Fertilization is an important aspect of a PHC program.  Trees and shrubs in the urban landscape are often growing in less than perfect soil.  Fallen leaves and plant material, rich sources of nutrients, are raked up and disposed of, and overtime, urban soils become depleted of the nutrients required for sustained healthy tree growth.

Fertilizing is an easy way to add those essential nutrients back to the soil. The Tree Specialists, Inc utilizes a deep root soil injection method of fertilizing - a process of injecting liquid fertilizer 8 to 12 inches into the ground under pressure. We use a one-year slow release fertilizer that contains nitrogen, phosphorus, potassium and trace elements. By using this method, we feed all of the roots, aerate the soil, and provide the tree with nutrients over one complete year.
