Very effective

I have been using John and Bob's in the garden for a couple of years with success. It has definitely improved my Midwestern soil. The optimize plus has done the same for the house plants, even revitalizing the soul of plAnts that were due for reporting. Good stuff. Plants always enter a growth cycle after application.

Great product

We are going into our second year using these products and are excited to see the changes this year in the condition of the lawn and other plants. Nice to know we are more organic in our yard after years of commercial harsh treatments that deplete the soil not build it. Keep up the good work.
