1. Know Your Grass Type & Location

• Cool-Season Grasses (Bluegrass, Rye, Fescue – common north of St. Louis):
  
• Spring & Fall: 2″–2½″ for optimal growth
  
• Summer: Raise to ~3″ to reduce heat stress
  
  
• Warm-Season Grasses (Bermuda, Zoysia, Bahiagrass – typical in Oklahoma):
  
• Spring/Fall: 1″–2″—they tolerate shorter heights well
  
• Summer: Consistent 1″–2″ works for vigorous growth

2. Measure & Adjust Correctly

• Deck height numbers may not match actual cut—test by mowing a small patch and measuring it.
  
• Follow the 1/3 Rule: Never remove more than one-third of the grass blade per mowing.
  
• Aim for trimming no more than 1″ at a time during peak growth. Multiple sessions per week may be ideal during spring and fall.

3. Caring for New Grass Seed or Sod

• Sod: Wait at least 10 days or until vigorous growth before mowing.
• Seed, Plugs, or Sprigs: Let grass reach 3"-4" tall before the first cut.

4. The Case for Tall Grass

• Taller grass provides shade, retains soil moisture, and builds deep roots.
  
• It grows slower, leading to fewer mows—saving you up to 20% of mowing time annually.
• It also reduces weed intrusion—less need for herbicides!
  

5. Why Cutting Too Short Harms Your Lawn

• Short cuts stress grass and force it to use root reserves, weakening the plant.
  
• Shallow roots dry out faster and are less resilient to drought and heat.
  
• Tall grass = deeper roots, better health, and a greener lawn.
  

💡 Final Takeaway

• Identify your grass and know your zone (warm vs. cool season).
  
• Aim for 1″–2½″ based on grass type and season.
  
• Avoid cutting more than 1/3 of grass at a time.
  
• Leave new lawns longer until established.
  
• Choose height that supports depth, strength, and overall lawn health.
