I am no expert, but someone here who is in Zone 6 just started seed a couple of days ago. Since you are in Zone 9, I figure you should have a longer window of opportunity. You probably wont harvest until late September/early October, but I assume there are no frosts in southern TX that time of year anyway.

But again, maybe someone from your Zone can give you better info than I.

Do I need to start then inside or can i start them outside? because a while back I started some brandywines inside and they were doing ok. then when I decided to put them outside only 2 out of 12 survived. I figure if i start them outside they will adapt to the heat faster.

How about waiting a bit, and planting for a fall crop? They'd probably do better that way, and you'll get a better crop than during the midsummer heat.

I would make a fall crop, but I haven't ever gardened before so i didn't even know tomatoes grew in the fall. I thought they were a summer plant. but if you could give me some tips as to when to start for a fall crop, and when to put them out.

Thanks
