Still evaluating

I’ve been using this product for last two growing seasons. I can say that I think it might be providing improvement to the overall look of the lawn, but this year has been extremely hot, dry and regardless of how often, long I water (usually mornings before 10AM) I’ve yet to realize anything close to what I see in various photos. I’m sticking with this product line through ‘24 and decide if it’s worth the cost.


Have not tried yet but will be soon

Unfortunately, I was only able to make a small strip due to wind, storms and or both a few weeks ago; haven' t really noticed a difference on that small area. I hope the mixture is still good because it is still sitting in my sprayer; I hope to get the lawn sprayed today, 11 Apr 2023.

Easy transaction and delivery. Have one-acre irrigated property, needed way to fertilize lawn and trees regularly so that all fertilizer is absorbed between irrigation times. This was a good option. Don't with granules simply due to this working better and the birds don't take it away. So far it has worked better than expected.

Grab two!

Unfortunately my neighbors don't keep up with their lawn as much as I'd like for them to and this stuff is great at keeping my lawn green and healthy as well as keeping their weeds away. I also like to combine this with the Covington Aerator and a scoop of Brix boost powder. Go ahead and grab two!
