Hydroseeding is the spray-on application of a slurry containing mulch, seed, fertiliser, soil amendments and dye. Hydroseeding is used to develop lawns and re-vegetate areas. It’s an innovative method for planting grass and other vegetation. It is preferred for its efficiency in covering large areas quickly and promoting rapid seed germination and growth.

The popularity of hydroseeding is increasing rapidly. Using this method a beautiful lush lawn can be established quickly, at low cost. Landscapers across Australia and New Zealand have found that their customers love hydroseeding, and the prospect of having a beautiful lawn established quickly, at low cost is very attractive to them!

Revegetation and Erosion Control

Hydroseeding plays a critical role in large-scale revegetation and erosion control projects, especially in commercial and industrial settings. The technique is highly effective in stabilising soil on slopes, embankments, and other challenging terrains, making it indispensable for infrastructure projects. By promoting rapid vegetation growth, hydroseeding helps to restore disturbed areas, reduce soil erosion, and improve environmental sustainability. This makes it a preferred method for contractors working on highways, pipelines, mining sites, and other large-scale developments.

Applications in Large Infrastructure Projects

For commercial contractors, hydroseeding offers a reliable solution for managing erosion and promoting revegetation across extensive project sites. Whether it’s reclaiming land after construction or preventing erosion on steep slopes, hydroseeding ensures that the soil is protected and vegetation is established quickly and effectively. This method is particularly advantageous in areas where traditional seeding techniques would be too labor-intensive or slow, providing a cost-effective and efficient way to meet environmental regulations and project timelines.

Historical Background

Origins and Evolution

The history of hydroseeding dates back to the 1950s when Maurice Mandell, a Connecticut-based landscaper, developed the technique. His method, which combined seeds, mulch, and water in a tank and sprayed it onto the soil, revolutionised landscaping and erosion control.

The Hydroseeding Process

Step-by-Step Breakdown

Hydroseeding begins with the preparation of a slurry mixture of seeds, mulch, fertiliser, and water. This mixture is loaded into a hydroseeder, which keeps it agitated and evenly mixed. The slurry is then sprayed onto the prepared soil using a hose or cannon, ensuring even distribution and good seed-to-soil contact.

Equipment and Technology Used

Hydroseeding requires specialised equipment known as hydroseeders or hydromulchers, which vary in size and capacity. These machines are designed to mix the slurry uniformly and spray it over the target area efficiently. Some advanced hydroseeders can cover large areas with high precision.

So why does hydroseeding work so well?

At the start of the process, the seed is suspended in a nutrient rich slurry which is mixed evenly. The contact of the seed with the water in machine triggers the germination cycle. The mulch layer then retains the moisture and holds the soil in place once sprayed. Once sprayed, the seed is at an ideal depth for producing good results and the conditions are right to produce a lush green lawn in very short time.

Composition of the Hydroseeding Mixture

Seed Selection and Varieties

The types of seeds used in hydroseeding can vary based on the project’s requirements. Common choices include grass seeds, wildflowers, and native plants tailored to the local climate and soil conditions.

What is the Role of Mulch?

Mulch is a critical component of the hydroseeding mixture. It helps retain moisture, protects the seeds from erosion, and promotes healthy germination. Common types of mulch used include wood fibre mulch, blended mulch, and paper mulch.

Fertilisers and Soil Enhancers

Fertilisers and soil enhancers are added to the mixture to provide essential nutrients that support seed growth. These additives can improve soil quality and boost the health of the vegetation.

Binders and Tackifiers

Binders and tackifiers act as adhesives in the hydroseeding mixture, helping the seeds adhere to the soil. This prevents erosion and ensures that the seeds stay in place until they germinate.

Hydroseeding is a one step application

The VORTEC hydroseeder system allows a single operator to hydroseed efficiently. The mulch, seed, fertiliser and dye are mixed and applied in a one-step application. Hillsides, banks and other irregular areas that can be a problem with other seeding methods are also very easy to complete with a VORTEC Hydroseeder. VORTEC Hydroseeders are the ideal system for landscape contractors and anyone wishing to provide cost effective, low-labor erosion control and seeding services. The cost to hydroseed is significantly less than the cost of turf and a lawn can be hydroseeded in a fraction of the time it takes to dry seed, meaning labor costs are reduced without increasing the cost of materials.

The cost to hydroseed is a fraction of the cost to turf.

• A hydroseeded lawn requires less water than a turfed lawn.
• Hydroseeding requires much less labour.
• Turf needs to be installed properly. Poorly installed turf can fail.
• Turf is difficult to install on sloping or irregular areas.

Hydroseeding vs. Traditional Seeding Techniques

Traditional seeding methods often involve multiple steps and longer germination periods. Hydroseeding combines all necessary components in a single application, ensuring faster and more uniform growth.

Hydroseeding VS. Dry Seeding

• Hydroseeding is a one step process that reduces labor costs.
• Straw has weed seed in it and hydroseed does not.
• Straw can blow off or clump and needs to be raked off once the lawn is established
• Hydroseeding is considered a premium way to seed but costs less than dry seeding.

What are the advantages Of Hydroseeding?

Fast one step lawn seeding

Hydroseeding is an efficient process that significantly reduces labour and time while ensuring optimal conditions for seed germination and growth.

Rapid Germination and Growth

Hydroseeding promotes faster seed germination and growth due to the optimal conditions provided by the slurry mixture. Vegetation often begins to appear within a week of application and there are fewer weeds.

Great ability to trim around landscape features and walks

Hydroseeding can be applied precisely around various landscape elements such as flower beds, trees, pathways, and other structures. This precision allows for the seeds to be distributed evenly and neatly, ensuring that the vegetation grows uniformly around these features without the need for extensive manual trimming or adjustments post-application.

The easiest way to seed hillsides, steep slopes and irregular areas

Hydroseeding is particularly effective for areas that are difficult to reach or challenging to plant using traditional methods.

Hydroseeding is a premium service that homeowner will pay more for yet it costs you less to hydroseed a lawn.

While hydroseeding is perceived as a high-quality and desirable lawn installation method, making it attractive to homeowners who are willing to invest more for its benefits, it is actually more cost-effective for the provider compared to traditional seeding or sod installation

Even seed disbursement resulting in more uniform germination.

By evenly distributing seeds within the hydroseeding mixture, each seed receives the same exposure to water, nutrients, and soil contact, which promotes consistent germination rates. 

The seeds placement in the nutrient rich solution jump starts the germination process.

The moisture and nutrients in the solution create an ideal environment for seed activation, speeding up the germination process compared to traditional seeding methods. As a result, the seeds can establish roots more quickly, leading to faster and more robust growth.

Better Appearance
