Our ReLeaf deep root tree fertilization program usually consists of 2 applications per year, one in the spring and one in the late summer/early fall. We use a custom made, water soluble fertilizer with micronutrients. This special blend is formulated specifically for our climate and conditions. This non-burning, low nitrogen fertilizer promotes strong, vigorous and even growth. This fertilizer is designed to battle against the high PH found in Calgary’s soils to ensure trees are able to take up and absorb the nutrients they need. This water based solution is injected below the soil surface to the tree’s roots in a form that reduces the chance of root burn and encourages uniform uptake in the tree. It also bypasses shallow rooted grass and perennial root systems that take up much of surface applied fertilizers. Some situations that may benefit from a tree fertilization program include:
- Young trees requiring some support during establishment
- Trees with poor colour due to a nutrient deficiency
- Trees in poor soil conditions
- Trees and shrubs overcoming insect infestations or diseases
