What are the restrictions on fertilizer application during the winter months in Maryland?

The restriction on fertilizer application during the winter months in Maryland is that fertilizer applications are generally prohibited during the winter freeze-thaw cycle. This is primarily due to environmental concerns, as applying fertilizer during this period can lead to increased runoff and nutrient leaching. When the ground is frozen or in thaw-freeze cycles, any applied fertilizers can wash away into nearby waterways rather than being absorbed by the soil. This not only reduces the efficacy of the fertilizer but also poses a risk of water pollution, particularly affecting the health of local aquatic ecosystems. Therefore, these regulations are designed to minimize environmental impacts and promote responsible nutrient management in Maryland.
