WF Cyclists Hosting Seed Bombing Fun Ride March 20th There's a bicycling event coming to Wichita Falls that sounds ... intriguing. Here's the plan. Participants on the Seed Bombing event will arrive at the Downtown Wichita Falls Farmers Market by 10:00 a.m. on March 20th. Once you're there you'll be instructed on how to build a seed bomb. Then everyone will hop onto their bikes, go for a ride, and drop their bombs in the appropriate places. What is a seed bomb? I'm glad you asked. According to The Ecologist a seed bomb is a little ball made up of clay, compost, and wildflower seeds. The combination is rolled up into small balls about the size of a walnut or pecan that can easily be tossed into hard to access areas or in this case, easily tossed from a moving bicycle. They are not explosive in any way other than the explosion of color from the wildflowers that grow after the seeds have done their thing.
