You will do well to plant carrots, peas, radish, turnips, dill, lettuce, spinach, cabbage, broccoli, kohlrabi, and onions. now. These varieties are cold hardy and even if you get some light frost they will be fine.
Chard, beets and parsnips wait another two weeks. These are not quite so cold resistant.
Potatoes wait another month.
See if you can look up [url=https://www.victoryseeds.com/frost/ca.html]frost dates for your location.[/url] Once you are at the average last frost date, you can plant corn, squash and beans. I would wait a week past that to plant cucumbers. Plant out tomato and pepper plants at the same time, a week past av last frost.
