Lawn Care - Spring Maintenance

Quick Tips:

1. Fertilize (warm grass) in early April
2. Fertilize (warm & cool grass) in late May
3. Dethatch and Aerate

Start your spring lawn care by with removing any debris from winter.  Follow these simple steps for a greener, healthier lawn!


Thatch is a layer of living and dead stems, roots and crowns that develop between the green vegetation and the soil surface. Thatch acts as a barrier to water, nutrients and air reaching the soil and should be removed to ensure a healthy lawn. The best time to dethatch a cool-season grass is early spring or early fall and warm-season grass in early summer. For small areas, use a metal rake to pull the thatch out of the lawn. For large lawns, rent a power dethatcher from your local garden center.


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.  Fall or spring is the best times to aerate cool-season grass and warm-season grass between mid-spring and summer.  


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.

Bare Spots  

To reseed bare patches in the lawn, rake out the existing dead grass, add some top soil along with a handful of seed and Milorganite and gently rake in and water.


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 one-third of the grass blade in any one mowing. 


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


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.
