How We Tested
We sprayed a weed and feed on one half of the lawn and left the other half untouched. We compared the two halves over the next couple of weeks. Within a few weeks, we noticed that the half with the weed and feed looked fresh, green, and more attractive. The half that did not have the product started looking dull and malnourished.
