Made of double-layer polyester fabric with drip-irrigation lines running through it, the Weed Free Garden Watering Blanket smothers weeds while watering the plants throughout the growing season. To use, one simply rolls it out over the tilled garden bed, stakes it down, cuts holes to set the seedlings, applies fertilizer, and hooks up the watering hose. According to the manufacturer, the UV-protected blanket saves up to 75% on water usage while encouraging earthworm and soil microbe activity that results in more disease resistance and better yields. Lasting from 5 years (if left in open sunlight) up to 20 years (if covered with several inches of mulch), it's available in 100- to 1,200-foot rolls in widths from 2 to 10 feet or as a ready-to-go kit for an 80-square-foot garden.
