Straw Mulch

HolbrookgeneraloverveiwofStrawMulching0Description
The spreading of a straw mulch over areas previously seeded using the Hydroseed method. The straw is then coated with a slow-setting anionic bitumen emulsion to adhere the straw fibres together and to stop the straw being blown away in light winds.

Suitability
This method is used where fast revegetation of embankments is required, as the straw mulch mat promotes fast germination of seed, and also helps to prevent large volumes of runoff during storms. It usually provides better protection against erosion than does Hydramulch.

Expected Growth
This method achieves the fastest germination.

Relative Cost
This is a more expensive method of revegetation than for Hydramulch, due to the inclusion of the straw mulch, however, it also generally achieves the fastest seed germination.
