If you’re taking a break this fall and winter after growing summer veggies, then plant a cover crop to enrich and protect your soil as well as to attract beneficial insects. Choose a variety of cool season cover crop seeds, such as flowers, grasses and a legume, for sowing in early fall. See Cover Crops in the Home Garden for more.

Get Ready to Plant California Natives

Fall is the best time to plant most California natives. Cooler weather and (we hope) rain get them off to a good start by helping them grow deep roots – perfect for seeds or transplants. Many nurseries and native plant groups have fall plant sales. In our introductory California Native Gardening web page, you’ll find inspiration and resources to help you get started and get planting. Check our All Events events for seed starting classes for natives and more. Get the basics on planting wildflowers here.

As you're enjoying summer's bounty, it's time to start planning your cool season veggie garden. August and September are the ideal months to seed fall and winter crops such as beets, cabbage, broccoli, peas, kale, spinach, lettuce and much more. Find your microclimate (hot, sunny, foggy) and then consult the appropriate planting calendar to find which vegetables you can start by seed as well as seedlings you can plant.

 

Support Our Local Bees

California is home to over 1600 native bees. These hardworking insects are vital to a thriving ecosystem, but they are under threat from habitat loss, pesticide use and other stressors. To support our native bees, make sure your garden includes a mix of native plants that flower from late winter into the fall. Since a majority of native bees live in the ground, provide areas of bare soil or ground that is lightly mulched or covered with a thin layer of leaves. And do not use insecticides, particularly neonicotinoids. To learn more about some of our native bees, click here. For a list of bee-friendly native plants, visit this site.
