How to have a healthy lawn without fertilizer, and keep nutrients out of our lakes and rivers  Much of the fertilizer we put on our lawns ends up in our local lakes and rivers during a rain storm or from watering the lawn. If you live in town, nutrient-rich runoff flows through a series of stormwater drains and ditches, eventually emptying into your local lake or river. The runoff flows directly into the water if you have a shoreline property.
In Scugog and the Kawarthas, this is contributing to the excessive growth of aquatic plants. It takes only 1 kilogram of fertilizer to promote the growth of 500 kilograms of aquatic plants! Here are some ways to keep your lawn healthy without using fertilizer this spring: 1. Thatching - Remove dead grass from your lawn. Thatching is a great way to help aerate your lawn and can easily be done using a standard leaf rake. 2. Aeration - Aerating every couple of years is a great way to loosen soil to allow for more water and nutrients to enter the earth. This involves the use of an aerator that removes small plugs of earth from the topsoil layer. 3. Apply compost to your lawn - A thin layer of compost (or a top-dresser containing compost) will contribute to a healthy lawn by nourishing the grass and increasing the organic matter in your soil. Be sure to prevent any compost from getting into the storm drain by keeping it off of the road, driveway and sidewalk, or from washing into the ditch. Compost can also add nutrients to water. 4. Over seeding - Over seeding will help create a thick and lush lawn and will also help choke out weeds. The thicker the grass, the less chance the weeds have to survive. Over seeding can also be done mid to late August. Have your soil tested for nutrients if you feel that you must fertilize your lawn. You can get a soil test for less than $30, and it will determine how much, and if, fertilizer is required. Contact Shalin Abbott by email or call 705.328.2271 ext. 223 for more information. If you decide to use fertilizer, be sure to apply it accurately. Fertilizer particles on roads, sidewalks and driveways end up in the lake through the storm sewers. Along a shoreline, keep fertilizer particles out of the water. Grass clippings also contain nutrients and should be kept out of the water and off the road, sidewalk and driveway.
