Best fertilizer I have used.
I recently moved into a townhouse community and my lawn was very thin and full of weeds. I wanted to go an organic route, and learned about Natural Alternative lawn and garden products through your website. After overseeding my townhouse lawn this past fall, and once again in the spring, and fertilizing using your 15-0-4 Small Lawn Fertilizer each time, my lawn is now healthy, and thick, with great color.
After using your fertilizer and with irrigation the lawn is healthier and maintaining it is much easier.
