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 applied the winter step a week ago. Also want you to know that my lawn has looked fantastic all season long and has never looked better. With your help and products I can say without reservation that my lawn is the envy of my neighbors and friends. Thanks for all of your help.
I have the best looking lawn in the neighborhood, three years running.
