Abstract
Abstract A method of making a mulch composition for mass plantings is disclosed. The process comprises the addition and intimate admixing of a suitable tackifier material under turbulent conditions and elevated temperatures whereby the integrity of the mulch is retained during rainfall or relatively high winds due to attachment of the binder to the mulch material.
