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.
I live where the soil is already high in phosphorus (the middle number) and it's hard to find any with none locally. I buy one of these each season and they are well worth the cost. My neighbors all say my yard is looking much better than under the prior homeowner.
I have the best looking lawn in the neighborhood, three years running.
