Perlite is a versatile soil amendment and growing medium component that can be used alongside mulch films to improve soil structure, drainage, and root health in gardening and landscaping applications. While perlite is not applied directly to mulch films, it can complement mulching practices to create optimal growing conditions for plants.

When used as a soil amendment, perlite promotes healthy root development. This can be particularly beneficial when growing plants beneath mulch films, as it helps plants access nutrients and water more efficiently.

While mulch films are often used to conserve soil moisture, adding perlite to the soil can further enhance water retention for plant roots. Over time, soils can become compacted, limiting root growth and water infiltration. Perlite, when mixed into the soil beneath mulch films, helps reduce compaction, ensuring better soil structure for plants.
