Lawn Hydroseeding Ingredients

Seeds

• Hydroseeding seeds, for the most part, are the same ones you use for growing a lawn by traditional methods. The region's climate and the local soil's growing conditions determine which species and variety will thrive. But according to Fairway Greens, a landscape company, St. Augustine and tiff Bermuda grass are two types that shouldn't be used for hydroseeding.

Fertilizer

• Hydroseeding companies decide on which fertilizer to use. One contractor might choose a fertilizer high in phosphorus, while another uses one that has nitrogen, phosphorus and potassium in equal proportions. It's important that the chosen product have a track record as a starter fertilizer that boosts grass seed germination.

Mulch

• Hydroseeding mulch is usually made of wood fiber, but sometimes it is mixed with paper. The mulch protects the seeds and retains moisture to keep them from drying out during the germination period.

Water

• Water carries the mixture through the pressure hose and it irrigates the seeds. The mulch also absorbs some of the water, reducing evaporation. The seeds embedded in the mulch rest in a moist medium, which results in fast germination.

Tackifier

• Tackifier is a gluing agent that binds to the seeds and mulch, holding them in place on the soil surface. This ingredient keeps the wind and rain from carrying away the seeds. Tackifier manufacturers make both synthetic and natural tackifier.
