Quick Tips

  • Dethatch and Aerate
  • Overseed & Fill Bare Patches
  • Fertilize with Milorganite - Southern (Easter) and Southern & Northern (Memorial Day)

Early Spring Lawn Prep

• Avoid heavy yard work in the spring until the soil dries out – foot traffic and hard raking can compact or disturb soggy soil and damage tender, new grass shoots.
• In areas with heavy snowfall, leftover snow piles can smother the grass underneath and foster mold growth. As the weather warms, spread snow piles out with a shovel to encourage melting.
• Once the soil is dry, give your lawn a good spring cleaning to encourage grass growth and discourage pests and diseases. Remove leaves and fallen debris, and gently rake to separate the grass shoots.  


Thatch acts as a barrier to water, nutrients and air reaching the soil and should be removed to ensure a healthy lawn. Dethatch cool-season grass in the spring and warm-season grass in early summer.  Use a metal rake in the spring to pull the thatch out of the lawn and prevent damaging new growth. 


Aeration is the removal of a small core of soil or the punching of a thin hole into the soil.  Aeration provides a many benefits that lead to a healthier lawn such as improving drainage, reduces weeds, alleviates soil compaction and helps prevent thatch.  Spring or fall is the best time to aerate cool-season grass and warm-season grass between mid-spring and summer.  

Topdress with Compost

Topdressing your lawn with compost builds a deeper root system, increases water holding capacity, and nutrient retention. Apply 1/4 to 1/2" good quality compost to the lawn. View topdressing with compost video for more information.

Overseed & Fill Bare Patches 

Spring or fall is the ideal time to overseed your lawn; mix Milorganite with your seed 4:1 ratio.  Avoid leaving large patches of bare soil; overseed bare patches to reduce weeds. After you rake out the existing dead grass, top dress with ½”compost, mix and apply seed and Milorganite, gently rake in and water.


Fertilize with an application of Milorganite in April (warm season grasses) and Memorial Day Weekend (both warm & cool season grasses). If you applied a granular pre-emergent that contained fertilizer, follow up with a Milorganite application two weeks later.


If necessary apply a pre-emergent herbicide for crabgrass control.  It is best to wait for the soil to warm before applying pre-emergent, crabgrass germinates best at 59F to 65 F.


Proper mowing can strengthen your lawn’s resilience against pests and weeds. The best way to mow is often.  For a thriving lawn, never cut away more than 1/3 of the grass blade in any one mowing.


Remove weeds by hand, be sure to get the entire plant and root if possible.  If weeds have taken over, spot spray with a post emergent herbicide. Gardening expert, Melinda Myers, shares eco-friendly weed control tips.
