Horticulture Programs

The MSU Extension Consumer Horticulture team provides Michigan residents with research-based information to properly manage their home environment (lawns, gardens, landscapes and ornamentals). The Macomb County MSU Extension office assists county residents with utilizing Extension resources to better diagnose plant diseases, insect & weed identification, fertilizer recommendations, pest problems, landscape questions, seeding & lawn maintenance, and more! Read on to find out about all of the resources available.

Diagnostic lab

Macomb County's Plant and Insect diagnostic lab offers a fee-based service for identifying insects or diagnosing plant health concerns. There is a $6 charge / sample. Diagnoses that do not require a microscope or are immediately identifiable are free of charge. 

As of May 2020, the MSU-Macomb diagnostic lab is currently closed. All questions should be submitted through Ask an Expert. Once the office reopens, please call before bringing any plant or insect materials for a diagnosis or identification. Gardening questions can also be asked by telephone on the statewide lawn and garden hotline (888-678-3464), which is currently accepting calls on Mondays, Wednesdays, and Fridays from 9 - Noon.

Gardening Resources

The Consumer Horticulture team's Gardening in Michigan website maintains excellent information on growing vegetables and fruits, lawn care, pollinator attraction, soils, and other content.
