Winterizing Lawn and Irrigation

Title: Lawn Winterization

Grass Winterization and Irrigation Winterization Best Practices


As winter approaches, it's essential to prepare your lawn and irrigation system for the colder months, especially if you have Bermuda grass. Bermuda grass is a warm-season grass that thrives in the summer but goes dormant during the winter. Proper winterization helps ensure the health of your lawn and irrigation system, so they're ready to flourish when spring arrives. In this blog post, we'll discuss Bermuda grass winterization and irrigation winterization best practices.

Bermuda Grass Winterization

Bermuda grass, with its lush green appearance during the summer, requires some specific care to endure the winter months. Proper winterization helps protect it from the cold and keeps it healthy. Here are some essential steps:

1. Mowing and Trimming: Before winter sets in, give your Bermuda grass a final mow, ensuring it's not too short or too tall. A height of around 1 to 1.5 inches is ideal. Trim any overhanging branches that may shade your lawn during the winter months.

2. Fertilization: Apply a balanced, slow-release fertilizer in late fall to provide essential nutrients to your Bermuda grass during its dormancy. Avoid high-nitrogen fertilizers, as they can encourage new growth that is vulnerable to frost damage.

3. Weed Control: Eliminate weeds from your Bermuda grass lawn before winter. Weeds can compete for nutrients and water, potentially weakening your grass. Consider using a pre-emergent herbicide in early fall to prevent winter weeds.

4. Watering: Reduce the frequency and duration of watering as temperatures drop. Bermuda grass doesn't need as much water during the dormant season. Water deeply but infrequently to help prevent disease and fungal issues.

5. Pest and Disease Management: Keep an eye out for pests and diseases that can affect Bermuda grass during the winter. Apply appropriate treatments if needed.

Irrigation Winterization Best Practices

Winterizing your irrigation system is equally important to prevent damage from freezing temperatures. Here's how to do it effectively:

1. Drain the System: Begin by turning off the water supply to your irrigation system. Then, use the system's manual drain valves or automatic drain feature (if available) to remove water from the pipes and sprinklers. This step prevents freezing and potential pipe damage.

2. Blow Out the Lines: Hiring a professional to blow out the irrigation lines using compressed air is highly recommended. They will remove any remaining water, preventing costly damage to the pipes and valves.

3. Insulate Valves and Backflow Preventers: Wrap any exposed valves and backflow preventers with insulation or insulating covers. This additional layer of protection helps safeguard these critical components from freezing.

4. Disconnect and Store Hoses: Disconnect garden hoses from outdoor faucets and store them indoors. This prevents freezing and bursting of the hoses and faucets.

5. Programmable Controllers: Adjust your irrigation controller to a "rain" or "off" mode for the winter. Ensure that no watering schedules are active during the cold months.

6. Regular Maintenance: Regularly inspect your irrigation system throughout the winter to ensure everything remains in good condition. Address any issues promptly to prevent further damage.


Proper winterization of Bermuda grass and your irrigation system is crucial to maintain a healthy lawn and prevent costly damage. By following the steps outlined in this blog post, you can ensure that your Bermuda grass remains in good shape during its dormant period and that your irrigation system survives the winter intact. Come spring, your lawn will be ready to flourish once again, thanks to your careful winterization efforts.
