Abstract
Abstract A new and improved herb, vegetable, flower, and groundcover sod mat suitable for many landscape applications. The improvement comprises growing either plant seeds, seedlings, plant plugs, rooted cuttings, or root divisions in a planting medium so that the roots of the plant material entangle with a polyolefin sod reinforcement to form a tough, lightweight, flexible sod mat. The sod mat can be produced in many strengths and weights, with many diverse planting mediums, with multiple species of plants. The polyolefin sod reinforcement can contain prodegradants which promote environmental friendliness. Sod mat may be sold in rolls or rectangular mat.
