Saturday, February 20, 10:30 a.m.-12:30 p.m.

Julie Weisenhorn, Horticulture Educator, University of Minnesota Extension

After a long, cold winter it's easy to go a bit wild at the garden center, but proper plant selection is critical to sustainable landscapes and the overall success of a design. Learn proper plant selection by:

  • Understanding the site itself - its soil, light, moisture, exposure, size, etc.
  • Choosing plants that will thrive in your specific site
  • Work in Extension's Plant Elements of Design plant selection database to try out your new knowledge on your own landscape
You will leave the class with increased confidence to make plant choices in your 2020 garden, and an understanding of tools that are available to help!
Required Equipment
A wifi-ready device, such as a laptop or tablet. Smartphones will also work, but not preferred!
