Lawn and Garden

Horticulture is the science and art of growing fruits, vegetables, flowers or ornamental plants.

In Johnson County, maintaining attractive home and commercial landscapes not only increases property values but promotes an improved quality of life that makes our community a great place to live.

Whether you have a question about lawns, vegetables, flowers, or landscape maintenance, Extension information is created for use by everyone, including homeowners, lawn services and nurseries.

In Johnson County, we have two agents:

Dennis Patton is responsible for ornamentals, trees, shrubs, flowers, turf,  horticultural environmental issues. He oversees the Extension Master Gardener program.

Zac Hoppenstedt is responsible for fruit and vegetable production.
