Of course, on a year like this one, we all know heat has not been a real issue, and it would probably work fine to plant cool season crops throughout July. What I am doing now is planting a whole new set of seeds of vegetables to be transplanted in August that will be able to mature for a Fall garden. This includes several lettuces, kale, broccoli, cabbage, radishes, and similar crops trying to choose varieties that are bolt resistant, which simply means they can handle a little bit of heat.
We do have some seedlings still available of flowers, such as alyssum, california poppies and chrysanthemum, to add to your garden to attract beneficial insects. We also have a small collection of herbs including: Common thyme, oregano, sweet marjoram, summer savory, Santo cilantro, parsley, and 3 types of basil (lemon, sacred, and genovese).
