It's that time of year when we start working on our garden beds and lawns. One common gardening chore is fertilizing. Did you know that fertilization of residential landscapes is one of the leading causes of nonpoint source pollution (pollution that comes from many, scattered sources rather than one pipe or source)? When working in your landscape, please consider the environment and use fertilzers sparingly, if at all. The Leon County Extension Office is a great source for information regarding proper fertilization.
