What is Hydroseeding and How Does it Work?

What is Hydroseeding?

Hydroseeding is a seeding technique that involves spraying a specially formulated mixture onto the soil. The mixture comprises seeds, mulch, fertiliser, tackifier, and water. This process allows for even seed distribution and creates an ideal environment for seed germination and plant growth. Additionally, hydroseeding is an eco-friendly option as it minimises soil erosion and utilises organic materials. Hydroseeding excels in establishing lush lawns for residential properties, parks, and sports fields. In commercial settings, hydroseeding proves invaluable for erosion and sediment control on construction sites.

How Does Hydroseeding Work?


Hydroseeding involves spraying a blend of grass seed, mulch, fertiliser, and water onto prepared soil, creating an ideal environment for seed germination. This method promotes robust growth, allowing the grass seedlings to develop into a lush and vibrant lawn. The combined elements in the hydroseed grass mixture work synergistically, fostering a conducive setting for healthy root establishment and ensuring a dense, uniform lawn coverage. The process is efficient, providing a rapid and effective solution for achieving a thriving green landscape.


Components of the Hydroseed Mixture

Hydroseed mix comprises essential components for successful germination and growth.

Grass seed selection, tailored to project specifics like climate and soil type, ensures optimal outcomes, be it ornamental, sports, or erosion control purposes.

Mulch, crafted from wood fibres, paper, or biodegradable materials, acts as a protective shield, retaining moisture and providing a stable environment for seed development.

Fertiliser kickstarts growth, offering crucial nutrients for young plants.

Water, a fundamental element, hydrates seeds, dissolves fertiliser, and forms a slurry when combined with other components, essential for the germination process.

This synergistic blend creates an ideal environment, fostering robust plant development in hydroseeding applications across diverse projects.


Types of Seeds Used

Diverse hydroseed grass varieties, including bluegrass, fescue, rye, Bermuda, Bahia, centipede, and native grasses, exhibit varying tolerances to factors like climate, soil type, and maintenance needs. Each variety contributes distinct characteristics to hydroseeding projects, ensuring adaptability and resilience.

  • Bluegrass: Known for lush, fine texture and cold tolerance.

The Hydroseeding Process


1. Site Assessment and Soil Preparation

Our experts evaluate the site conditions, soil quality, and terrain characteristics to customise the hydroseeding approach.


To prepare for hydroseeding, customers must remove debris, rocks, and existing vegetation to establish a clean canvas for the new lawn. Conducting a soil test is essential to gauge nutrient levels and pH. This meticulous site preparation is crucial, ensuring optimal seed-to-soil contact and promoting uniform growth for a successful hydroseeding outcome.


2. Customised Seed and Mixture Selection

Based on your specific requirements, we carefully select the appropriate seeds, mulch, and additives to ensure optimal hydroseeding results.


3. Application

Our experienced technicians utilise specialised hydroseeding equipment to uniformly apply the mixture, ensuring comprehensive coverage.


The hydroseeding process starts with the slurry, comprising grass seed, mulch, fertiliser, and water, being loaded into the machine's tank. A powerful pump propels the slurry through a lengthy hose, precisely distributing it across the prepared area through a specially designed nozzle. The spraying process coats the soil with a green layer, fostering seed germination and the initial stages of growth, ensuring an even and effective hydroseeded area.


3. Post-Hydroseeding Care

We provide guidance on proper watering techniques and maintenance practices to facilitate successful seed germination and establishment.


Adequate and consistent watering is imperative for the success of a hydroseeded lawn, particularly during the critical germination and establishment phases and when learning how to care for hydroseed.


Mowing: Once the grass reaches a recommended height, typically 3 to 4 inches, mowing can commence. Regular mowing encourages healthy growth, strengthens roots, and promotes a lush appearance.


Fertilising: Applying a balanced fertiliser at appropriate intervals provides essential nutrients, promoting vigorous growth, colour, and overall lawn health.


Weed control: Implementing effective weed control measures is crucial and hydroseeding will help your lawn remain weedless. This is just one of the hydroseeding pros. Regular inspections and targeted herbicide applications can prevent weed competition and maintain the integrity of the hydroseeded area. Following these practices ensures the long-term health and vibrancy of the hydroseeded lawn.


Before and After Hydroseeding

Depending on environmental factors, you can expect visible results within a few weeks, and a healthy, vibrant lawn within a few months.
