Where in Iowa can you find 900,000 African Night Crawlers? At the Wyatt Family Farm, Central Iowa Organic Fertilizer (CIOF). Here you will learn how worms are hatched, fed, grown into full sized night crawlers and how the organic worm castings are extracted, bagged and readied for delivery. CIOF harvests about a ton of castings every three days. Worm castings are very popular with Master Gardeners, Organic Farmers and especially with novice gardeners! Because CIOF is organic, there is no smell. Make sure you come and see the worms! New this year “Winston” the puppy! 515-961-0357 Mike and Traci Wyatt, and son Colin.
