HydroMulching is generally the same as Hydroseeding but the quantity and types of mulches are different.

Hydroseeding involves mixing a slurry of seed, a growing medium (mulch) and fertilizer together with a variety of other products such as Tackifier and wetting agents.

Hydromulching uses much greater quanties typically a hydroseeding slurry would apply the mulch at a rate of 1000kg/ha where as Hydromulching starts at a rate of 2000kg/ha there is no upper limit.The advantage of Hydromulching is that there is much more ability to retain moisture. The increased thickness of the mulch means that this layer acts as a nursery and growing medium for the seed.

Hydromulching can be used on areas where the fertility is poor it can help avoid the situation that once the young plantlets consume the minerals in the fertilizer there is nothing left for them to survive on so they die.

Hydromulching Materials

• Wood and Paper: These materials are the same as hydroseeding and come as either a 100% wood fibre, a 70/30 wood/ paper blend, or a 50/50 wood/paper blend. There is no 100% paper for hydromulching because paper only when applied in a heavy application results in a very hard crust that small plants cant penetrate. The blends have different properties but in our experience the 100% wood gives the best results.

• Wood and Peat: Where the site has low fertility conventional wood based hydroseeding mulches can be combined with Peat to add additional bulk to the hydroseeding mix. Peat adds additional humus as well as further increasing the moisture retention abilities of conventional wood based products. GoRoots are the only UK company that can offer a peat based mulch option.

• Straw: Hydromulching allows for the incorporation of different materials in particular straw available chopped and blended with paper in bales similar to conventional hydroseeding mulch or as raw bales. Raw straw bales are applied using a special shredder blower
  

Hydromulch Applications.

Hydromulch is suitable for all sites where hydraulic seeding is considered in particular where there is poor top soil coverage.

Hydromulch and Soil Erosion.

Hydromulching is best used with erosion control matting when the matting is placed over the hydromulch because the thick layers of mulch tend to prevent the seedlings attaching them selves to the bed rock.

Hydromulch and GoRoots.

We at GoRoots belive in hydromulching and ask anybody considering and sort of hydraulic seed application to consider the benefits of a thicker and deeper mulch bed. In Hydroseeding the mulch is applied so thinly that it often only serves as a guide to show where the contractor has been and has little benefit. We apply all ot our hydroseeding and hydromulching at the maximum rate we are able to do this because we have access to a EU manufactured product than can be procured at a fraction of the cost of traditional US manufactured products. The thicker the slurry the better the out come.
