This fibrous wood mulch makes a very dense layer
that is great for controlling weeds and keeping the soil
cool and moist - ideal conditions for plant root development.
Gorilla Hair mulch is expensive at about twice the cost of
recycled wood chips from Miramar Nursery, but is looks great.
Here is a website for info on buying it in San Diego;
