My daughter loves going to the dollar store and when she wants to go I say sure so I can get the least expensive fertilizer bag openers that work great. Lay a full bag of Fert on the edge of the hopper or even in it and Slice it open. Most efficient way with no spilling, not dusty that way and no second lifting of the bag. $2.14 and I am good for another service+. How do you open fertilizer bags?
