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)

Hi there, can you please tell me what the best fertiliser to use on my tomatoes and how often, Kind regards Alex..

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.

Tropical climate - plant tomato seeds May, transplant June and July. Your soil mix is very porous, it would dry out very quickly especially in hot Darwin. And with watering it would leach out the fertilisers. With your soil mix you probably needed to water 3-4 times a day. The wet season probably leached all the Dynamic Lifter out of the soil. Ok- potting mix has a lot of wood in it. Material like this grabs the nitrogen before the plant does. Compost would do the same if it is not completely broken down. Here is what I do, sub tropical, in the fallow season Nov to April, I dig/turn my soil over adding grass clippings, shrub trimming etc mulched with the mower. With normal rain it will keep this moist and help break down the grass etc. You can add a little D Lifter. By late April /early May after the wet season you should have some good friable soil (depends what the original soil was like). You could add some more compost if you like and maybe manures, about 3-4 (?)
