Water less, spray less, and quit weeding altogether when you put these protective mulching trays around your plant. Fill the tray with water and let it soak through the drainage holes, deep into the surrounding soil -- with no water wasted on pathways or between plants, and less risk of wilt encouraged by wet leaves. The red color stimulates growth while the tray provides mulching action. You'll get more consistent soil moisture, nice uniform produce, and more of it -- up to 20% more Tomatoes on each plant! Protects all kinds of vine crops from soilborne diseases and crawling insects (including cutworms), plus helps conserve water during dry spells. Sold as a set of three.
