Hi Richard!

Yes, turf mites can definitely be a concern given the dry fall and winter we’ve had. Mites become problematic when turf is drought-stressed and less healthy, which makes it more vulnerable to pests and disease. Healthy turf is much more resilient.

The easiest and most effective way to reduce the risk of mites is through fall and winter watering.
When to water: Wait until air temperatures are above 40°F and expected to stay above freezing for several hours so the water can soak in.
How much: Aim for about 1 inch of water per square foot of lawn per month, including any precipitation.
Example: If you get 0.2 inches of rain, water about 0.8 inches.
How to apply: Spread watering out so the soil absorbs it without pooling. Deep, slow watering is best.

This practice will help keep turf healthy and reduce pest pressure in spring.
