>>1673462Snapped off branches, the ones with leaves, can usually be rooted and planted like cuttings. Trusses that hold fruit won't do that, but if the fruit is already to a certain size it will ripen. Just remove them from the truss and set it out at room temp on the counter. If the tomatoes are wee tiny, they won't ripen in the same manner; they will change color, but not mature.
