The Winnebago County Master Gardening Association has two ongoing fundraising programs:
Wonderful Wormiculite is a natural fertilizer consisting of worm castings that the WCMGA buys in bulk and repackages for sale at the Oshkosh Farm Market every Saturday morning, June until October, and at special events such as the Home & Garden show at the SunnyviewExpo Center in March, the annual Paine spring plant sale in May, and WCMGA continuing education sessions. Members can obtain Wonderful Wormiculite at any time at a discount. Wonderful Wormiculite can be spread dry in any garden or made into a tea for indoor and potted plants.
