Green never looked so good
I have enjoyed the easy hose hookup and application of the product! I'm only on the second part of application plan but can already tell a difference on my lawn, my grass is much softer and greener, can't wait to complete the plan and see how it turns out on the spring especially with hard Midwest winters.
