In 10b here. You can grow either. Determinate only grow to size, produce fruit then die off. You would grow them in succession to get get tomatoes all season. Indeterminate tomatoes require space as the plants just keeps growing [kinda like a vine] while we have long days of sunlight. Better to decide what type of tomato fruit you want [paste, slicer, etc...].

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

My tomato plants in zone 10b (Los Angeles, CA) still continue to develop new flowers and grow a lot of new fruit. It seems like it is recommended to remove the plants at the end of the growing season... but how do I know when that is?

It is probably an indeterminate variety (will keep growing), they can keep growing if you fertilise and water them. Determinate varieties only grow so high and most of the tomatoes ripen at the same time. Depending on what your seasons are like you could keep growing it. Or if you have produced a good crop and need the ground for another crop soon pull it out and ready the ground for the next crop or season.

Can you grow tomatoes in the winter (Zone 10a)? Are there certain varieties better suited for winter months here?
23 Oct 20, colleen (USA - Zone 10b climate)
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)

When is the best time to grow tomatoes in zone 10A?

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
