What Is Hydroseeding?
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 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.
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 the 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 a very short time.
