Spring Fertilizing and Lawncare and Stormwater Management

Green Grass and Clear Water

Many of us value having nice lawns and enjoy the time we spend working on them.  However, some lawn care practices can create water quality problems.  Plants need nutrients to grow, but excess nutrients, including the nitrogen and phosphorous found in fertilizers, can run off our properties when it rains and cause problems in local waterbodies.  Too many nutrients in our water can trigger algai blooms that cloud water and rob it of oxygen.

Here are some easy practices for creating and maintaining a truly healthy lawn that looks great and is safer for the environment:

• Test your soil.  Only apply fertilizer when necessary
• Apply fertilizer sparingly and ensure proper fertilizer application rates
• Apply fertillizer in the spring and early fall when grass is vigorously growing
• Select fertillizers with low or no phosphorous unless a soil test indicates otherwise
• Apply organic fertillizers if possible
• Choose slow release fertilizers near waterbodies
• Try not to apply fertilizers near waterbodies
• Don't overwater.  Typically, 1 inch of water per week applied over 1 or 2 days is enough
• Mow grass no shorter than 3" high
• Cut grass often enough so you never remove more than 1/3 of the blade at a time
• Leave the clippings after mowing so they can return nutrients to the soil

Using these water-quality friendly lawn care and fertilizer recommendations is a small change that can make a big difference.
