The document discusses Rootwell, a patented tree root aeration and nutrient delivery system. It highlights Rootwell's advantages like directing water, oxygen, and fertilizer to the root zone to eliminate waste. It also notes Rootwell's ability to improve soil aeration and tree health. The document provides examples of notable Rootwell installations and summaries of studies from Davey Tree Experts and Michigan State University that found Rootwell improved tree establishment and growth. It emphasizes Rootwell's ability to help trees survive in poor soils and make landscaping visions more sustainable.

1. Understanding the Root of the problem
Roots must Respire to survive

2. 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

3.  Innovating tree care since 1997
 Over one million Rootwell’s installed
o 2 Patents, 2 Patent Pending
 Targeted tree root solutions
o Mitigating Poor Soils
o Compacted soils and clay soils
o Oxygen and nutrient deprived soils
 Sustained measured results
o Davey Tree Study, Michigan State University Study, Anecdotal
evidence over 11 years of data

4. Notable Rootwell Installations
• Disneyland ~ Orlando, Florida
• Kew Gardens ~ London, England
• Tiger Woods Golf Course ~ Al Ruwaya, Dubai
• Olympic Village ~ Beijing, China
• The Mall ~ Washington D.C.
• 9/11 Memorial ~ New York City, New York
• National Institute of Health ~ Bethesda, MD
• San Diego Zoo ~ San Diego, California

5. In 1998 Rootwell partnered with Rainbird to add a full root
irrigation product for trees and shrubs - RWS

6. 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.”

7. 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.

8. Making your vision sustainable

9. Trees are key focal points

10. Replacement of trees is expensive and does
not enhance your vision.
In warranty Out of Warranty

11. This is costly and preventable

12. And destroys the appeal

13. 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

14. Water Is Not Enough

15. Active Air Convection
Heavier Cooling Oxygen
sinks displacing warmer
rising oxygen

16. Patented: Air convection cap
Warmer lighter oxygen
rises using air convection
Cooler heavier Oxygen
sinks down exchange tube

19. •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

20. Healthy diving root growth after 10 years for more
drought resistant trees

21. Abundant oxygen supplied by Rootwell, allows
the roots to dive, seeking new water supplies

22. MDOT tree installation fall 2008 at East I-96 & Beck Rd in Novi,
Michigan. Rootwell was installed summer 2009.

28. 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.
