National Plant Health Week

09 May – 15 May 2022, including International Day of Plant Health on 12 May 2022

Text provided by Defra

Born out of the International Year of Plant Health 2020, National Plant Health Week is a designated week of action to raise public awareness and engagement on how to keep our plants healthy.

Although National Plant Health Week is led by Defra, it is a collaborative effort from over 20 organisations, including the Royal Horticulture Society and Horticulture Trade Association. By working together, we can reach a larger audience and communicate vital message surrounding plant health.

The week focuses on a key theme each day, to address important topics that will benefit plants and encourage society to enjoy and protect the plants around them using the hashtag #planthealthweek

The United Nations have this year newly designated Thursday 12th May, as the International Day of Plant Health (IDPH) to raise global awareness on how protecting plant health can help end hunger, reduce poverty, protect biodiversity and the environment, and boost economic development. The Day is a key legacy of the International Year of Plant Health 2020. For more information about the day please see International Day of Plant Health, 12 May (

What can you do for plant health?

Call to action- We are all custodians of our plants, and you can play your part in keeping our plants healthy by:

  • NUTURING the plants you have in your homes, and gardens.
  • BOOST YOUR WELLBEING- Get out and about to your local woods, parks, and gardens to enjoy your green spaces.
  • BUYING REPSONSIBLY – source plants from reputable nurseries and suppliers.
