10 reasons your lawn is turning yellow — and how to fix it
Dr. Russell Sharp of Eutrema walks through the top 10 reasons lawns and sports turf turn yellow (chlorosis), explaining the science behind the symptom and showing how common issues — drought, nutrient deficiency, compaction, scalping, blunt mower blades, fungal disease, pests, pH imbalance, pet urine, and competition from trees/weeds/moss — produce yellowing.
The episode gives straightforward, practical fixes: deep infrequent watering, correct nitrogen and iron treatments, liquid gypsum for compaction and urine damage, sharpen blades, pest control, pH adjustment, and targeted fungicide or wetting-agent solutions.
