Your Year-Round Plan for a Lush Treasure Valley Lawn
Maintaining a beautiful, healthy lawn in Boise, Meridian, or Nampa requires more than just occasional mowing and watering. The Treasure Valley’s unique semi-arid climate, with its hot, dry summers and cold winters, presents specific challenges. A proactive, year-round approach is essential for a yard that not only survives but thrives. This guide provides a clear, season-by-season plan for expert Boise lawn maintenance, ensuring your grass stays vibrant and resilient all year long.
Spring Lawn Care (March – May): Waking Up Your Yard
As the snow melts and temperatures rise, your lawn begins to emerge from dormancy. This is a critical time to set the stage for a successful growing season.
- Yard Cleanup: Gently rake away leaves, twigs, and any other debris that has accumulated over the winter. This initial step is crucial for preventing mold and disease while allowing sunlight and air to reach the soil.
- Fertilization & Weed Control: Early spring is the perfect time for a balanced, slow-release fertilizer to give your turf the nutrients it needs to green up quickly. This is also the most effective window to apply a pre-emergent herbicide, which creates a barrier to stop crabgrass and other weeds before they can germinate. Our Barefoot Lawn Care Program is expertly timed for these vital applications.
- Core Aeration: The clay-heavy soil common in our area is prone to compaction. Spring core aeration is a game-changer, pulling small plugs of soil to allow oxygen, water, and nutrients to penetrate deep into the root zone.
- Sprinkler System Startup: Before the summer heat arrives, it’s essential to reactivate your irrigation system. A professional sprinkler service can check for leaks, adjust heads for optimal coverage, and ensure your system is ready for the demands of summer.
Summer Lawn Care (June – August): Surviving the Heat
Boise’s hot, dry summers can be incredibly stressful for the cool-season grasses, like Kentucky bluegrass and fescue, that are common here. The goal during these months is to maintain health and build resilience.
- Smart Watering: Water deeply but infrequently, about two to three times per week. This encourages roots to grow deeper, making the lawn more resistant to drought. The best time to water is in the early morning to minimize evaporation.
- Adjust Mowing Height: Raise your mower blade to about 3 inches. Taller grass blades provide shade for the soil, which helps retain moisture and suppress weed growth.
- Pest & Grub Control: Summer is when pests like billbugs and grubs can cause significant damage, often appearing as brown patches that don’t improve with watering. A preventative grub control treatment is the best defense against these destructive insects.
Did You Know?
Much of the soil in the Treasure Valley is alkaline, which can make it difficult for grass to absorb essential nutrients like iron. This is why a consistent, professional fertilization schedule is so important for Boise lawns—it provides the specific nutrients your turf might be missing.
Fall Lawn Care (September – November): Preparing for Success
Autumn is arguably the most important season for lawn maintenance in Boise. The cooler temperatures and increased moisture create the ideal environment for your lawn to recover from summer stress and store nutrients for winter.
- The Most Important Fertilization: A fall “winterizer” fertilizer application is the most crucial feeding of the year. It promotes strong root development and provides the nutrients needed to survive the cold and green up rapidly next spring.
- Ideal Aeration Window: If you didn’t aerate in the spring, fall is another perfect opportunity. It alleviates summer soil compaction and prepares the ground for fertilization, ensuring nutrients reach the roots where they’re needed most.
- Sprinkler Blow-Out: This is an non-negotiable task in Idaho. Before the first hard freeze, your irrigation system must be professionally winterized. A sprinkler blow-out uses compressed air to clear all water from the lines, preventing frozen pipes and costly repairs.
- Leaf Removal: Keep up with raking fallen leaves. A thick layer of leaves can smother the grass, block sunlight, and invite pests and diseases.
Winter Lawn Care (December – February): Rest and Protect
While your lawn is dormant, a few simple actions can protect it through the cold months.
- Minimize Foot Traffic: Try to avoid walking on your frozen lawn. The brittle, frozen grass blades can break easily, leading to damaged spots in the spring.
- Focus on Trees: Winter is an excellent time for certain types of professional tree maintenance, such as applying dormant oil treatments. These applications help control overwintering insects and their eggs, protecting your valuable trees and shrubs.
- Plan for Next Season: Winter is the perfect time to assess your lawn’s needs and schedule services for the upcoming year to ensure you get a spot on the calendar.

Frequently Asked Questions
How often should I water my lawn during a Boise summer?
For established lawns, the best practice is deep and infrequent watering, typically 2-3 times per week. The goal is to apply about one inch of water per week in total. Watering in the early morning hours is most efficient.
When is the best time to aerate my lawn in Idaho?
The best times for core aeration are during the active growing periods for cool-season grasses: spring (April-May) and fall (September-October). Fall is often considered the best time as it helps the lawn recover from summer stress and prepare for winter.
What are the signs of grub or billbug damage?
Signs of grub and billbug damage include irregular brown patches of dead grass that do not green up with watering. The turf may feel spongy and pull up easily like a carpet, revealing the C-shaped white grubs in the soil beneath.
