Mixing hydrograss (often called hydromulch) involves carefully combining water, mulch, seed, and fertilizer in a hydroseeder tank to create a slurry that can be sprayed onto the ground for erosion control and grass establishment. Here's a step-by-step guide:
-
Fill the Tank: Begin by filling your hydroseeder tank approximately ¾ full with clean water.
-
Start the Engine and Agitation: Start the hydroseeder engine and engage the agitation system. Run the engine at maximum RPM to ensure proper mixing. Proper agitation is crucial for a consistent slurry.
-
Add Mulch (First Half): Gradually introduce about half of the total mulch you intend to use. Allowing the mulch to hydrate before adding the rest prevents clumping.
-
Incorporate Seed: Add your grass seed at the recommended rate. A common rate is 5-7 lbs per 1000 sq ft, but always check the seed manufacturer's recommendations for the specific seed you are using. This ensures proper seed distribution within the slurry.
-
Add Fertilizer (Optional): If you're using a fertilizer product like "1-2 PUNCH" (or any other water-soluble fertilizer), add it according to the manufacturer's instructions. For the example provided, use 1 scoop per 100 gallons of water. This provides essential nutrients to the germinating seeds.
-
Add Mulch (Second Half): Slowly add the remaining mulch to the tank.
-
Continue Mixing: Continue mixing the slurry until all the components are fully absorbed and a homogenous mixture is achieved. This ensures uniform application and optimal results. The amount of time this takes can vary.
Important Considerations:
- Water Quality: Use clean water free from debris or contaminants. Poor water quality can affect seed germination and slurry consistency.
- Mulch Type: Different mulch types (e.g., wood fiber, paper, blended) have different mixing requirements. Adjust mixing time and water ratios accordingly.
- Equipment: The specific instructions for your hydroseeder may vary. Consult your equipment manual for detailed guidance.
- Viscosity: The ideal slurry viscosity depends on the application and the type of hydroseeder you're using. Adjust water and mulch quantities to achieve the desired consistency.
- Application: Apply the hydrograss slurry evenly to the prepared soil surface. Overlapping passes will promote uniform coverage and consistent growth.
By following these steps, you can create a well-mixed hydrograss slurry that will effectively establish vegetation and control erosion.
