August Planting Guide for Los Angeles Gardens: Raised Beds, Containers & In-Ground

In August, Los Angeles gardeners can focus on planting cool-season vegetables and herbs that thrive as temperatures gradually cool. This is an ideal time to sow leafy greens, root vegetables, and start indoor seedlings for fall transplanting. Raised beds, containers, and in-ground gardens all benefit from consistent watering and shade during the hottest days.
