KCD and King County Wastewater Treatment Division hosted 27 volunteers from Expedia for a work party at City Soil Farm in Renton on Friday, September 6, 2019. Volunteers learned about this unique mixed fruit and vegetable production farm that utilizes reclaimed water and Loop® Biosolids from the wastewater treatment facilities. The garden includes UW experimental plots as well as several demonstrations of ecologically minded gardening techniques. The group split into four teams that tackled weed management in garden beds, the orchard and the rain garden. The group got the farm out ahead of much of the blackberry, thistle, and other pernicious invasive species that were encroaching from the edges of the property. Volunteers spread out cardboard and burlap and mulched on top with bark chips to deter future weeds and prepare the sites for native shrub and wildflower plantings. The volunteers worked hard throughout the day and excitedly took home some produce, as well as lots of mint.
