Satisfied
I have used this on several lawns. It's not a miracle grower, it just conditions my dirt and it does take awhile to see improvements. But they do happen. Satisfied.

It qorked
I purchased this when I found blossom rot on my container-planted tomatoes. It was easy to apply, by just spreading the granules over the top of the soil. The substance dissolves over time with watering, and seemed to be the fix for my problem. It stopped any newer tomatoes on affected plants from developing the rot, and did not spread to the other tomatoes in the garden.

Worth a try
The price was good so I bought it. I can't give 5 stars because the jury is still out. I just used it in my garden and waiting to see what happens.
