Introduction to Microgreens

Posted on by | 1 Reply

This material was presented at the Oregon Master Gardener Association’s 2016 Mini-College.  

Microgreens are easy and fun to grow. They are great for garnishing sandwiches and salads.  Microgreens can be also be used in classroom settings to teach botany (and grow a snack!).   In this presentation, I covered:

  • The difference between sprouts, microgreens and baby greens
  • The uses for microgreens
  • How to grow in soil and hydroponically (Handout from class)
  • Troubleshooting common problems

During the talk, I refer to a published paper that discussed the health profiles of different microgreens.  You can view the entire paper here.  Keep in mind that the amount of total amount of published research on microgreens is small.  Most research has focused on growing & handling methods to avoid food borne illness or extend shelf-life.

When purchasing seeds, it is most economical to purchase in bulk.  You can find seeds locally at garden centers or online retailers.  Johnny Seeds is one possible resource.  They have a great catalog with color photos that compares growing characteristics and flavor descriptions.

Here is a shortened version of my presentation (complete slide set):

Is there a list of ash tree alternatives? Choose anything but ash (Fraxinus sp.) to avoid loss to Emerald Ash Borers.  Good general source of information: http://www.emeraldashborer.info  Local training from OSU Extension on potential invasive insects affecting trees: http://pestdetector.forestry.oregonstate.edu/programs/registration-and-online-course

What to spray to treat Azalea Lace Bug? http://insect.pnwhandbooks.org/hort/landscape/hosts-and-pests/azalea-rhododendron-azalea-and-rhododendron-lace-bug Robin Rosetta with the OSU Extension Nursery IPM program has indicated that the nymphs are emerging.  This stage in the life cycle is especially vulnerable to contact insecticides (this is different from the systemic insecticide that the questioner mentioned).  Labeled insecticidal soaps and neem-based products may be a good choice.  Good coverage of the underside of leaves will be necessary.

Recent change in USDA Hardiness zones-does that indicate global warming? “Climate changes are usually based on trends in overall average temperatures recorded over 50-100 years. Because the USDA PHZM represents 30-year averages of what are essentially extreme weather events (the coldest temperature of the year), changes in zones are not reliable evidence of whether there has been global warming.”  From: http://planthardiness.ars.usda.gov/PHZMWeb/AboutWhatsNew.aspx
