Fertilizing and Soil Improvements

The average urban tree only lives between 19 and 28 years, that’s a far cry from the potential age of many native species. Think about the loss in terms of environmental, economic and aesthetic deficit and the magnitude grows even more.

Compare our urban soils to the soil found in a forest environment. Soil in an undisturbed forest environment is considered to be in its best natural state. The porous soil allows required water and air down to the root systems and the biodiversity of animals in the soil and the organic duff layer creates sustainable soil for trees. Soil compaction is the most common problem for trees in urban areas.

Fertilizing and soil improvements

It’s time we started to pay more attention to the tree below grade…the root system. Traditionally we have used chemical fertilizers to help offset the lack of natural nutrients in the soil. The application of chemical fertilizer is a short-term solution that does not improve the long-term health of the soil, and can have an impact on the surrounding environment through nutrient leaching.

In forest soils, which are sustainable, there is a biodiversity of animals, from single cell organisms to earthworms. These animals have a sustainable food source, organic material from the trees and their natural life cycles. This natural balance creates the perfect environment for tree roots. Our Organics Program helps to recreate this sustainable condition.

  • Evaluate current conditions of existing trees and prescribe treatment.
  • Improve soil conditions by fracturing the soils surrounding the planting hole, using an Air Knife, allowing the new roots to penetrate these soils.
  • Root flare excavation, using the Air Knife, to expose girdling roots, which can then can be properly pruned.
  • Add organic material to the soil over the root system preferably in the form of composted wood chip mulch.
This program has been introduced by Maple Hill Tree Services in response to address the need to manage our urban environment in a sustainable and responsible manner. This is a landscape health approach which seeks to create sustainable landscapes through increased biodiversity above and below ground.
  • Improve landscape health and sustainability
  • Increase biodiversity in the landscape
  • Reduce water requirements and nutrient inputs
  • Fracturing of the soil if deemed compacted by field test
  • Addition of compost and/or composted mulch to increase water holding capacity, pore space, provide food for micro organisms etc
  • Application of compost tea, a specialized blend of compost that provide large numbers of micro organisms to soils that are lacking
  • Organic nutrient amendments as needed based on soil sample results
