Yard care and water savings tips
• Check for toilet leaks by adding food coloring to the tank. If the toilet is leaking, color will appear in the bowl within 15 minutes. Make sure to flush as soon as the test is done, since food coloring can stain the tank.
• Overusing chemical pesticides and fertilizers can damage beneficial soil life, leading to soil compaction and unhealthy plants. Chemicals can also wash off into ground water, rivers, lakes and marine waters, where they can harm people and wildlife.
Most trees and shrubs can get all the nutrients they need from the soil, and mulching once a year. But annual plants, vegetable gardens and lawns sometimes need extra nutrients. When shopping for fertilizers look for the words “natural organic” or “slow release” on the bag. Unlike “quick release” fertilizers, natural organic fertilizers won’t wash off into streams so easily, and they feed your plants slowly to keep them looking good longer.
