who we are...
Green Tree Garden Design is run by Fiona Green. A keen gardener since childhood, she trained as a garden designer at Capel Manor College, Enfield. She now holds the RHS Certificate in Horticulture, the National Open College Networks Diploma in Garden Design, and the City and Guilds Diploma in Horticulture and Hard Landscaping. Fiona is helped by Marcus, Alison F and Alison N, all of whom are experienced horticulturalists.
Using her eye for design; understanding of materials and construction techniques; and extensive knowledge of plants and horticulture, Fiona is able to deliver the widest range of design and planting solutions. Fiona is a pre-registered member of the Society of Garden Designers, and works to their professional standard.
Fiona has built up good relationships with reliable, local hard landscapers and tree surgeons so that Green Tree Garden Design can act as the primary contact for the design project.
Whatever style of garden you have, or aspire to, Green Tree Garden Design can help you to achieve it.

We were delighted to receive the prestigious awards of Best in Houzz 2015 and 2016 for Design, and Best in Houzz 2016 for Service - a great honour and testament to all the hardwork, professionalism and commitment from the entire team.

About Us
CIRCLE GARDEN SELECTED BY FRENCH HOUZZ AS THEIR FAVOURITE GARDEN PROJECT IN THE BEST IN THE WORLD TOUR OF 2017!
Welcome to our website. We are a small, friendly and professional award-winning garden design, planting and garden renovation company based in Harpenden, Hertfordshire. We design gardens in Harpenden, St. Albans, and the rest of Hertfordshire, along with Buckinghamshire and Bedfordshire.

Green Tree Garden Design is run by me, Fiona Green. Using my eye for design; understanding of materials and construction techniques; and extensive knowledge of plants and horticulture, I am able to deliver the widest range of design and planting solutions. Supported by a fabulous team of gardeners, landscapers, and tree surgeons, I act as the primary contact for the design project, from the very first telephone call to completion of the fully planted garden, and beyond.

Excellent customer relationships are key to our success, and I spend a lot of time understanding exactly what you want from your garden to ensure that the finished product fully matches your dreams. Many of our customers have become friends, and a couple have now asked me to design the garden in their new house, having moved, which is very exciting.

Whether you desire a contemporary urban garden, a traditional rural garden, or any other garden style, Green Tree Garden Design can help you to achieve it.
