In an urban landscape, trees do not need all the necessary nutrients as it would in their natural habitat. Seasonal fertilization is recommended and this is how we do it:

STEP 1: Fertilization
In the spring or fall the soil around the tree will be fertilized with a custom selection of the following: Nitrogen (N), Phosphorus (P), Potassium (K), Iron (Fe), Manganese (Mn), and liquid compost – all essential nutrients for healthy soil and root systems. Providing the tree with the best soil chemistry is the goal.
STEP 2: Metabolic Processes
Trees acquire carbon, hydrogen, and oxygen from the atmosphere and water and through photosynthesis (light energy from the sun), they are combined to produce glucose. Trees use glucose and essential nutrients for growth, reproduction, and pest/disease resistance.
STEP 3: Evapotranspiration
This process involves the movement of nutrients from the soil, up the trunk, and into the outer canopy, carrying them dissolved in water to be used as needed.
STEP 4: Reduced Nutrient Levels
Essential nutrients in urban soils can be depleted for several reasons, and this leads to limited metabolic processes. Fertilization helps maintain nutrient availability to trees. BACK TO STEP 1.
