Pests’ attraction to plants is closely related to soil composition and root health. When we fertilize, we alter the delicate nutrient balance in our soils; this in turn hinders plants’ ability to defend themselves from pests. Fertilizers deplete oxygen, making it difficult for healthy, aerobic microorganisms to thrive. This weakens the soil’s food web, and plants are left vulnerable to predators. Microorganisms in the soil are unable to produce the chemicals required to fend off harmful insects. By refraining from fertilizing, we can simultaneously reduce the need for insecticides which are harmful to our health and the environment. 

Pledge to not use fertilizers on established lawns.
