Program Offerings

Home Horticulture

Horticulture is an activity that is enjoyed by individuals with a variety of experience levels and garden sizes. Home gardeners can take advantage of a variety of programs. Information can also be obtained through phone calls and office visits. Samples of plant material can be brought in for diagnosis and suggestions for a solution to the problem can be offered. Home horticulture classes are often taught to groups on selected topics of interest. Individuals wishing to acquire more in-depth horticulture information are able to do so through the University's Master Gardener Program.

Teacher and Youth Related Horticulture

Horticulture and plant science topics offer an interesting avenue of instruction for teachers. Inservice education in plant and soil science related topics are offered so teachers can integrate plant and soil science into their total curriculum. Classroom topics can also be developed as one time special interest sessions for classroom groups. Youth horticulture opportunities are offered to those who want to be involved in horticulture judging and identification contests, public speaking, or demonstration contests.

Commercial Horticulture

Individuals and companies involved with horticulture on a professional and commercial basis have a variety of resources available to help them in their business. Extension provides updates for professional horticulturists through grounds maintenance clinics, professional growers meetings, and pesticide clinics. Extension also works closely with professional associations by providing expertise on programs the associations organize. Consultation services are offered to assist growers and horticulture maintenance professionals in the area of pest identification and management, culture, and plant selection.
