Growing Healthy Futures
The Lewisburg Community Garden utilizes only organic, cruelty-free methods to grow our produce. The specific harms of conventional pesticides are well-documented as being harmful to air, soil, and water quality across the globe. Some pesticides, if applied improperly or overused, can cause nerve damage, irritation, and inflammation, which can be poisonous or fatal to humans and animals alike. Research has shown that more than 95% of pesticides and insecticides reach destinations other than their target species; In order to eliminate any possible contamination, our plot renters are contractually obligated to use only approved pesticides, repellents, and pest management methods.
The following organic pesticides and repellents have been approved for use by our Garden staff:
