Winterizing in Washington

As temperatures drop and rain turns to frost, preparing your landscape for winter is one of the most important steps you can take to protect your investment. Washington’s winters bring steady moisture, occasional freezes, and long stretches of shade—all of which can stress lawns, plants, and irrigation systems if left unchecked.

Here’s how to get your property ready for the colder months ahead.

Why Winterizing Matters

Winterizing isn’t just about surviving the cold—it’s about setting your landscape up to thrive once spring returns. Proper winter prep helps prevent costly damage from frozen pipes, root rot, compacted soil, and nutrient loss. It also protects your plants, turf, and hardscapes from the wear and tear caused by heavy moisture and temperature swings.

When done right, winterizing ensures your lawn stays healthy, your irrigation system runs efficiently, and your outdoor space rebounds quickly when the season changes.

Key Steps to Winterize Your Yard

Here are a few expert-approved steps we recommend before winter settles in:

1. Shut Down and Drain Irrigation Systems

Water left in pipes or sprinkler lines can freeze and cause cracks or bursts. Always have your irrigation system professionally blown out to prevent damage.

2. Final Lawn Care Tasks

Give your grass one last mow—around 2.5 inches high—and apply a slow-release winter fertilizer rich in potassium to strengthen roots through the cold. Remove leftover leaves and debris to prevent mold and moss buildup.

3. Protect Plants and Shrubs

Wrap tender plants or young trees with burlap or frost cloth, especially those in exposed or windy areas. Add mulch around roots to lock in warmth and moisture.

4. Clean and Store Outdoor Furniture

Moisture can damage patio furniture, cushions, and decor. Clean and store them in a dry place or under protective covers.

5. Check Drainage and Gutters

Clogged gutters or poor drainage can lead to pooling water, erosion, and even foundation issues. Clear leaves, test runoff areas, and ensure downspouts direct water away from your home and garden beds.

Common Winter Challenges in Washington Landscapes

• Heavy rainfall: Leads to over-saturation and erosion if drainage isn’t maintained.

• Freeze-thaw cycles: Can cause cracking in hardscapes or exposed pipes.

• Limited sunlight: Encourages moss growth and slows plant recovery.

• Wind exposure: Dries out evergreens and damages fragile branches.

Addressing these challenges early ensures your landscape stays safe, functional, and beautiful all winter long.
