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.
