Spraygrass offers 2 types of Strawmulching applications to cater for your projects’ needs. Strawmulching can be applied hydraulically as a premixed solution or blown on and a binder used to tack it in place. The Spraygrass team will work with you to determine which method is best for your project.
The Hydraulically Applied process is similar to Hydromulching using woodfibre however finely chopped straw is used for moisture retention.
The depth of the Strawmulch on drying is generally between 3 – 6mm.
Strawmulch produces excellent yield when sprayed onto a pre-seeded area because it provides seed with a layer of moisture to promote germination.
Even though seed and fertiliser are generally sown separately, Strawmulch can be added to the mix and distributed in a single application.
Spraygrass Strawmulch is packed into convenient, 20kg bags via Enviro Sales.
The Conventional method of Strawmulching involves the blowing of a stream of chopped straw/hay through a mist of heavy-weight binder to a depth of 15mm to 30mm onto an area to be revegetated. The binder Spraygrass uses with the dry blowing process is ideal for site where extra protection against the elements, particularly extremely dry environments, is required.
Dry spraying Strawmulch produces maximum yield when used in combination with Hydromulch as an underlay, further promoting seed germination.
We recommended that whenever possible, areas to be seeded should be topsoiled. Ideally, topsoil should be tested from an authorised laboratory to ensure it has the correct ingredients to facilitate the growth of grass and native seeds. Prior to topsoiling, the soil should be tilled (up to 200mm deep) to further facilitate the highest possible yield. If topsoiling is impracticable, the area should be tilled using a suitable machinery designed for this purpose.
Further yield gains can be achieved by clearing the area of weed growth, large stones or other debris.
Spraygrass recommends a Full Soil Chemistry test to determine if additives are required for the Hydromulch mix or applied directly into the soil.
After Care Maintenance
In most cases natural rainfall will provide adequate seed generation however where possible, adequate water should be applied to ensure a continuous and healthy growth of grass. A general guide, 25mm of water should be applied to all seeded areas weekly. It is important that the mulch be kept moist until germination occurs. After that, sufficient watering must be kept up until a healthy sward of grass is achieved.
