Tree and shrub fertilization is a necessity in our urban landscapes. Nutrient recycling that takes place in the natural environment for trees and shrubs is lacking in the urban environment. The spring, fall and perfect clean-ups of our properties to keep the lawn neat and tidy, eliminates the natural process of nutrient recycling. Urban trees, especially older ones are simply starving to death because of the minimal necessary nutrients available within our landscapes. Without the essential nutrients that the plants require being readily available, we must artificially compensate for this. Major nutrients such as Nitrogen, Phosphorus and Potassium, are in demand for mature trees to survive under our already stressful, compacted and poorly drained soils. Micronutrients like Iron, Manganese and Zinc are just as important for the health and vigor of many species, but are required in lesser quantities. An added bonus is during the fertilization process the soil is also being aerated by the injection process.

Deep Root Fertilization
This photo is an example of Hydraulic Injection Fertilization. A Root Feeder probe is inserted into the soil 14-16 inches deep and a water suspended formula fertilizer is injected into the ground by means of hydraulic pressure aerating the soil at the same time. This process has minimal damage to the surrounding landscape leaving only a dime sized hole where the injection is completed. The formula is safe and harmless to children and pets.

Organic fertilizers are in common demand today, due to the consciousness of conserving the purity of nature and our surroundings. If too much fertilizer is applied in one area, the results can lead to root burn caused by a high salt index in the soil in that particular area. A controlled release or slow release, as it is sometimes called, is the recommended choice by most Arborists. This type of fertilizer is also beneficial due to the fact that it is ready to be absorbed by the roots in small amounts over a long period of time, minimizing 'leaching', which is when the nutrients are washed away before they can be absorbed by the roots.
