You could try growing normal cordon toms, and pinch out the tops after the first truss, allowing the side shoots to develop as a low plant. Because we have plenty of room on 'the allotment, we grow masses of plants, and of course, some of them don't get noticed as much and stay quite low, growing quite happily with a couple or three main stems and some productive side shoots as well! As long as there aren't more than four or five trusses, they're just fine
Greenhouse toms are for early crops, outside ones for the 'mains' here. A chum still had some 'Mountain Magic' going in November!
