The RHS Advisory Service can help you grow plants, solve gardening problems, identify plants and much more.
A team of RHS Advisors write on a wide range of gardening topics for the online advice search and for the RHS Advice pages in The Garden magazine. You will also find RHS Advisors at many of the gardening shows around the country throughout the year.
If you are a RHS member you also have the great benefit of being able to contact the RHS Advisory Service for personal advice on any gardening matter.
Advice service for RHS members
RHS members can contact the RHS Advisory Service in the following ways:
Email
Email your enquiry to gardeningadvice@rhs.org.uk. Please always include your membership number. Our typical response time is three to ten days, however some enquiries that need research and analysis do take longer. You can include digital images (up to a maximum file size of 250KB)
Post
Send enquiries and samples to: Advisory Services, RHS Garden Wisley, Woking, Surrey GU23 6QB.
In person
Visit the Members’ Advisory Centre in the Plant Centre at RHS Garden Wisley. Open every day, 11am-3.30pm (including Bank Holidays).
Telephone
Call 0845 260 8000. Lines are open Monday - Friday, 10am-4pm. Please note lines can be very busy.
What information we need
Please state your membership number with all enquiries.
For an accurate diagnosis, explain how the plant was cultivated and when and how a problem developed. Send a selection of roots up to 1cm (0.5in) wide, shoot and soil samples where disease is suspected.
We endeavour to reply in five to 14 days. However, some plant identifications and laboratory tests can take more than three weeks.
PLEASE NOTE: Testing for plant viruses is not available due to the specialised nature of the diagnosis. This service is available to gardeners from the Plant Clinic at FERA (The Food and Environmental Research Agency).
