HydroSeeding Info


HydroSeeding which is sometimes also called hydraulic mulch seeding, hydro-mulching, or hydraseeding) is a planting process in which a slurry containing seed, hydro seeding mulch, fertilizer and a tackifier (bonding agent) is sprayed onto the ground. The slurry is transported in a truck or trailer mounted tank to the job site and sprayed over prepared ground in a uniform layer. In remote areas hydro seeding is sometimes also done using helicopter. Hydro seeding offers many advantages to the traditional process of broadcasting or sowing dry seed. It promotes quick germination and inhibits soil erosion. It is also a very cost effective alternative to sod and offers a significant cost savings as well as many other benefits.


Virtually any grass or erosion control seed that can be planted by seed can be hydro seeded. This includes any sun or shade lawn seed, athletic field mixes, pasture mixes, native grasses, wildflowers, roadside mixes and erosion control mixes. The nutrient rich slurry helps promote fast germination. The hydro seeding mulch helps keep the soil moist to enable the seed to germinate quickly and unlike straw or hay contains no weed seed. The tackifer in the mix acts like a glue to hold the mulch in place and to help prevent washout in the case of heavy rains.


  • Quicker Germination
  • Better moisture retention
  • Better seed to soil contact
  • Hydro seeding mulch contains no weed seed unlike straw or hay
  • Better results at a similar cost
  • Areas such as hillsides and narrow areas that are difficult or impossible to dry seed can be done easily
  • No straw or netting to remove
  • One step and very uniform application
  • Holds soil in place better than dry seeding


Sod provides instant gratification but there are advantages to hydro seeding over sod. As someone once commented, hydro seeding is a lot like sod but you eliminate the middle man.
The advantages of hydro seeding over sod are:

  • You can have a sod quality lawn in a few weeks for less than 1/3 the cost of sod
  • Both hydro seeding and sod require watering but the watering requirements for hydro seeding are less
  • Hydro seeding grows the lawn on your soil and is not a different soil that is transplanted
  • The problem of sod not “taking” is eliminated
  • With sod the roots are cut very short and the sod goes through some shock during shipment and installation


With some of the newer hydro seeding materials that have come on the market it is now possible to save time and money by seeding difficult areas that formerly required labor intensive erosion control blankets.

Products such as BFM (Bonded Fiber Matrix) and FGM (Flexible Growth Media) will provide superior erosion control and fast turf establishment with up to 8 times less labor than erosion control blankets. Unlike blankets these erosion control products bond directly to the soil surface and both hold better and require less surface preparation. On less demanding applications standard hydro seeding materials do an excellent job.


Hydro seeding has grown rapidly in popularity. It offers a number of advantages as a method of planting a lawn, seeding erosion control projects or any seeding application. There are advantages to hydro seeding over other methods of seeding. Everything is done with one machine.

You can seed areas that are difficult to seed with other methods such as steep banks, and narrow areas between walks and mulch beds or between a sidewalk and a curb. You can quickly and easily give your customers the best new lawn at affordable prices. The IAHP can help you find new business and grow the installation part of your business.
