This is the #1 thing you can do to improve your turf...PRIOR TO SEEDING.
Soil compaction is the number 2 or 3 problem with turfs (seeded and sodded) [shade is #1, and inadequate water is #2]. Soil Preparation is a way to ensure a good seed bed, improve water infiltration, and enable good root establishment. We only offer soil preparation as an option associated with our hydroseeding services. We will bring in equipment and till the soil to a flat seed bed ready to grow your new hydroseeded lawn and minimize surface imperfections in the final turf. Depending on the job, equipment will vary from large (skid steer) to small walk behind equipment. On large jobs, we may bring in multiple, skid steers with soil "preparator" and soil "levelers" to get the site ready for hydroseeding.
Prep your soil prior to seeding! This is your best chance at getting your turf off to a good, and long term, start while reducing years of future problems with irrigation, fertilization, and pest control. Goose Grass loves compacted soil, as does Crab Grass... but all the turfs home owners want can't stand Compacted Soil!
