A Complete Guide to Our 2026 Tree Care Program in Sun Valley, Idaho

May 28, 2026

In the Wood River Valley, trees face a unique set of challenges. From long winters and compacted soils to hot, dry summers, maintaining healthy trees requires more than occasional watering or trimming. It requires a thoughtful, seasonal approach that supports the soil as much as the tree itself.

At Mountain Valley Compost & Tree Care, our 2026 Tree Care Program is designed to do exactly that. Built around proven organic practices and tailored to our mountain environment, this program focuses on improving soil biology, strengthening root systems, and supporting long-term tree health through every stage of the year.

Why Soil Health Is the Foundation of Tree Care

Healthy trees begin below the surface. Soil is not just dirt, it is a living ecosystem filled with microorganisms that play a critical role in nutrient cycling, water retention, and root development.

When soil biology is weak or depleted, trees struggle to access the nutrients they need, even if those nutrients are present. This can lead to slow growth, increased susceptibility to pests, and overall decline.

Our program centers around rebuilding that biological system using compost tea, mycorrhizal fungi, and nutrient-rich organic inputs that bring the soil back to life.

Spring Application (April / May): Building the Foundation

The first step in our program begins in early spring, when trees are just starting to come out of dormancy.

During this phase, we apply:

Compost tea brewed with vermicast (worm castings)
Mycorrhizal fungi

This combination introduces beneficial microorganisms and humic acids into the soil. These elements work together to:

Improve soil structure and biology
Increase nutrient availability
Support early root and canopy development

Spring is one of the most important times to treat your trees. What happens at the start of the season directly impacts how well they perform throughout the rest of the year.

Summer Applications (June & August): Nutrient Loading and Stress Support

As temperatures rise and trees enter their peak growing season, their demand for nutrients and resilience increases.

Our summer treatments, applied in June and August, are known as the nutrient loading phase. These applications include compost tea brewed with:

Vermicast (worm castings)
Myco Chum, a blend of molasses, fish hydrolysate, liquid kelp, and humic acids
King Crab
Mycorrhizal fungi

This blend provides a readily available food source for beneficial soil microbes, which in turn support the tree’s ability to absorb nutrients and retain moisture.

In the Wood River Valley, where summer heat and dry conditions can stress even established trees, this step is essential. It helps trees maintain strength, resist environmental stress, and continue healthy growth through the toughest part of the season.

Fall Application (September / October): Recovery and Preparation

As the growing season comes to an end, trees begin shifting their energy back into their root systems.

Our fall application mirrors the spring treatment and includes:

Compost tea brewed with vermicast
Mycorrhizal fungi

This final step helps:

Replenish nutrients depleted during the growing season
Strengthen and expand root systems before winter
Prepare trees for a strong start the following spring

Fall treatments are often overlooked, but they play a critical role in long-term tree health. Skipping this step can leave trees underprepared for winter conditions and slow to recover in the spring.

Soil & Tree Restoration for Stressed or Declining Trees

Not all trees require the same level of care. For trees showing signs of stress, decline, or poor growth, we offer customized restoration treatments.

These programs may include:

Higher application volumes
Increased frequency of treatments
Targeted nutrient and microbial support

Each restoration plan is tailored to the specific condition of the tree and the surrounding soil. In many cases, trees that appear to be failing can recover when the underlying soil issues are properly addressed.

Transparent Pricing and Custom Plans

Our current rate is $2.30 per gallon, with total project costs depending on:

Property size
Location
Scope of work

Because no two properties are the same, we take the time to evaluate your landscape and recommend a plan that fits your needs.

A Year-Round Approach That Delivers Real Results

Tree care is not a one-time service. It is an ongoing process that evolves with the seasons.

Our 2026 Tree Care Program is built around four key applications, each designed to support your trees at the exact moment they need it most. From spring soil activation to summer resilience and fall recovery, every step works together to create healthier soil and stronger trees.

If you are looking for a natural, effective way to improve your landscape and protect your investment, this program offers a proven path forward.
