Understanding the Root of the problem

Roots must Respire to survive

The Rootwell Advantage

Direct active oxygen exchange to the critical root-zone Direct watering to the root zone eliminating wasteful run off Direct fertilization to root zone eliminating costly waste Direct visual installation inspection criteria for newly

planted trees Direct evacuation of excess water from the root-zone

Davey Tree Study; Evaluation of Rootwell® System in the Establishment

and Health of Bare Root Transplanted Trees October, 2000

“In our (Davey Tree) opinion, proper fertilization and proper improvement of soil aeration can positively

improve overall plant health and should be included as a part of the plant health care management tool.

Rootwell Systems should be a good tool to use in areas where hardscape, like concrete, exits.”

Michigan State University by Bert Craigg ; Growth and physiology of landscape trees in response to root aeration with Rootwell’s,

Objective: The objective of the current project is to determine the effect of the Rootwell root aeration system on growth and physiology of recently established landscape trees.

Trees are located at the western edge of the campus entrance off Trowbridge Road

Making your vision sustainable

Trees are key focal points

Replacement of trees is expensive and does not enhance your vision.

This is costly and preventable

And destroys the appeal

Poor soils and soil compaction can result in Water and nutrient runoff Deprivation of oxygen and nutrients forcing roots to surface Roots seeking survival develop adventitious roots and or

dysfunctional root mass Slow death Girdling roots, typically outside warranty period

• Direct Watering to the root zone• Captures potable water and rain water, above

and below the surface redirecting it to the root zone

• Efficient utilization of our water resource saves on costly over watering

• As the water in the macropores drains away a fresh supply of air enters the soil to provide oxygen for root respiration.

• Direct Fertilization to root zone

• Deep root targeted fertilization saves time and money

• Reduced fertilizer runoff to aquifer, streams, rivers and lakes helps to reduce the environmental impact

Rootwell Specifications Specifications for 3” Diameter Root Aeration and Nutrient Delivery Device for Trees

The tree root aeration and nutrient delivery device shall be manufactured specifically for this purpose. It shall be constructed of a single tubular high-density polypropylene polymer. The root aeration device shall contain sidewall openings in a horizontal and vertical pattern, equally spaced, that span the entire length and circumference in a uniform manner providing a 5:1 ratio of sidewall openings area to total surface area equally. The sidewall openings may number in the thousands depending on the length and diameter of the root aeration tube model. The root aeration device shall be capable of having the sidewall shape distorted without damage to the device. The top and bottom end caps shall be constructed of a high-density styrene polymer. The top end cap also contains the air convection insert device which shall have a flexible central tube that extends from the top cap into the tube’s interior 5”. The flexible tube shall have an outside sidewall dimension of .3125 “, and an internal diameter of .25 “. The top cap has additional ¼” openings to promote the convection of internal air currents with outside air for fresh air transition for increased Oxygen and Nitrogen content.

 The dimensions: 18”L x 3” Diameter.
