Calendar of Events
Explore everything from propagation, to garden talks, demonstration tours, cholla skeleton art and so much more! It's our mission to connect you to the education and experiences you need so you're ready to successfully garden in the desert.
Plant Sales
We hold plant sales every April and October at our Cooperative Extension office at 4210 N. Campbell Avenue, Tucson, AZ 85719. We’ll have a “fabulous selection of plants, cacti, and succulents, perennials, and a wide variety of water-wise plantings well suited for our Tucson area.” We will send out a plant list closer to the sale date. Cash, checks and credit/debit cards welcome.
Do you need compost, soil probes, or our Master Gardener’s Handbook? We will have that and more for sale. Master gardeners will also be on hand to answer all of your questions. Consider spending some time touring our Demonstration Gardens for inspiration.
Free Online Gardening Talks
Join our Master Gardeners online no matter where you live and get access to trusted, research-backed advice to take your garden and landscape to the next level.
Free In-Person Library Talks
Library Talks bring our Master Gardners us to locations throughout Tucson and beyond. Check out our event calendar for when we'll be at a library near you.
Demonstration Garden Tours
Explore our 12 demonstration gardens, which feature native, non-native, and drought-tolerant plants. We showcase various planting, irrigation, and composting methods for desert horticulture.
You can also register for free tours lead by Master Gardeners most Wednesdays and Saturdays starting at 9:00 am. Pay attention to the weather as we cancel the tour if it rains. Tours are available Feburary through May and September through December.
Campus Arboretum Tours
Did you know that the University of Arizona campus is a famous Arboretum? Considered one of the best campus Arboretums in the country, the 400 acres are home to outstanding trees from around the world or from our own Sonoran Desert.
Every Sunday morning from mid-September to mid-May, Master Gardeners lead free tours around the Campus Arboretum. There is a series of six tours, each one highlighting something different about this unique collection. Check out the descriptions (below) and use this link to register for any of these tours.
