In this article, we will explore hydroseeding, an increasingly popular planting method in Quebec and elsewhere in the world.

What is hydroseeding?

Hydroseeding is a process that involves spraying a mixture of seeds, fertilizer, mulch, water, and colorants using a pump. This technique allows for quick and uniform application over large areas, making seeding both simple and effective. It helps prevent soil erosion and promotes the growth of grass and other crops, while permanently transforming the land.

The different types of hydroseeding

There are several types of materials used for hydroseeding, depending on the specific needs of the project.

Straw, paper and wood fiber mulch
This is the most common type of hydroseeding because of its excellent seed growth potential while reducing erosion. Mixes can vary depending on the amount of mulch and seed, and may include sticky chemicals as additives. Paper mulch, made from recycled newspapers, is the most economical and easy to spray. In contrast, straw or wood fiber mulches offer better erosion resistance due to their greater weight.

Erosion Control Mulch
This type of mulch is particularly effective in areas prone to high erosion, such as steep slopes and rivers. It uses a water-resistant binding agent to create a dense cover, facilitating seed germination while controlling erosion. This type of hydroseeding is generally more expensive.

Alternatives to topsoil
For land depleted of nutrients due to construction work, hydroseeding offers cost-effective solutions. Indeed, the supply of topsoil over large areas can be very expensive.

Why choose hydroseeding?

Hydroseeding has many advantages:

Save time and money
This method is less expensive than sod because it requires less labor to install. Hydroseeding requires a smaller crew, making it an economical option.

Erosion control
It is the preferred method for stabilizing soil and controlling erosion. Thanks to its sticky texture, hydroseeding resists heavy rain and strong winds, making it a wise choice for risky areas.

Adaptability
Hydroseeding is used by a variety of industries, including construction, agriculture, and even for ecosystem restoration after wildfires. It can serve a variety of purposes, from creating lawns to stabilizing slopes.

How to get quality results?

The results of hydroseeding are generally superior to those of other methods, as it allows for better root penetration into the soil. The mixture of seeds and fertilizer is applied at an optimal pressure, ensuring uniform distribution. In addition, the adhesives present help the seeds to attach and promote their growth.

Moisture retention

One of the key benefits of hydroseeding is its ability to retain moisture, allowing for a reduction in watering requirements. The process can hold up to 10 times its weight in water, which speeds up germination and protects seeds from the elements.

Cost of hydroseeding

The cost of hydroseeding typically ranges from $0.05 to $0.20 per square foot, or $2,000 to $4,000 per acre, depending on various factors such as the size of the area to be seeded, the type of mulch, and the equipment used.

Best time for hydroseeding

The ideal seasons for hydroseeding are spring and fall, due to the mild temperatures and favorable rainfall. This allows the lawn to establish itself before winter and thrive in the spring.

Seed selection

The choice of seeds depends on the climatic conditions, the type of soil and the desired result. Varieties such as fescue, rye, bahia, bermuda and bluegrass are commonly used, as well as wildflowers for an attractive aesthetic appearance.

Implementation of hydroseeding

To carry out hydroseeding, it is essential to test the soil, measure the area, choose the appropriate seeds and prepare the mixture. The use of specialized equipment is recommended to ensure a quality result. Proper maintenance is also crucial to ensure the durability of the land.
