Can you grow tomatoes in the winter (Zone 10a)? Are there certain varieties better suited for winter months here?

I believe I used to live in zone 10a when I lived in Los Angeles (Van Nuys). I *did* manage to grow some tomatoes over winter a couple of times, though I'm not sure it was worth it.

It wasn't worth it because you planted out of season. By the planting guide - plant late winter early spring for a summer crop.

There was more to my reply, recommending varieties (esp Glacier) and alternative approaches, but I'm not sure what happened to it. Maybe I wrote too much info. (Gardenate : Part of the last sentence was missing in your previous reply)

Is the July and August direct sun to much for tomato plants? My plants get to about 12 inches high then the leaves begin to shrivel up. Thanks, Lou

Tomatoes need to be planted deep and then watered deep. A really good watering 3-4 times a week. If your climate is really hot and or dry then maybe plant a bit earlier to avoid the hottest part of summer.

You can grow any tomato your heart desires in your zone! Do you like great big beefy slicing tomatoes? Little cherry tomatoes to eat like snacks? Plum tomatoes to make into sauce or sun-dry? All will do great. You may need to use shade cloth in the hottest months to keep them from scorching (I get 40 percent shade cloth from San Diego Seed Company but Amazon has lots of cheaper ones too). If you try to keep them alive through winter, assuming they don't have blight, you can string incandescent Christmas lights around them and cover with fleece if frost threatens. Indeterminate types are basically perennials and will get huge and possibly survive the winter in your zone, so space may be an issue. I usually have ONE big indeterminate sprawler like a Juliet or a Sungold, and let grow as big as it wants on a tower made of cattle panels, and then grow a number of compact bush tomatoes to get some varied crops for slicing, drying, saucing, etc. In your zone you can constantly start new
