Give Your Trees the Boost They Need: The Benefits of Deep Root Fertilization

If your trees are looking tired, sparse, or are growing slower than they used to, it might be time to look below the surface—literally.

Healthy trees start with healthy roots, and one of the best ways to support those roots is through deep root fertilization. At Timberline Arborists, we offer professional deep root fertilizing services designed specifically for trees in Southern Alberta’s challenging climate.

What Is Deep Root Fertilization?

Deep root fertilization is the process of injecting a custom-blended liquid fertilizer directly into the root zone of your trees using a pressurized wand. This delivers nutrients exactly where your trees need them—beneath the compacted surface soil where traditional fertilizers can’t reach.

Why Your Trees Need It

Southern Alberta’s dry conditions, high winds, and nutrient-depleted soils can be tough on trees, especially in urban and suburban yards where roots are often compacted by foot traffic or construction. Deep root fertilizing helps by:

  • Improving soil structure with added organic matter

  • Delivering essential nutrients like nitrogen, phosphorus, and potassium directly to the root zone

  • Boosting tree health and resilience, especially against drought and disease

  • Encouraging vigorous growth of both roots and foliage

  • Reducing stress from pruning, pests, and environmental pressures

The Best Time to Fertilize

In our region, spring and fall are ideal for deep root fertilization. Spring feeding helps trees wake up strong after winter, while fall feeding boosts root development before dormancy. Both treatments help your trees store the energy they need to thrive.

Custom Solutions for Every Tree

At Timberline Arborists, we don’t believe in one-size-fits-all. Our ISA-certified arborists assess each tree’s needs and blend our fertilizer with soil biology boosters like live microbial inoculants, ensuring your trees don’t just survive—they flourish.
