Prescriptive RootCare for Growing Healthy Trees and Shrubs in an Urban Environment
Rainbow Treecare utilizes prescriptive nutrient programs based on soil tests to
enhance tree and shrub growth, vigor and environmental stress resistance. By
understanding that a “one size fits all” fertilization program is not in the best
interests of plant health, we reduce the potential problems associated with the
over and under application of fertilizer. Rainbow Treecare utilizes soil and plant
information to manage the health of individual trees based upon actual
nutritional needs.
Our Rootcare processes are the best in the business - thorough and effective. First we analyze your plants and yard so we can prescribe the treatment best suited to your trees and yard environment. This is followed by treatment using the highest quality materials available. We use high pressure to infuse the materials extensively throughout the root zone, and we space the injection holes to allow even coverage within the rooting area under the canopy of the tree.
Rootcare Injection Pattern:
Injection probes are inserted 6 to 8 inches into the soil, and spaced approximately 2-1/2 feet on center throughout the absorbing root zone. In some soils the materials may come to the surface causing increased grass growth and/or color at the injection sites.
At Rainbow Treecare we use only slow release nutrients to ensure long-term health benefits. This also reduces the potential for run-off and leaching. Each of our products are designed to integrate readily with natures own processes.
Nutrition Programs
Urban soils vary widely in their ability to support tree nutritional needs. Some landscapes in established neighborhoods have more than ample amounts of macro and micro nutrients to sustain tree health and growth while others in newer developments may contain little, if any available nutrients. Using soil tests and over 30 years of University research Rainbow Treecare determines the nutrient needs of trees to enhance their vigor and beauty in any soil environment.

| The Rainbow Booster Program is designed for trees in environments with little to no organic matter and low levels of native nutrients in the soil. | The Rainbow Pro-Growth Program is formulated for trees in new or disturbed soils where nutrients exist in the soil, but are tied up with clay or organic particles, making it difficult for the tree to utilize them. | The Rainbow Maintenance Program is used primarily in established and native landscapes where nitrogen is available, but other nutrient deficiencies have been determined through soil analysis. |
Mycorrhizal Inoculants
Mycorrhizae may be used to enhance the absorptive capacity of roots in situations where soils have been stripped of organic matter and top soil. Mycorrhizae are fungi that form cooperative relationships with the roots of certain kinds of trees. These fungi can greatly expand the volume of the rooting network of the tree for nutrient acquisition. Rainbow Treecare is actively researching the impact that mycorrhizal organisms have on root development, nutrient acquisition, photosynthesis and vigor of commonly planted trees in the Twin Cities.
An integrated approach
When caring for urban trees it is important to make a complete evaluation of all environmental conditions to accurately diagnose all stress factors and prescribe care based on specific circumstances. This prescriptive care will help your tree meet its full potential.
