I have sent this review so others may be aware of the level of customer support.

Great product. Inconsistant product shipment

Stumbled onto EM from learning about Bokashi composting. I decided to try BioAG. Bought one gallon from Amazon fulfilled by SCD and the expiration date is 2024. So when I saw that SCD had earthmonth discount, I ordered another gallon and was surprised the expiration is 2022. The product is guaranteed but I learned that as the expiration date approaches, it is still OK to use but the number of bacteria will be less. So I was a little disappointed at that situation. As for the product, the soil retains water much better after a couple of application. Not enough time to know the full effect. One thing, I did not read the instruction and sprayed it on my flowering pomegranate tree and some flowers dropped. Not suppose to spray on flowers. Overall, I would recommend amending the garden with BioAG.

Thank you so much for your 5-star review! We apologize for the inconvenience you experienced with your second order. We fulfill our orders based on first-in-first-out method, thus the difference in the expiration date. Nevertheless, the product is guaranteed if it’s still within its best-by date. Please let us know what we can do for you in the future.

Great for Raised Bed Gardening

This is the third year using Bio Ag on the raised beds both as a soil drench and a foliar spray, and the results have been much better than expected. As the plant health has improved from the increased microbial activity, both the quantity and quality of the harvested vegetables has improved. I mix the Bio Ag with molasses and fish emulsion to spray on the plants as well as drenching the soil every two weeks, and it has virtually eliminated insect pests and the milky spore disease. This company also provides great customer care.
