# Details:

Overall, I’m happy with my lawn, but I’ve consistently struggled with a middle patch in the backyard that just won’t grow. I've included pictures of the backyard and front yard for reference.

**Site & Background**

* Zone 6A — Southeast Denver
* Third growing season; added sod in year one to part of the problem area
* Two large dogs play in that area a lot — could traffic be the main issue?
* The affected patch shifts depending on the month — maybe sun scorch?

**What I’ve Tried So Far**

* **Sprinkler audit (June):**
   * Tech suspected disease from rabbit feces → applied 2 rounds of Immunox, 2 weeks apart
   * Increased nozzle size and repositioned heads to match slope and improve coverage
   * Adjusted watering schedule by month and heat
   * Recommended stopping Sunday Lawn Care subscription and switching to Scotts Weed & Feed + Turf Builder **Triple Action**
      * Completed 2 rounds of Weed & Feed, 5 weeks apart
   * Said aeration here doesn’t help much unless overseeding

**Next Steps**

* Purchased Tenacity + Triclopyr, planning to apply as a pre-emergent next season

**Questions:**

* Is dog traffic the biggest culprit here?
* Could this be sun scorch since the patch moves around?
* Any other tips before I go into next season?
