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)

Any general fertiliser will do. Dig a hole 40cm deep and wide. Mix 3 hand fulls of fert into the loose soil. Put 3/4 of the soil back in the hole. Plant the seedling. When plant is 50cm high cut off some of the lower leaves and then fill the hole up with the rest of the soil. Always give a good watering 3 times a week

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.

Hi, I've been planting tomatoes for the last 2 years with success. However, last years fruit were a bit powdery. Any tips on how to stop that? The only thing i add to the soil is compost and occasionally soluble plant food. thanks
