Soil Testing: Conduct a soil pH and nutrient test using a DIY kit or send a sample to a local lab. Understanding your soil’s composition is fundamental to choosing the right fertilizers and amendments for a thriving lawn within your do it yourself lawn care program.

April: Spring Awakening in Your DIY Lawn Care Program

Spring is now in full force, and your do it yourself lawn care efforts should ramp up to capitalize on the growing season.

First Fertilizer Application: Apply the first fertilizer dose based on your soil test results. Opt for a starter fertilizer with a balanced N-P-K ratio or one specifically recommended for cool-season grasses in spring.
Watering Initiation: Begin regular watering if natural rainfall is insufficient to provide about 1 inch of water per week. Early morning watering is best to minimize evaporation and fungal diseases.

Crabgrass Pre-Emergent Treatment: Apply a pre-emergent herbicide to prevent crabgrass seeds from germinating. For an eco-friendlier do it yourself lawn care program, consider corn gluten meal, a natural pre-emergent.

May: Weed Control and Continued Growth in Your DIY Lawn Care

As temperatures rise consistently, weeds become more active, requiring focused attention in your do it yourself lawn care program.

Regular Mowing: Continue mowing regularly, adjusting the frequency as needed based on grass growth. Maintain the 3-inch mowing height for most cool-season grasses to promote healthy root development and shade out weeds.
Second Fertilizer Application: Fertilize again six to eight weeks after the April application. Use a slow-release fertilizer to provide consistent nutrition throughout the late spring and early summer months in your do it yourself lawn care program.
Weed Management: Address weeds proactively. Manually pull dandelions and other broadleaf weeds, spot-treat affected areas with a post-emergent herbicide, or consider a lawn-wide treatment if weed pressure is significant.

Mowing and Watering Adjustment: Continue to mow and water warm-season grasses until they naturally begin to turn brown, signaling the onset of dormancy. Gradually reduce watering frequency as temperatures cool.
Final Fertilizer for Root Growth: When warm-season grasses begin to green up again slightly with cooler temperatures (often in late September), apply a final dose of fertilizer to support root growth before full dormancy. This late-season feeding is beneficial for root health and spring green-up.

October to November: Winter Dormancy Prep for Southern DIY Lawns

Wind down your do it yourself lawn care routine as grass growth slows significantly, preparing your lawn for winter dormancy.

Winterizer Fertilizer: Apply a final winterizer fertilizer to further support root health during dormancy. Choose a formula that is lower in nitrogen and higher in potassium and phosphorus to promote root strength and winter hardiness.
Mowing Until Dormancy: Continue mowing until the grass completely stops growing. Gradually lower the mowing height with each subsequent mow as growth slows.
Leaf Management: Rake leaves diligently to prevent them from smothering the dormant grass. Good air circulation is important even during dormancy to minimize disease issues and prepare for spring regrowth, ensuring your do it yourself lawn care program sets you up for success next season.
