Keep Your Leaves & Lawn Clippings out of the Streets and Gutters
Leaves and lawn clippings are a major source of phosphorus. When they are swept or washed into the nearest street or storm sewer, they end up in your local lake or stream. Keeping your leaves and lawn clippings out of the streets and gutters will have significant benefits for your local lake or stream.
Apply Only the Amount of Fertilizer Your Lawn Needs
A soil test will tell you how much-if any-fertilizer your lawn needs. Excess fertilizer may harm your lawn or pollute surface water. Fertilizer applied to your streets or sidewalks will get into the nearest lake or stream. Phosphorus from fertilizers can cause algae blooms. Use only low-phosphorus or phosphorus-free fertilizers.
Control Soil Erosion Around Your House
When soil is left bare, rainwater will run quickly over it. The moving water picks up soil particles. These soil particles have phosphorus attached to them. Some soils are high in phosphorus and are another source of phosphorus in storm water runoff. The soil in storm water runoff will end up in your local lake or stream and contribute to algae growth.
