The Royal Horticultural Society Quite possibly three of the most well known letters in horticulture.
This is a really informative site with many hi-tech features to help you identify plants, pests and even open gardens in your area. Information on the major flower shows, such as Chelsea (don't forget to visit the Harrod Horticultural stand) is also included.
If you're lucky enough to live near, or have plans to visit the RHS gardens at Wisley in Surrey, you can see and touch some of our Harrod Horticultural fruit cages which have pride of place on the Fruit Field and in the Model Fruit Gardens.
