Aeration, Overseeding & Topdressing

The Secret to Beautiful Turf

Aeration, overseeding, and topdressing in the second half of the lawn care season are key to improving the growing environment for your lawn. At Velvet Green, we always complete these three services in order described. Technically, this means we are “under-seeding” your lawn as we add the compost on top, but that means the seed is exactly where it needs to be to grow– in the soil, not on the soil.

Benefits to Core Aeration, Overseeding, and Compost Topdressing:

  • Fills in bare spots to provide a thick, green lawn
  • Chokes out weeds and crabgrass
  • Loosens and decompacts your soil
  • Increases root development
  • Increases water retention
  • Improves overall plant health

There is no arguing the fact that a thick healthy lawn is the absolute best defense against weeds and crabgrass.  If you have thin or bare areas in your lawn, aeration, overseeding, and compost topdressing is an absolute must.


For many years, professional golf course greens keepers have known that the secret to a beautiful, dense turf is to aerate their course two or three times each year to allow the healthy grass roots to thrive. Aeration removes cores of soil from the lawn to allow for improved exchange of gasses between the soil and the atmosphere, improved water filtration, improved rooting, decreased soil density, and a site for seed germination. Aeration is performed during the fall months of the year after the heat and humidity of summer have broken.


When overseeding, we use our Velvet Green Resilient Turf Mix. This proprietary grass seed mixture contains grass varieties that are lateral spreading and salt-, heat-, and drought-tolerant. This combination of grass seed will help lawns remain resilient through some of the harshest summer conditions in the future. Introducing new, improved cultivars of turfgrasses helps keep the lawn thick and healthy.


Adding a thin layer of compost over the seed bed after aeration and seeding have been performed is like buying insurance on the work.  It gives a light covering to the seed which protects it from wind and birds.  It also insulates the seed and allows it to stay more moist from irrigation. Topdressing reduces lawn stresses, helps keep thatch under control and acts as a long term natural fertilizer.
