July Planting Guide for San Diego Gardens: Raised Beds, Containers & In-Ground
In July, San Diego gardeners can focus on warm-season crops and heat-tolerant vegetables in raised beds, containers, and in-ground gardens. This is an ideal time to plant heat-loving vegetables and herbs while preparing for fall crops by starting seeds indoors. Avoid sensitive cool-season plants that struggle in summer heat.

Lettuce prefers cooler temperatures, so it's best to start it indoors in July and transplant in early fall when temperatures drop.
How often should I water raised beds in July?
Water raised beds deeply about 2-3 times per week, adjusting based on heat and soil moisture to prevent drying out.
Are tomatoes suitable for container planting in July?
Yes, tomatoes thrive in containers during July if they receive full sun and consistent watering.
What is the best way to protect seedlings from heat stress?
Provide shade during the hottest part of the day and keep soil evenly moist to reduce heat stress on seedlings.

Begin starting fall crop seeds indoors in mid to late July to transplant outdoors by late August or early September.
