We love our volunteers! Volunteering at PHS is a great way to make a difference and create a positive change in the community. Every year, thousands of volunteers come together and share their love for horticulture through volunteering at PHS events. No previous experience is necessary – we give you the training you need. The only thing you need is your enthusiasm and love for all things gardening. Everyone makes a difference.
