Master Gardener Program

The Master Gardener Program trains garden enthusiasts to learn, grow, and teach others about plants and gardening in the home landscape. Participants receive 40 hours of training via webcasting, face-to-face, and hands-on workshops, while interacting with others of similar interests. After completing their training, Master Gardener Interns volunteer 40 hours of service in county approved projects related to gardening education to become active Master Gardeners. To maintain active status, Master Gardeners must attend at least 10 hours of county approved continuing education and volunteer at least 20 hours of service on county approved projects.

Cleaning up Garden Tools

Do you clean your garden tools after a long gardening season? If you don't here are some tips! If you do, maybe still check this out to see if you are doing it correctly!


Fall "Chores" in the Vegetable Garden

"As you enjoy the fruits (and veggies) of your labor after your summer harvest, keep in mind that there are still plenty of chores to be done this fall to get ready for next year’s vegetable garden. This week's Yard and Garden entry offers tips from Ajay Nair, associate professor in horticulture and extension vegetable production specialist with Iowa State University Extension and Outreach."


Fall Garden Tasks in the Perennial Garden

"It is not necessary to clear-cut the perennial garden after the first freeze of the season. Leaving the leaves, stems, dried flowers, and seed heads of many perennials provides more interest through the winter months. Leaving the plant materials also provides an extra layer of protection for the crown and root system of the perennial. Plus, the dead stems and leaves collect fallen leaves, adding even more protection. Leaving the plant material in place and removing it in early spring instead of fall also helps provide food and protection to native pollinators, beneficial insects, and wildlife, such as birds."
