Why Grass Goes to Seed: Stress Response, Not Mower

Seedhead Formation Explained

Kentucky bluegrass produces seedheads under stress—heat, drought, nutrient deficiency, or improper mowing. Your new riding mower coincides with summer stress period, not causation. Neighbor's different grass blend or better watering explains his lack of seedheads.

Management Response

1. Raise mowing height to 3 inches
2. Mow frequently (≤1/3 blade removal)
3. Deep water (1 inch weekly)
4. Seedheads will disappear in 2-3 weeks as conditions improve

Key Facts

• Seedheads don't germinate this season (wrong conditions)
• Mowing doesn't prevent seedhead initiation—it's physiological
• Stress reduction is the only solution
• Different bluegrass cultivars vary in seedhead propensity
