Tomatoes Galore

We've been picking out tomatoes for 3 or 4 weeks now and they just keep coming. I have been watering them, of course, seems such a terrible waste to let them shrivel up and die because the hot weather has caused water shortages. We conserve water in other ways and use the water butt until it is empty.
The six plants in the gro-bags were the stronger plants but the more weedy ones were put into the soil. They always seem to do well and the Extra photo shows a lot of green tomatoes so they will be handy when the gro-bag ones start to run out.
