    Anybody have any experience hydroseeding with Sideoats, Big Bluestem, Switchgrass, Little Bluestem, and Indian Grass?

    We have got this job as a sub on a new high school project. 60,000 square feet to be seeded with the above seed. In the past, when hydroseeding wild flowers, we broadcast seed then mulch over.

    Would the same process work here or should we mix the seed in the slurry?

    Thanks in advance!!!

    Your best bet is to broadcast seed and cover with hydromulch, even better would be to drill seed and cover. If you must hydroseed it then double you seed amount per acre.

    Paul, what is the reasoning for doubling the seed poundage per acre if your hydroseed? In this case I would be more concerned that the various seed would not stay evenly supended in the hydromulch and you would get spotty patches. Is doubling the seed rate when hydroseeding standard, or specific to this instance? Just curious.

    Thanks,
    Kevin

    With wild grasses and flowers the seed must come in contact with the ground. Doubling the seed insures that more of the seed will contact the ground. Most seed suppliers have seed rates for different types of installation, drill seeding using the least amount of seed, followed by broadcast seeding and ending with hydroseeding.

    Thanks for the information.

    How do you guys hydroseed? When hydroseeding rates can be cut! You should spray your mulch downward at no more than a 45 degree angle so that you are shooting it into the dirt. This will achieve better soil contact than braodcasting.

    The problem with natives here is cost IDOT class 5A runs $1600 per acre (thats only five 5 lbs of live seed) for the seed only. if you have anything left in your tank your not getting it all down, plus the fluffy seed is hard to mix in your tank seems to clump together with the mulch. The Truax seeder works the best for this with it's special fluff seed box. Then Hydro mulching over it seems the really help get it rolling.

    What type of mulch are you using? We do not have this problem here. Hey you learn something new everyday. :D That has been the biggest adjustment for anyone in HTPA is learning that what works in part of the country will not in another. It is still good to here what everyone is doing, you never know what you will be able to use on the job.

    Sean, We use Mat-Fiber 100% wood mulch or Conwed 100% wood mulch.

    Also have you used much BFM, instead of erosion control mat (like straw mat)?
    I've been playing with the idea of using it in some areas that really don't need erosion control but have it on the plans.
    I've got some samples of Soil Guard that I'd like to see if it works as well as straw netting.
