Hydroseeding is fast becoming a popular method for seeding new lawns. Hydroseeded lawns have a mixture of seed, water, fiber mulch and fertilizer blended together and sprayed over a prepared seedbed. This protective cocoon around the seed helps give it the correct conditions needed for germination. Caring for a hydroseeded lawn is imperative to ensure successful germination and grass establishment. Hydroseeded lawns use the same care practices that regular seeded lawns use.
Set up sprinklers and water your hydroseeded lawn two to three times per day. Water until the mulch is wet throughout its entire thickness. Continue this for two weeks.
Back off on the watering after two weeks so that you are watering once a day. Water until the mulch is moist. Continue watering once per day until your first mowing.
Mow your grass to a height of 2 inches after it reaches 3 inches in height. Discontinue watering once per day and move to your normal irrigation schedule.
Raise the cutting height up to 3 inches gradually after the first mowing. Longer grass has more surface area to efficiently conduct photosynthesis.
Fertilize your hydroseeded lawn one month after planting using a lawn fertilizer that is high in nitrogen. Use a broadcast spreader that is set at the fertilizer bag's indicated rate to fertilize your hydroseeded lawn.
