Visit an advice desk at an RHS Garden

Get help from friendly experts at advice desks (see times and locations below) across all five RHS Gardens. To make the most of your visit, bring:

  • Questions along with background information, such as how a plant has been grown
  • Photos on a phone or tablet to illustrate the issue
Please note: Plant samples should not be brought, this helps protect the gardens from pests and diseases.

Frequently asked questions about the service

Get answers to the common questions about the RHS Gardening Advice service:

What gardening questions can you help with?

The RHS Garden Advice team can help with general gardening questions, plant identification, garden wildlife, and solving plant problems. 

What can and can’t be identified?

The team can help with all ornamental plants, but there are limits to this service:

  • Identification is limited to five plants samples at a time 
  • Cultivar-level identification isn’t available 
  • Wildflowers from the countryside (i.e. outside gardens) or those photographed in overseas locations can’t be identified 
  • Seeds collected abroad that contravene quarantine restrictions or CITES can’t be identified
If your plant is dying, use the online service to send photographs and information about the plant. Many issues can be successfully identified from just photos. If you are unable to use MyRHS, please call and the advisors will work out how best to help.

For questions about other areas of the RHS, see the contact us page to find the best team to assist.

How long it will take to answer questions?

The aim is to answer all online and postal enquiries within 10 working days. The team often reply to online questions within 2–3 days. Keep an eye out for an email notification to confirm when the question has been answered, or logging into MyAdvice to check.

Use of service

RHS members can use the online service as often as needed, however, phone calls are limited to one per day to ensure fair usage for all members.
How can I send in sample?
Start by sending an online enquiry with the information and some photos of the problem on the plant. Many issues can be identified from photos. If unsure what to do, please give a call first.

Please don’t just send samples. These are often the wrong ones, making it difficult to provide the answers needed.

If samples are required for examination in the laboratory, these will be requested in the reply. Laboratory testing can take 2–3 weeks to produce results, which is why it is suggested to send photos, as it is usually as accurate and quicker.
