Fertilizers can improve the appearance and health of your lawn or garden, but they can also create health and environmental dangers. Fertilizers can pollute groundwater, endanger children and pets, disturb aquatic life and even damage your grass.
Chemical and organic fertilizers can contaminate groundwater and surface water like lakes and rivers, which can damage aquatic ecosystems and endanger human health.
Fertilizers can also be dangerous to pets and children, causing increased risk of leukemia, asthma, allergies, birth defects and decreased fertility.
Fertilizers can also disturb aquatic ecosystems. For example, nutrients can cause excessive algae growth and can kill fish.
Overuse of fertilizers can also harm your lawn or garden. Always read fertilizer directions carefully and do not use more than recommended.
If you choose to use fertilizers, don't over-water after applying fertilizer, check your soil's pH before adding fertilizer, sweep up spilled fertilizer and leave lawn clippings on the lawn after mowing.
