Care for fine fescue in Idaho
Fine fescues tolerate shade and low fertility well, but they can go dormant in summer heat and are easily overwatered or overfed.
Recommended timingSpring through fall
What to do
- Mow roughly 2–2 1/2 inches high and avoid scalping shaded or heat-stressed turf.
- Water based on soil moisture and weather, recognizing that temporary summer dormancy can be normal for fine fescue.
- Keep fertility light. University of Idaho guidance generally emphasizes spring and late-summer or early-fall applications rather than summer feeding.
- Reduce traffic in shaded or dormant areas and overseed thin spots with a shade-appropriate compatible mix when conditions are favorable.
- Confirm that decline is not caused by excessive moisture, poor drainage or a grass type unsuited to the light level before applying a product.
Use a soil test and exact product label before applying fertilizer or pesticide, and avoid unnecessary chemical treatment of dormant turf.
