    Sulfate of Potash Order

    The 50 lbs bag of Sulfate of Potash 0-0-50 arrived earlier than expected and in good shape. I look forward to applying it after the lawn dries from all of the recent rain. If I need to purchase more items in the future, I will definitely consider Seed World USA. Thanks for the prompt and efficient service and delivery.

    Sulfate of potash 0-0-50

    Bag had a hole and was about half full. Fertilizer was coming out of the box too. I think I will buy in a store next time to avoid this issue.

    Large chunks in the bag made it very difficult to spread accurately. The chunks kept clogging up the spreader.

    Received one of two bags ordered

    I ordered two bags of fertilizer, which was shipped by FEDEX. Unfortunately, one box was opened enroute and the contents removed. A call to seed world was made and they were very professional and courteous. They immediately sent me another bag without charge. Amazing customer service. I highly recommend Seed World.

    This was my first time purchasing with Seed World. Ordered a 50 lb bag for the lawn and recieved it the next day, so I was able to get it down that weekend. Very happy with the price and speedy delivery. Will do business again.
