Horta-Sorb® MD is a medium-grade water absorbing granule designed for use in soil to enhance root zone moisture retention. These gel polymers absorb hundreds of times their weight in water and slowly release it, creating a steady water supply for plants while significantly reducing irrigation frequency—by as much as 50%.
When added to planting mixes, soils, or transplant amendments, Horta-Sorb MD granules help maintain consistent root hydration. This leads to better plant establishment, less stress during dry periods, and overall improved plant health. The medium granule size makes it ideal for use in a wide variety of professional and commercial growing environments.
Originally used as a bare root dip in forestry, Horta-Sorb MD has been widely adopted in nurseries, greenhouses, landscaping, agriculture, and hydro-mulching. It is also used in unconventional ways, such as ice packs for shipping cut flowers and fresh seafood, due to its water-holding capability.
Whether you’re growing in containers, planting in dry climates, or reducing labor and water costs, Horta-Sorb MD water absorbing granules offer a versatile, effective solution for long-term plant hydration and moisture control.
