We had a real hot summeer this year, as such, most of our tomatoes heirlooms and hybreds shut down a little. Our indeterminate grow very tall some 10' to 15' tall but you can prune them to the desired height you want. I think that some heirlooms produce well in the heat the Cheerokee purple does well for us in the heat and our early girl hybred kept putting on tomatoes all summer but the size got very small. Black Cherry does well and our Mo Pink seems to do good in the heat. We grow the vines up on a horizontal cattle pannel that is mounted about 2' above the soil some of our vines grow to the top and them fold over to the ground on the other side. I don't pull our tomatoe plants when they stop producing because I think that they often start putting on again when it finally cools down. Personally we find that growing some heirlooms and some Hybreds work well for us. I like the variety and taste of the heirlooms and the number of tomatoes put on by the hybreds. When canning we mix everything
