Hello! I have ten dwarf, determinate, heirloom tomato plants with expected height of 36-48"growing in pots, in an 8x10 greenhouse. They are nearly 56" and producing fruit. However, they have outgrown their pots with roots showing on top of the soil and some have roots growing out of the bottom of the pot. The tomatoes are just starting to grow, they are about the size of a quarter. I've been adding more soil to the top of the pots when the roots are exposed. Is it worth trying to transplant them into a bigger pot and then moving them outside? They are so big I don't think I could do it without damaging them and then they would lose the protection of the greenhouse.
