Come take a look at the complex world of organic gardening. You will learn how to use organic gardening principles to control pests and diseases effectively, and why some pesticides are considered organic and others are not. Just because some pesticides are allowed in organic gardening does not mean that precautions are not warranted. Sometimes the best way to handle pests and diseases is by implementing good practices. Each person attending must register prior to the program.
