After a long Indiana winter, your lawn is ready for a fresh start. Spring is your window of opportunity to strengthen your grass, stop weeds early, and build a lawn that stays healthy all year. If you’re wondering where to begin, this step-by-step spring lawn care checklist will walk you through exactly what your lawn needs—and when it needs it. 

Step 1: Clear the Way for New Growth

Your first task is simple but important—clean up your lawn. Winter debris, like leaves, twigs, and dead grass, can block sunlight and trap moisture, creating the perfect environment for disease. 

A light rake will: 

• Remove buildup from winter  
• Improve airflow across your lawn  
• Help the new grass grow evenly  

Be gentle during this step to avoid damaging tender spring growth. 

Step 2: Check Your Soil Before You Treat

Healthy lawns start from the ground up. Before applying fertilizer, it’s smart to understand what your soil actually needs. That’s where soil testing comes in handy. Soil testing is your lawn’s annual bloodwork – it helps identify nutrient deficiencies and current pH levels. 

It helps homeowners apply the correct nutrients and avoid unnecessary treatments. Purdue University offers soil sample testing and also shows the proper way to collect a soil sample.  

Knowing your soil’s condition allows you to: 

• Balance pH levels  
• Target nutrient deficiencies  
• Improve overall lawn performance  

Step 3: Feed Your Lawn the Right Way

Once you’ve identified what your lawn is missing, it’s time to feed! Spring fertilization gives your lawn the nutrients it needs to green up and grow stronger. However, more is not always better. Cool-season grasses like Kentucky bluegrass and fescue respond best to moderate feeding in spring. If you’re unsure about the best fertilizer schedule for your lawn, we can help! We offer lawn fertilization programs that are designed for Indiana grass types and the climate. 

Step 4: Stop Weeds Before They Start

If you want fewer weeds this year, spring is the time to act. A pre-emergent herbicide creates a barrier that prevents weed seeds from sprouting. Timing is everything—apply when soil temperatures reach about 55°F. 

Already seeing weeds? Use a post-emergent treatment early while they’re easier to control. 

Step 5: Adjust Your Mowing Habits

As your lawn starts growing faster, mowing becomes a regular task. How you mow can make a big difference in your lawn’s health. Taller grass helps shade the soil and naturally reduces weed growth. Mowing the lawn too short can cause weaker root systems and stress to the lawn.

Smart Mowing Tips: 

• Keep grass height between 2.5–3 inches  
• Never cut more than one-third of the blade  
• Keep mower blades sharp for clean cuts  

Step 6: Water for Strong Roots

Spring rains help, but consistent watering ensures your lawn develops deep, healthy roots. When you water is just as important as how much you water. Deep watering encourages stronger root systems and improves drought tolerance.

Watering Best Practices: 

• Water deeply, not frequently  
• Aim for about 1 inch per week, including rainfall
• Water early in the morning to avoid evaporation during peak temperatures  

Step 7: Loosen Compacted Soil

If your lawn feels hard or water tends to sit on the surface, compaction may be limiting growth. While fall is often the best time to aerate cool-season grasses, spring aeration can benefit heavily compacted lawns. 

Lawn aeration helps by: 

• Allowing air and water to reach roots  
• Improving nutrient absorption  
• Encouraging deeper root development
