"For the last ten years Butler Tree Farm has used “starter Kits” from Total Quality Liners (TQL) to produce quality products.  As a grower, I recommend TQL for the following reasons:

• Air Pot products have superior roots.  The trees establish much quicker thus enhancing crop rotation which equals more profit.
• Root manipulation means roots are established in a 360° degree radius.  Air pruning has eliminated a one-sided root – ball.  This keeps the starter tree vertical and is less likely to develop a crooked trunk.
• The Air Pot increases the number of root tips which enhances the uptake of nutrients and water, resulting in faster plant growth."

Joel F. Butler, Butler Tree Farm

"The Air-Pot meets the exact needs of the tree by stimulating a vigorous, healthy and natural root system for stress free and rapid establishment from the day it is planted. Who could ask for more? "
Nick Dunn, Managing Director of Frank P Matthews Ltd..

"The speed in which the plant fills the Superoots Air-Pots with root is astonishing, and all the species tried so far - even the most difficult species like Juglans and Ginkgo - thrive in it."
Nick Bentley, Arboriculturist/Tree Grower, London, May 2002

" I first saw Air-Pots being used in big numbers at Cherrylake Tree Farms in Florida, where we also looked at pot-in-pot, the accelerator pot and rigid containers. There is no doubt that the Air-Pot produces the most fibrous root system for successful transplanting, even with coarse rooted subjects such as Crataegus."
Paul Masters, former production director, Notcutts Nurseries Ltd

"The innovation of the Superoots Fielder is one that appears very promising for the users of large woody plants. The root systems of trees grown in Superoots Fielders consist of stocky lateral roots that terminate in a rounded knob. These swellings are highly meristematic and new root growth post-transplanting can be quite dramatic."
Dr James Hitchmough, Urban Landscape Management 1994.

"I hope I never have to rootball again. Lifting trees in Superoots Fielders is easy and the tree suffers no shock. We can service customers much more efficiently, meeting orders quickly, and failures after transplant are almost non-existent. There is no comparison."
Clinton Barratt, Tree Production Manager, James Coles & Sons.

"In the last few years good nurseries have overcome virtually all the technical difficulties of containerizing large nursery stock except the form and quality of the root systems produced within the containers. Superoots Air-Pots appear to solve this problem both at transplanting and in long term. These benefits should prove extremely attractive to informed customers."
Peter Thoday, Principal of Thoday Associates, Landscape Consultants.

"For out of season planting, all the semi-mature trees I have used for recent projects, including Milton Park, in Oxfordshire and Greenside in Edinburgh have been Air-Pot trees and the quality of the root systems has been superb. I have also been very pleased with the simplicity of the system and the cost, and look forward to specifying smaller trees and shrubs of similar quality in Air-Pots for upcoming projects."
Mike Smith, Macgregor Smith, Landscape Architects

"The white easylift bag and black pot have their pros and cons: the handles on the white bag make it easy to carry, but the rooting around is very slow; the compost in the black pot warms up quickly in spring, giving good early root growth, but there is the inevitable root circling.
However, there are no such problems with the Air-Pot. It produces a superb root system for transplanting. The continual pruning the roots receive in the airpot produces a mass of fibre with all the root tips facing outwards ready to burst into their new planting medium."
Martin Hillier, Hillier Nurseries

"In the past, the quality of stock we demand was only available rootballed, which precluded any summer planting. Now with the Air-Pot, we can have the flexibility of container stock and even better quality."
Graham Larby, Managing Director, Willerby Landscapes

You asked me about how our trees is doing during the wintertime here. Here comes an little story:

We are not doing anything to protect the trees during the winter, we have noticed during the years we have had this system that they manage very good without any harm at all!

The only trees I know have had their root damaged because of the cold winter is Malus in sorts, but they can have problems even if they are standing in the normal ground.

Last winter didn’t we have much snow at all (which is a good insulator) and we had a period of 10 days with low temperatures, down to about 15-20 minus celsius degrees. I must say that I was a bit worried at that time about some of the trees, especially the 50 pcs of Gleditzia triacanthos Sunburst 14-16, which is normally a very unhardy tree to be grown here. But they have been in very good shape during the summer and we delivered them to our customer last autumn without any problems.

If these trees had been grown in normal pots I am sure that they hadn’t survived. It is a big difference between an air-pot and a normal pot. It is of course the very much better rooting in the whole rootball, which is one of the answer, the air-pruning prevent the normally big amount of healthy root to be gathered around the root ball between the wall of the pot and the rootball (pot-grown trees) which easily can be damaged by frost. In the "air-pot" are the healthy roots spread all over in the whole ball, it makes the whole rootball very firm and full of roots, which seems to protect against low temperatures. This is the census of the air-pots, you get a very fast rooting in the whole rootball which also give you very good growing result at the tree during the 1st growing-season! It is normal at least that the trees grow on with one size , some even two!

This is of course no news to you, but I just wanted to tell you abut how we are getting on with the system. I hope my writing in English isn’t to bad so it is possible for you to understand my thoughts.
