans (e.g., ‘Blue Lake’) and pole beans (e.g., ‘Kentucky Wonder’). Beans thrive in well-drained soil and prefer full sun with temperatures above 70°F, making them perfectly suited for Southern California’s climate. Moreover, beans fix nitrogen in the soil, enriching it for subsequent crops, which is beneficial for any crop rotation strategy post-harvest.

 

Carrots

Planting Carrots

Root vegetables, such as carrots, can be sown in July, particularly short varieties like ‘Little Finger’ or ‘Nantes’, which thrive in sandy soil. Carrots require cooler soil temperatures to germinate effectively, ideally around 55°F to 75°F. If planted in heat, they may become deformed. Be sure to keep the soil consistently moist for best results, and perform thin planting to avoid overcrowding.

 

Basil

While often considered an herb, basil can function as a green in your garden and is perfectly suited for July planting. Varieties like ‘Genovese’ and ‘Thai’ thrive in hot climates and love well-drained soil. Basil demands consistent moisture and benefits from regular harvesting, which encourages bushier growth and prevents flowering. It’s a perfect companion for tomatoes and is great for culinary uses.

 

Radishes

Radish Care & Harvest

Radishes are quick-growing and can be interplanted with slow-growing crops, making them ideal for July. Varieties like ‘Cherry Belle’ and ‘Black Spanish’ can thrive even as summer temperatures peak. Plant the seeds directly in well-tilled, fertile soil, ensuring enough water to prevent them from becoming tough and bitter. Radishes are generally ready for harvest in about 25 to 30 days.

 

Melons

How to Grow Melons

Melons, including cantaloupe and watermelon, can be planted in July for a ripe late-summer harvest. Varieties like ‘Honeydew’ or ‘Sugar Baby’ have shorter growth cycles, allowing you to harvest in late summer even when planted in July. They thrive in hot temperatures, requiring full sun and consistent moisture. They do need ample space to sprawl, making them best suited for expanded garden beds.

 

Sweet Potatoes

Sweet potatoes are best started in July in Southern California. These tubers prefer warm soil (70°F or above) and thrive in sandy loam soils that drain well. Opt for slips (young plants) rather than seeds, as they tend to establish quickly. Water these plants consistently, as they prefer about 1 inch of moisture weekly, to support their growth until harvest late in the fall.
