Tomato Leaf Curl

Rolling of Tomato leaves usually results from one of four things: persistent wind, heat, herbicide damage, or virus. If it’s wind, put up a windbreak. If it’s heat, just keep the plant well watered. If it’s a virus, leaves will eventually show a pattern of spotting or widespread discoloration. If all of your other varieties are fine, it is possible this variety does not have good root characteristics or may suffer more easily from conditions that don’t cause the same response in other tomato plants.
