These weekly yoga classes add a spiritual dimension to weeding in the various gardens around Veblen House, as Gemma's voice wafts over the grounds, reciting a progression of positions for participants to take. The energy of the yoga sessions is very positive, and in a way, the weeding of a garden seeks to direct nature's energy towards more positive ends. Pulling the weedy plants like stiltgrass acquires more meaning if there are desired plants like boneset, Hibiscus and buttonbush that get liberated in the process and are given a better chance to grow.

Gemma's classes are "donation-based", meaning they are free, with all donations generously going to benefit the Friends of Herrontown Woods.
