In this comprehensive guide, we will explore the best vegetables, flowers, herbs, and landscape plants to sow and nurture during July.
Vegetables To Plant
Planting in July offers an excellent chance to grow a variety of vegetables that can thrive during the hot summer months. Here’s a detailed exploration of ten vegetables that can be planted in this warm Californian month.
Tomatoes
Tomatoes are a quintessential summer vegetable, requiring full sun and well-drained soil. In California’s USDA Zones 9 to 11, they can be planted directly into the ground in July. Opt for heat-tolerant varieties like ‘Sun Gold’ or ‘Early Girl’, which can withstand the higher temperatures that California summers can deliver, with a temperature range of 70°F to 90°F being ideal for growth. Ensure consistent watering, especially as the fruits begin to set.
Basil
Basil is a heat-loving herb that pairs perfectly with tomatoes in dishes. Plant basil from seeds or transplants throughout California’s regions in July. It thrives in warm temperatures, ideally between 70°F to 90°F, and should be spaced adequately to promote air circulation. Regular pruning encourages bushier plants and a more robust flavor. Given its preference for well-drained soil and full sun, growing it in pots is a great option for those with limited garden space.
Zucchini
Zucchini is an incredibly versatile vegetable, flourishing in USDA Zones 7 through 10. When planted in July, zucchini seeds can germinate in warm soil and produce fast-growing plants. These likely yield abundant crops, provided they receive adequate water and full sunlight. This squash variety is tolerant of temperatures ranging from 70°F to 95°F. Look out for pests such as squash bugs and ensure proper spacing to prevent disease.
Green Beans
Green beans are a reliable choice for mid-summer planting. In California, they can be directly sown into the ground or started in pots in July. Preferring temperatures between 70°F and 85°F, they grow rapidly and enjoy full sun. Bush varieties are ideal for small spaces, while pole beans can make use of vertical gardening techniques. Regular harvesting promotes continual production, making green beans an excellent choice for home gardeners.
Eggplant
As a warm-season crop, eggplant thrives in July’s heat. Best planted in USDA Zones 9 to 11, they like temperatures around 70°F to 90°F. Eggplants require well-drained soil rich in organic matter. Choose varieties like ‘Black Beauty’ or ‘Italian Long’. Space them properly to avoid fungal diseases and provide support as the fruits develop. Harvest when they are still shiny and firm.
Cucumbers
Cucumbers grow well in the warm summer months and can be planted in July across much of California. They require temperatures between 70°F and 95°F to germinate effectively. Both slicing and pickling varieties are available, so choose based on your culinary needs. Cucumbers thrive in full sun, so a location with at least six hours of light is essential. Use mulch to conserve moisture and keep the soil temperature steady.
Bell Peppers
Bell peppers are another summer favorite that can be planted in July in California. They enjoy warm soil, with optimal growth between 70°F and 85°F. Transplant seedlings in well-drained soil to ensure good drainage and airflow. Use stakes or cages for support, especially as the fruits develop. Varieties like ‘California Wonder’ and ‘Sweet Chocolate’ are excellent choices for growing in the California sun.
Squash
Summer squash varieties, such as yellow squash and pattypan, can be sown in July. They require warmth and will flourish in California’s heat, preferably with soil temperatures between 70°F and 95°F. These plants prefer good air circulation to minimize fungal diseases, so planting at adequate spacing is crucial. Harvest them regularly to encourage further production, as neglecting to pick can lead to overgrown and less palatable fruits.
Carrots
Although typically planted earlier in the season, carrots can still be sown in July in many parts of California. Choose varieties like ‘Nantes’ or ‘Danvers’, which are tolerant to the heat but will need consistent watering as the weather warms. Carrots prefer loose, sandy soil that hasn’t been compacted, making them an excellent choice for raised beds. Cover newly sown seeds with a light layer of mulch to retain moisture.
Lettuce
Lastly, although it may seem counterintuitive, certain heat-tolerant lettuce varieties can be successfully planted in mid-July. California has specific varieties such as ‘Butterhead’ and ‘Loose Leaf’ that can handle the heat while providing a refreshing crunch for summer salads. Plant them in a location that gets partial shade, especially as the temperatures can sometimes soar above 90°F. Be vigilant with watering to ensure crisp leaves.
