If planting a relatively large area, hydroseeding can be completed in a very short period of time. It can be very effective for hillsides and sloping lawns to help with erosion control and quick planting. Hydroseeding cost less than planting with sod and utilizes the native soils already in place. Results are often quick with high germination rates producing grass growth in about a week(seaonally dependent) and mowing maintenance beginning around 3–4 weeks from the date of application. Fiber mulch accelerates the growing process by maintaining moisture around the seeds thereby increasing the rate of germination.
