Liquid Mulch grade 1-4

General description

 Liquid Mulch (LM) is a concentrate that is diluted before use.  It is poured onto the soil and dries to form a durable, permeable film that allows the plant to breathe and also allows water to reach the roots.

The dry LM film serves several purposes: 1) New weed seeds that fall onto the surface do not germinate because they remain dry.  Often, they simply blow away in the wind. 2) Water is preserved in the soil. On average watering can be extended by about three days. This is particularly important when delivering plants by truck or in dry environments. 3) Pests are reduced because they cannot cross from the soil to the plant and vice versa. 4) LM binds to the soil, holding it in place and preventing soil erosion.

Existing plants are not affected and grow freely. The grade and amount of LM must be carefully chosen for seeds planted in the soil under the LM film to germinate and grow freely.

Liquid Mulch is available in several grades.  They are specifically formulated for the needs of each type of application.  For example, there is a grade for landscaping, city parks, greenhouses, nurseries and railways.  LM spreads easily over the soil and binds both with the plant stem, soil and pot (or edging), leaving no spaces.  It is a proven cost effective solution.


Liquid Mulch is completely natural.  It is made from corn, potatoe, wheat, soy and cellulose products.  It will degrade naturally in about 3 to 8 months depending on the amount that was applied and depending on the weather.  The LM Film will last longer during dry seasons and will degrade faster during wet seasons.
