If you are wondering why a local construction company seems to be painting the local hills green, then look no further!
While the green dye may look like paint, the construction company is actually performing an environmentally-friendly procedure known as hydroseeding.
Hydroseeding is a construction industry practice of replanting areas of land which have been disturbed by construction projects and vehicles. A truck mounted sprayer is used to spread a special hydroseeding slurry mixture on the bare ground. The mixture will soon grow into native grasses that help to protect the ground and return it to a natural look.
You might be surprised to learn that in areas that have been affected by wildfires, hydroseeding can be accomplished using an airplane. Aircraft are also sometimes used for construction areas without easy ground access.
Hydroseeding Slurry Mixture
Hydroseeding is accomplished using a slurry mixture of the following items:
- natural grass seeds
- fiber mulch
These items are all added into a tub of water that has been dyed with a natural, green dye. Mixing with water turns the mixture into a liquid form that can be more easily dispersed on landscape.
The only function of the green dye is to show the construction worker where the slurry mixture has been applied. As soon as the first rain arrives after the application of the hydroseeding material, the green dye will be absorbed into the earth and will no longer be visible.
There are many advantages to having land hydroseeded. Hydroseeding is often used for soil retention and to increase soil stability.
As native grasses grow on the hills, their roots will combine together in order to provide structure within the soil. Additionally, the grasses will help to absorb excess moisture from rains and snow. These two things combine to reduce the chance of a landslide or excessive runoff of water.
Hydroseeding is also much less expensive than installing sod, because the planting process requires a lot less physical labor. Additionally, hydroseeding is a lot faster way to plant grass, even in very large areas.
Next time someone mentions the "odd" green painted hills in your area, now you can explain to them that the hills have been hydroseeded and the reasons why. If you have land that you are interested in having hydroseeded, then you should contact a landscaping contractor, such as Bark Blowers & Hydroseeding Inc.
