Prepping Your Landscape For Fall


With autumn’s arrival in Colorado, the vibrant summer landscape slowly transitions into a panorama of gold and russet tones. Fall in Colorado is unpredictable; hence, preparing your landscape for the impending winter is crucial to ensure a healthy and thriving garden come spring. Follow this comprehensive guide to safeguard your garden from Colorado’s harsh and fluctuating fall conditions.

1. Protect Your Perennials

Perennials form the backbone of most Colorado gardens. These plants will return year after year if given appropriate care during the fall.

  • Mulching: After the first frost, apply a generous layer of organic mulch around perennials. Mulch insulates the soil, protecting the plants’ root systems from the freezing and thawing cycles.
  • Pruning: Trim dead foliage to prevent diseases, but leave some to protect the plants from the cold.
  • Watering: Keep the soil consistently moist but not waterlogged. This helps plants withstand the dry and cold winter.

2. Lawn Care

Your lawn requires attention and protection from the chilly winds and frost of fall.

  • Aeration: Aerating your lawn allows water, oxygen, and nutrients to reach the grass roots, promoting a healthier lawn in the spring.
  • Fertilization: Apply a fall fertilizer rich in potassium and phosphorous to strengthen the roots and increase cold tolerance.
  • Mowing: Continue to mow your lawn but adjust the mower’s height to leave the grass slightly taller. Taller grass is more resilient to cold and traffic.

3. Tree and Shrub Maintenance

Trees and shrubs are significant investments in your landscape, and they need specific care to survive the winter intact.

  • Wrapping: Young and thin-barked trees should be wrapped with tree wrap to prevent sunscald and frost cracks.
  • Pruning: Remove dead or diseased branches to improve the tree’s health and appearance. However, extensive pruning is best left for the dormant winter season.
  • Watering: Provide deep watering until the ground freezes to keep them hydrated through the winter.

4. Fall Planting

Fall is an excellent time for planting trees, shrubs, and spring-blooming bulbs in Colorado.

  • Trees and Shrubs: Planting in the fall allows these plants to establish their root systems in the cooler and moister soil conditions.
  • Spring-Blooming Bulbs: Plant bulbs like tulips and daffodils in the fall for a colorful display in the spring.

5. Winterize Irrigation Systems

Preventing freeze damage to your irrigation system is vital.

  • Drain and Blow Out: Remove all water from the pipes, sprinkler heads, and valves to prevent freezing and cracking.
  • Insulate: Cover valve boxes and above-ground pipes with insulation to provide extra protection from freezing temperatures.

6. General Cleanup

A clean garden is a healthy garden.

  • Remove Annuals: Once they have completed their life cycle, remove annual plants.
  • Clear Debris: Leaves and other debris can harbor pests and diseases. Regularly clear them away from your garden beds and lawn.
  • Organize and Store Garden Tools: Clean, sharpen, and store your gardening tools properly to prolong their life and efficiency.


Fall landscape preparation in Colorado involves thoughtful planning and execution to ensure your garden can withstand the winter months and flourish in the spring. By following these fall gardening tips, you will not only protect your investment but also create a landscape ready to wake up healthy and vibrant when warmer weather returns. Happy gardening!
