Many professional landscapers don't like weed and feed products because they waste money by using chemicals where they aren't needed. Weed and feed may harm streams and lakes. Quick-release fertilizers, commonly used in most weed and feed products, apply a quick and heavy dose of nutrients to the lawn, and are more likely to wash off into local lakes. This increases algae growth in lakes and reduces oxygen levels, killing fish and other organisms. Pesticides may not be so great for you and your kids.
Children are at high risk from pesticide exposure.
They are more likely to be exposed, and they are especially sensitive to toxic chemicals. Some medical studies have found an increased risk of cancer and other health problems from the use of yard and garden pesticides. In a science journal review of 98 health studies related to the use of herbicides and other pesticides, half the studies found an increased cancer risk. Pesticides and quick-release fertilizers may damage your lawn. Healthy lawns grow on healthy soil.
