Soil Moist Mats: Soil Moist Mats contain water storing polymer woven into a cloth to line baskets and containers. The easy to apply product is designed to reduce plant waterings by 50%. There are six mats per pack. Soil Moist Mats absorb similar to a sponge and hold it in the plant container. Non-toxic crystals are woven into the degradable cloth material. As the soil begins to dry, the mat slowly releases stored water to the soil and the plant's roots over an extended period of time. They reduce plant waterings with less worry and save time and labor. The mats last for several seasons in the soil and are environmentally friendly. The easy to apply mat is ideal for containers, hanging baskets and potted plants for both indoor and outdoor applications.
