Why Hydroseeding is Preferable to Dry Seed or Sod

Do you have a large plot of land you are considering planting grass on? Are you looking to prevent sun damage, soil displacement, or eliminate soil erosion? If one or all of these apply, you may be researching the advantages and disadvantages of dry seed, sod, and hydroseeding.


Hydroseeding is a process for planting grass. This process is especially effective for large plots, hillsides, slopes, or other areas where planting is difficult. Hydroseeding is even used on construction sites as an erosion control technique, or anywhere from golf courses to mountainsides. The process involves using a slurry of seed, mulch, water, fertilizer, a variety of organic bonding agents, and green dye, to be able to see what has been sprayed. The slurry is then applied to the surface with pressure to allow for seed germination and turf development.


Rather than scattering grass seed or laying down sod, all hydroseeding involves is simply spraying the slurry over the planting area. For a large area, hydroseeding can be completed very quickly and grass growth can be seen in a week with mowing maintenance beginning in as few as 3 weeks. These are some other benefits of hydroseeding over dry seed and sod:

Hydroseeding Versus Dry Seed

  • Hydroseeding is a faster, one-step process
  • Hydroseeding eliminates the use of straw and does not produce dust during application
  • Hydroseeding takes one-third the amount of time it takes to dry seed, saving money on labor costs
  • Dry-seeded soil needs to be raked once the lawn is established
  • Hydroseeding costs less than dry seeding even though it is considered a premium service
  • Hydroseeded soil sees faster germination and fewer weeds than dry seeded soil
  • The look of a newly hydroseeded, lush green lawn is much preferable to the appearance of a dry seeded lawn
  • Dry seed is susceptible to displacement by birds and wind
  • Hydroseeding Versus Sod


    • Hydroseeding costs 60% to 80% less than laying sod
    • A lawn that has been hydroseeded requires less water than one that has been sodded
    • Sodding does not have a 100% success rate, since the harvested sod’s roots can be cut too short and will not grow when planted
    • Sodding requires much more labor than hydroseeding

      Dewatering With Floc Logs


      Before hydroseeding, you may need to consider dewatering, a crucial component of developing the land. Dewatering soil will remove any excess water, rendering it firmer and more optimal for planting, construction, and a variety of other projects.


      Hydrograss Technologies, Inc. is especially equipped for dewatering projects because of our award-winning products, including floc logs, which are semi-hydrated gel polyacrylamide blocks that remove fine particles and reduce NTU values. Floc logs are a new and reliable method of removing contaminants from water.

      Successfully growing grass over a large area, which was once a daunting task, has never been easier due to the advent of hydroseeding technology. If you are looking for hydroseeding or dewatering services, contact Hydrograss Technologies today.
