Crystal Stevens and her husband, Eric, have been managing La Vista CSA Farm for the past 6 years. As they operate on a shoestring budget, this forces them to find creative, cost-effective methods to improve soil fertility and plant health in order to boost crop yields. Upon their arrival at La Vista, they built vermicompost bins and added a mail-order bag of 250 worms which have multiplied by the hundreds of thousands since then. They have been teaching Vermiculture 101 workshops for several years, and have both completed the Missouri Master Naturalist and Missouri Master Gardener programs. Crystal is a blogger for Mother Earth News and contributes regularly to The Healthy Planet, Grit Magazine and Permaculture Magazine. She also hosts dozen of workshops on resilient living and teaches a summer gardening camp for kids.
