WHAT TO EXPECT WITH DORMANT BERMUDAGRASS ON THE COURSE

BY LOU SILVEIRA GOLF COURSE SUPERINTENDENT

This time of year, you may start noticing changes in the appearance and growth of the bermudagrass on our tees, fairways, and roughs. These seasonal changes are natural — the bermudagrass is entering dormancy. Here are some insights into what this process entails, what you can expect to see, and the care we’re taking to ensure optimal course conditions.

Understanding Dormancy in Bermudagrass

Bermudagrass is a warm-season grass that thrives in spring and summer. As temperatures drop, it enters dormancy, protecting itself from colder weather. Dormancy begins when soil temperatures dip below 50°F, typically in late fall. During dormancy, the grass “shuts down,” reducing its growth and shifting its energy away from producing new green blades.

Visual Changes on the Course

1. Color Shift: As bermudagrass goes dormant, it will gradually change from vibrant green to a light brown or tan color. While this may appear to be a sign of poor health, it is actually the grass conserving its resources. Dormant bermudagrass is not dead – it’s simply in a resting phase, much like trees shedding leaves in autumn.

2. Slower Growth and Firmer Conditions in between rainstorms: With the grass no longer actively growing, you’ll notice the fairways and roughs become firmer and may provide more roll on your shots. This seasonal firmness can be advantageous for playability, as you’ll experience a faster course with less divot damage.

3. Thin Appearance in Certain Areas: Some high-traffic areas may appear a bit thin or patchy as the bermudagrass becomes dormant. We will be taking steps to minimize any issues in these areas and to maintain a consistent playing surface.

Maintenance Adjustments During Dormancy

Our grounds crew will be making several adjustments for the dormant grass and keep the course in top shape:

• Reduced Mowing Frequency: With less growth occurring, mowing frequency will decrease. This will help preserve the grass during dormancy and ensure a smoother transition into the active growing season next spring.

• Protection of Turf Health: We’ll be mindful of potential winter stressors, such as frost, and take steps to manage these challenges. Frost delays will likely be more common to prevent turf damage, and we ask for your patience as we allow the course to recover on chilly mornings.

What to Expect Moving into Spring

When spring arrives, the bermudagrass will transition out of dormancy as temperatures warm up, resuming active growth and gradually restoring its green color and lush appearance. Our team will monitor the turf health closely throughout the dormant period to ensure it is strong and vibrant next season.

Thank you for your continued support and understanding as we navigate these seasonal transitions. Our team is committed to providing you with the best playing conditions year-round, and we look forward to seeing you out on the course enjoying all that Woodbridge has to offer.
