Lawn Renovations

The best things in life come with a little bit of sweat and hard work. And your lawn is no exception.  That's why Dowco has designed a fall lawn renovation program that includes everything you need to have the best yard on the block.

Our St. Louis Lawn Renovation Includes: 

1. Double Aeration
2. Overseeding
3. Seed Starter Mulch 
4. Seed Germination Fertilizer 
5. Composting (Optional) 


St. Louis soils are mostly composed of hard clay.  Core aeration for your lawn gently removes plugs of soil, allowing the ground to breathe better and absorb the water and nutrients that we feed it. Our aeration equipment removes 1.5 – 3 inch plugs of soil and leaves them on top of the lawn.  A double aeration includes two passes in opposite directions to multiply the opportunity for a successful lawn.

Fall is the best time of year to core aerate your lawn. Introducing new grass seed at the same time will fill in thin areas and thicken existing turf providing the best defense against common lawn problems. Power raking and slice seeding are not appropriate for mature lawns. These destructive practices tear the roots of the established grass plants causing extensive damage and forces a restart of your lawn instead of a gentle fall rejuvenation.

The primary benefits of core aeration include: 

  • Reduce soil compactionJust as you wouldn’t try to plant a flower in concrete… a rock hard, compacted soil bed is not conducive to a great lawn either! Whether or not you are over-seeding this year, loose soil allows grass roots to plunge deeper into the soil to find vital water resources in times of stress.
  • Reduce thatch build upThatch is made up of grass stems and roots that accumulate faster than they breakdown. Excessive thatch creates an environment that is favorable to pests and disease.
  • Promote root growthBy penetrating the soil, you’re allowing moisture, air, food (fertilizer) down to the root zone where nutrients are absorbed.
  • Enhance seed germinationGrass seeds germinate easily in aerator holes as the holes provide them a place to hide. Grass seed must be in direct contact with topsoil to germinate and will not germinate in thatch.

Different factors contribute to the break down of the grass including foot traffic, heat, lack of water, environmental conditions, pet waste, etc. Introducing new grass seed will fill in bare or thin areas as well as thickening existing turf. The best defense against weeds, drought and disease is a thick, lush turf. 

The best time to over-seed is in the fall. Mother Nature provides us with more precipitation and cooler weather, diseases are less active, and the soil is still warm. Spring is the time to apply pre-emergents and your desirable grass seeds typically lose the battle against pre-emergents. Aerating is an important factor prior to over-seeding and the aeration will break the barrier provided by the crabgrass pre-emergent. Additionally, the seedlings often do not have enough time to reach maturity before the heat of the summer hits. 

Many lawns in the St. Louis area were originally installed with Bluegrass sod. Introducing a Fescue blend will help to resist insects and disease. Fescue is proven to provide superior drought resistance, works well in sun and shade, and exhibits early spring green up.

Dowco will overseed with a high-quality tall Fescue blend seed which is drought tolerant, works excellent in sun & shade, and exhibits early spring green up. Dowco technicians will apply seed more generously in bare and trouble spots, typically located along the driveway or in high traffic areas. After aerating, Dowco will seed your entire grounds with at least 5 pounds of seed per thousand square feet which is a heavy rate.

The primary benefits of lawn overseeding include: 

  • Fill in bare or thin spots
  • Improve turf density
  • Enhance lawn color
  • Better resistance to weeds
  • Improve insect resistance
  • Increase resistance to drought

Seed Starter Mulch

Water control is extremely important in seed establishment. The starter mulch is a great tool for property owners to use as a gauge of their watering.  When Dowco first puts down the starter mulch it will be a grey color like the photo shown above. It will start to fade out to a near white color as it begins the decomposition process and reaches the end of its useful life.

Unlike straw, starter mulch contains no weed seeds and will not blow away in wind. It is also biodegradable and requires no cleanup.

Seed Germination Fertilizer 


This application will jump start the growth of the new seedlings so they can germinate before winter. The fertilizer is specially formulated for new seedlings and accelerates root growth. 

It improves the lawn’s ability to soak up water and nutrients during the growth period. A great foundation is essential to a long life of your turf.

If you’re on Dowco’s fertilization and weed control program, you have nothing to worry about. We’ll take care of the scheduling and appropriate treatments for you. No weed control products will be used if new grass seed was applied. 

Lawn Composting

Dowco_Lawn_Composting.jpgDowco’s newest lawn composting service was designed for eco-friendly property owners who want the greenest lawn! It is a process that incorporates a thin layer of rich, earthy, organic material to your existing lawn. This material, called compost, is the end product of a complex feeding pattern involving hundreds of different organisms, including bacteria, fungi, worms, and insects. What remains after these organisms break down organic materials is the rich, earthy substance that gardeners value so highly as a soil improvement.

There are many reasons why you should add compost to your lawn and here are just a few:

  • Enhances Grass Growth Naturally

The nutrients in compost, such as nitrogen, are at much higher levels than regular fertilizer. Compost has lower salt content than fertilizer and doesn’t burn the lawn like fertilizer can.

  • Conserves Water 

Compost helps plants grow longer roots which assist in conserving water. You could use 30% less water to water the lawn because the compost helps hold moisture in.

  • Prevents Weeds

Stronger, healthier grass plants grow densely, reducing the space for opportunistic weeds to grow.

  • Prevents Disease

The composting process enhances the reproduction of beneficial bacteria, which causes high temperatures and reduces oxygen, thereby killing viruses such as E coli, salmonella, and other harmful bacteria. It kills disease and the pathogen by “cooking” the material over a long period of time (1-2 years).

  • Amends Soil

Compost amends clay soil (prevalent in St. Louis) by introducing organic matter that clings to the clay particles and splitting them up. It then introduces micro-organisms that eat the organic matter and create byproducts which further loosens the clay and helps it breathe. When your soil is able to breathe, the grass roots can make better use of the water and nutrients we’re feeding the lawn.

It all sounds great, right! But, composting is not for you if you’re not interested in the bigger picture – When we leave you’ll have a bit of a mess of compost laying on your lawn and you’ll have to tolerate it looking like “crap” for about a week or so. If you have a party or you’re taking pictures of your lawn to sell the house, you won’t want this service. Watering it in will help with the appearance. Also, if you can’t afford it – it’s not a cheap option, but we know that cheap doesn’t always equal best. The results we’ve seen by introducing compost keeps lawns GREEN and lush!
