About Us

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.

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.

Manufacture of the Superoots Air-Pot container is in Scotland, near Edinburgh. In Autumn 2011, production has moved to a new factory in Prestonpans, East Lothian with new machinery and facilities which will permit greater flexibility in production. Charlie Johnstone manages all aspects of the manufacture and dispatch.

Recently, we expanded the team to include Massimo Della Casa, who splits his time between Pistoia, Tuscany and Normandy, France supporting our Italian & French customers and developing the business there as well as in Spain. He is now being summoned to Greece, Morocco and beyond…
