Great product

Very responsive customer service. One week after treatment of my “cement” clay soil with ********* I was able to crumble soil in my hand, and actually pull out weeds by their roots. I couldn’t do that before! Looking forward to completing the cycle of soil enhancers and seeing the final results soon.

My Clay Soil Problem Solver

Just bought Clay Snd Hard Soil Kit and followed the application accordingly. Waiting for the results hopefully in a couple of weeks. Transaction was easy and shipping was super fast.

Amazing beautiful green garden

This soil system is amazing. I tilled this area and added my own compost. This is the 1st year growth for this bed. I followed the directions for all the products and have amazing results. I also use your rose and soil defender weekly. I am located in Landers Ca which is the high desert and we are in 110 degree weather when I snapped the shots.
