These deceptively simple tomato plant surrounds will produce healthier, more productive tomato plants with less effort from you. When planting, just slip an automator around the stem of each seedling to suppress weeds and protect against cutworms. Perforated cones direct water to the root zone. Bright red color triggers a natural plant protein that makes tomatoes mature faster and produce more fruit. Easy to use, but provides a big boost to your tomatoes.
