What is the primary use of straw bales in landscaping?

The primary use of straw bales in landscaping is for soil erosion control. Straw bales are effective in stabilizing soil and preventing erosion, particularly on slopes or areas prone to runoff. When properly placed, they form barriers that slow down water flow, allowing sediment to settle and reducing the risk of soil loss. Additionally, straw bales help retain moisture in the soil and can promote healthy vegetation growth by providing support in an erosion-prone area.

While straw bales can contribute to other functions such as thermal insulation, weed suppression, and even water retention, their most recognized and practical application in landscape management is specifically aimed at controlling soil erosion. This characteristic makes them valuable in various landscaping projects and in areas where soil stability is a concern.
