  • Thursday, March 7: Composting in the Vegetable Garden 
    Composting is a great way to dispose of leftover crop material and turn it into valuable organic matter that you can use later to improve the structure, water-holding capacity and nutrient content of your soil. Basic composting theory, troubleshooting and several methods of composting will be covered.
  • Thursday, March 14: Cover Crops for the Vegetable Garden
    Cover crops bring extra nutrients to the soil and help control weeds. Some also attract pollinators, which can help increase your crop yield. Organic and Small Farmer Outreach Specialist Claire Strader will talk about different types of cover crops to use in different situations, as well as when to plant and remove them.
  • Thursday, March 21: Seed Saving, Harvesting and Storage
    Learn how to successfully harvest and store seeds from a variety of crops. Success is more likely with some crops, and less likely with others.
