Boxers or Briefs? As Long as They’re Cotton, They’ll Dish the Dirt on Soil

How does your garden grow? Find out by planting a pair of underwear! To educate the public about soil health, the Pennsylvania Soil Health Coalition and other soil health experts have teamed up with clothing brand The Big Favorite to launch Soil Your Undies, a campaign that challenges people to get to know their backyard microbes by planting their undies. 

Anyone with a farm field, backyard garden, or lawn can join in the fun. All it takes is a pair of 100% cotton underpants. Once they’re planted, the microbes in the soil will get to work. After 60 days, panty planters dig up their undies to reveal the level of decomposition. The more the underwear decomposes, the healthier the soils are! All who take the challenge will receive tips on how to improve soil quality.

“As we improve our soils, it changes the way that water flows across the land,” says Lisa Blazure, soil health coordinator at Stroud Water Research Center and coordinator of the Pennsylvania Soil Health Coalition. “Healthy soils soak in more water — allowing plants to thrive, adding to the groundwater, and keeping local streams flowing with clean, cool water.”

Other partners include Lancaster Water Week, the Natural Resources Conservation Service, All Together Now PA, the Chesapeake Bay Foundation, and Pasa Sustainable Agriculture.

The campaign, which kicked off in the lead-up to Lancaster Water Week, has been covered by NPR, Philadelphia Magazine, and PennLive.com.
