Root Work & Soil Improvements

The conditions around those roots make all the difference. Even trees of the same species grow very differently in urban landscapes than they do in the wild. In the forests of the Pacific Northwest, trees thrive within complex ecosystems. The soil is naturally loose and rich, covered in leaf litter that’s constantly broken down by insects and small animals. This living layer keeps the soil aerated, insulated, and full of moisture and nutrients — the perfect environment for roots to grow and breathe.

Urban and suburban soils on the other hand are often compacted during construction and further compressed by foot traffic and maintenance. When we rake away leaf litter and keep our landscapes “tidy,” we remove the natural mulch and nutrients that trees depend on. Over time, the soil becomes hard and barren, and roots struggle to form the fine fibrous roots that absorb water and nutrients. Without these feeder roots, trees lose vigor, grow slowly, and become more vulnerable to stress.

If your tree is struggling, the best way to help it recover is to encourage new fibrous root growth. We can do this through pneumatic tilling and mulching — a process that restores soil structure and vitality. First we decompact the soil

1. Decompaction: Using a specialized air tool, we gently loosen the soil around the tree to a depth of 8–12 inches without damaging roots.
2. Amendment: We add compost, biochar, and other organic materials to enrich the soil.
3. Incorporation: The air tool is used again to blend these amendments into the soil, creating a soft, nutrient‑rich environment that mimics a natural forest floor.

This process can be safely performed around existing garden plants and near underground utilities such as irrigation or lighting systems.

There’s no better starting point for improving a tree’s health than restoring its root environment. Pneumatic tilling and mulching rebuild the soil ecosystem, helping your tree regain strength, resilience, and long‑term vitality.
