HYDROSEEDING

LAKE SUNAPEE LANDSCAPING &PROPERTY MANAGEMENT

Hydroseeding is a way to plant a lawn. A hydroseeder is a combination of a large tank, a pump, hose, and nozzle. This configuration can be used for spraying large volumes at low pressures. Water is the vehicle or mover of the materials that really do the work, just as it is in latex paint. The water dissipates, evaporates, and transpires leaving the mulch, seed, and other constituents such as lime, fertilizer, and tackifier to do their work. The main use of this device is to apply seed for lawns, but it can be used with any seed such as wildflower. The name hydroseeder says it all. The water is the largest part of the equation by volume, and it creates a perfect environment for seeding, and for dissolving nutrients that are made directly available to the seed after being mixed together. The seed and mulch is also very evenly suspended in the slurry that is created in the tank as it circulates. Seeding lawns by hydroseeder makes them come up fast, and if the ground is well prepared a very good root system can be established quickly.

Hydro-mulching can be done with the same machine. This procedure involves using the machine to spray out mulch without seed, but with other agents that will help retain slopes. Special polymers called tackifiers can be added to the mixture in the tank. These help paste or bind the mulching materials together. This is a method that can help reduce erosion caused by water running on slopes that have already been seeded or that have some growth already started on them.

The number one cause of soil loss in the US is from construction site erosion, and the speed and effectiveness of hydroseeding helps to minimize this problem. It is faster to apply the seed, lime, fertilizer by spraying it with the seed and mulch in one step rather than all the leg work it takes to apply each constituent individually. Hydroseeding may stimulate a lawn to come up as much as twice as fast as lawns planted by traditional methods.

There are also ways to speed up the germination process. One is to freeze the seed cracking the protective shell around it, which leads to quick germination. This can be done prior to normal lawn seeding as well. Another approach is to pre-soak the seed so it sprouts prior to being put into the spray mixture. These two methods can be combined when hydroseeding. That can really get things growing fast.

Our favorite mulch is made mostly of recycled paper and wood fiber. Organic amendments can be used instead of petroleum based products. The way things mix together in the tank, you use much less fertilizer, lime, etcetera, then when using traditional seeding methods, and it is much more effective. In sensitive areas you can leave out fertilizer or lime so that their deleterious effects will not be felt. This may be the best way to start a new lawn.
