What is Smart Gardening?

Smart Gardening is an initiative from Michigan State University Extension that helps people become great gardeners who are environmentally savvy and SMART! It is a campaign to help new and experienced gardeners adopt and implement real-life techniques in their yard and garden that will help them save time, money and the environment! IPM or Integrated Pest Management has long been a hallmark of MSU Extension programs but often times gardeners cannot unravel the amount of information that comes their way—-from educational institutions, magazines and commercial product producers. “Smart” helps people adopt proven, university-researched tactics in their own backyards.


Smart Gardening messages and concepts are based upon these themes: Smart Plants, Smart Lawns, Smart Soils, Smart Vegetables and Smart Pollinators.

A first look into the “Smart Gardening” initiative begins at the Gardening in Michigan website where short videos, tip sheets, a toll-free hotline and the Ask-an-Expert widget can be found.
