Is there such a thing in the US other than the earth box I read about? Here in England, where the tomatos usually have to grow in a green house or between May and September (frost last night, still can be frost in May, but zone 8! for winter low temps!), they sell flat plastic bags of compst mix you cut a few planting holes in the top, poke a few drainage holes side/bottom, and then tuck a cuke or tomato or pepper plant into the holes (1 every foot or two of bag). After always learning don't ever crowd tomato plant roots it's been so wierd to transplant a tom maybe shoving root in sideways from hole and bending it up out of hole, and getting great harvest with several feet tom growing up string in greenhouse, and then year's end composting the bag contents which is chock full of roots. Can also be grown in this bag on the stone patio- bag and stone warm up better than dirt in garden.
