    Love this product! I first found it at an Amish Nursery where all of the plants looked phenomenal! If you've ever seem Amish quality flowers and vegetables, you know they are TOP NOTCH! And they told us this is the only fertilizer they use! I personally noticed results in less than 7 days! Definitely recommend!
