Spray grass or hydromulch is the combination of grass seed, fertiliser, binder (glue), coloured dye, and a mulch product. This mulch can consist of either wood fibre, paper, or straw, and can be alternated to suit the particular job requirements.
All products are combined in a specially designed tank and sprayed onto the ground as a papier mache-type application. The hydromulch protects the seed from the elements and provides additional water-holding capabilities. With adequate watering and care, germination can be achieved in just a matter of days.
At Spray Grass Industries, we predominantly use recycled materials for our hydromulch solutions. For more information or to get your free quote, contact us on 0428 337 555.

Our Standard Hydromulch is widely used across projects in the Darwin and Katherine regions and is composed of cellulose derived from shredded recycled paper. This material provides a clear visual indicator of treated areas, ensuring consistent and accurate coverage. It promotes strong seed-to-soil contact, enhancing germination and establishment, while also assisting with soil moisture retention and protecting seed from animals and environmental influences.
For projects requiring enhanced performance, our Gro-Matt Hydromulch (high-binding mulch) offers a superior solution. This high-binding fibre mix is specifically designed to achieve stronger adhesion to the ground surface, making it particularly suitable for areas prone to erosion. Like the standard option, it provides clear coverage visibility, promotes effective seed establishment, and supports moisture retention while protecting against environmental impacts. Although Gro-Matt delivers improved resistance to erosion and washout, it should be noted that some displacement may still occur during periods of heavy seasonal rainfall.
A hardy, drought-tolerant blend suited to the Top End's harsh conditions. This mix establishes quickly and provides reliable, long-lasting ground cover for a wide range of residential and commercial grassing projects.
Specially formulated for verges, embankments, and disturbed roadside areas, these mixes promote rapid vegetation growth and soil stability, helping to control erosion while restoring a natural appearance to the landscape.
A low-maintenance, dense ground cover ideal for lawns, parks, and recreational areas. Carpet grass tolerates a range of soil types and conditions, making it a popular choice across the Northern Territory.
Using locally sourced native seed, this option supports the recovery of disturbed land while encouraging long-term biodiversity. It's a sustainable choice for mine sites, civil projects, and conservation areas.
