Hydraulic seeding (Hydroseeding) in Gatineau and Outaouais
Hydraulic seeding (hydroseeding) is a professional technique that allows rapid lawn establishment by projecting a mixture of water, seeds, mulch and fertilizer onto prepared soil.
This technique is particularly used for new land, new constructions, embankments and large areas.
We offer hydraulic seeding (hydroseeding) services in Gatineau, Hull, Aylmer, Cantley, Chelsea, Val-des-Monts, L'Ange-Gardien and Ottawa in the Outaouais.
Hydraulic seeding: the real professional version of « spray-on lawn »
Hydro-seeding, hydroseeding, hydromulching, hydro-foam, spray lawn… It goes by many names. Hydraulic seeding is the professional term for this proven technique.
Forget miracle spray-can solutions. Hydraulic seeding is a high-precision mechanical application: a custom mix of seeds, fibres, water and nutrients, sprayed uniformly on rigorously prepared soil.
At Hortiplan Outaouais, we combine soil science, field expertise and mixes adapted to the local environment to create a dense, durable and high-performing lawn — whatever you call it.

The first shoots generally appear between 7 and 10 days when conditions are favorable and watering is adequate. A dense lawn develops progressively in the following weeks.
A solution adapted to all types of terrains
Slopes & embankments
Stabilizes the soil, prevents erosion, allows for uniform establishment.
Poor or degraded soils
Revitalizes the soil and promotes deep rooting.

Why choose hydraulic seeding?
Hydraulic seeding allows for rapid, uniform, and highly performant establishment, especially when starting from scratch on a prepared soil base.
Unlike sod, which offers an immediate result with already cultivated and selected lawns under certain conditions:
hydraulic seeding allows for an entirely personalized formulation, precisely adjusted according to:
- •the type of soil
- •sun exposure
- •drainage
- •drought resistance
- •terrain usage (residential, municipal, foot traffic, etc.)
Hydroseeding vs Sod - The true comparison
Hydraulic Seeding
- Custom mix
- High biodiversity
- Excellent drought resistance
- Ideal for slopes & large surfaces
- More economical on a large scale
Sod
- Cultivated lawns ready to install
- Immediate result
- Several types at Hortiplan
- Excellent rapid solution
- Less adapted to large slopes
Two excellent methods — not for the same terrain conditions.
Frequently asked questions about hydraulic seeding
Have another question? Feel free to contact us.
How long before the grass grows?
Germination generally starts between 7 and 10 days, depending on temperature, sunlight, and watering. Full coverage establishes in 3 to 5 weeks.
Is it more economical than sod?
Yes, especially for large areas. Hydraulic seeding is often more advantageous at scale, whereas sod is more expensive to purchase and install.
Is it the best solution for slopes and embankments?
Yes. It's the most effective method for stabilizing slopes, preventing erosion, and achieving uniform coverage on inclined surfaces.
What maintenance is necessary after application?
- Regular watering in the first weeks
- First mowing higher than normal
- Light fertilization as needed
✓Everything is clearly explained at the end of the work.
Does hydraulic seeding replace soil structuring?
No. When starting from scratch, good soil preparation and structuring are essential BEFORE hydroseeding to ensure the durability of the lawn.
What is the difference with slit-seeding?
- Slit-seeding: corrects an existing lawn
- Hydroseeding (hydraulic seeding): ideal when starting anew on prepared soil
✓Two excellent methods — for two different contexts.
Is this method compatible with watering restrictions?
Yes. The mixture is designed for better moisture retention, making it more compatible with watering restrictions in Gatineau and Outaouais.
