Soil can be used to hold down the edges of the plastic and prevent the wind's blowing it away. Set plants in slits cut in the material with a knife. If you use strips wider than 3 feet, additional slits may be needed to permit water to enter the soil. The plastic cloth allows good moisture penetration. Rodents can become a problem, particularly if the plastic is laid in the fall.
