A team of two founder members - Jamie and Suzie Single - set up the Caledonian Tree Company in 1990, when we moved to Edinburgh from Australia.

After qualifying at Ryde School of Horticulture in Sydney and training at Kew Gardens in London, Jamie first came across the Australian root control system in 1986. At the time he was a landscape designer trying to source quality plant material. He was impressed by what he saw, became very interested in the theory behind root manipulation and enhancement and was hooked.

We believe that quality matters and that it shouldn't cost. From the outset, the company's mission has been to develop products that improve plant quality and to work with growers to introduce systems that deliver quality practically and competitively. Product development in conjunction with growers is one of the most satisfying areas of the business and is an on-going process.

Manufacture of both the Superoots Air-Pot and Fielder is in Scotland, near Edinburgh. The company has a factory in one of the former warehouses of the Lady Victoria Colliery, which ceased its operations in the 1980's. Fortunately, there is enough space to expand as the business continues to grow within the UK, Europe and particularly in the USA.

Protection of the environment is a driving force behind our product development. The Air-Pot wall is made of 100% recycled HDPE and can be re-used. Our new biodegradable delivery system will be an extension of this, which will enable Air-Pot and Fielder grown trees and shrubs to leave the nursery with no waste products.
