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.

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

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.

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)

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

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?
