Spider/Muriel

I had been wondering too, perhaps for too long. My tomator plants which are still in the house because of the time it is taking to get our green house up, are now about 3 feet tall! There are some toms, but I think it have left it too late!. Can anyone tell me what to do with 3 foot plants with about 4 or 5 shoots (sorry trusses) please...

Thanks.
