    Exactly what it says it is.

    It seems to be relatively pure. Small amounts of discoloration but dissolves cleanly. Appears to react chemically as predicted. Perfect for stump removal. Time will tell if it's good as a fertilizer, but I don't doubt it would work.

    Recommended product for removing old tree stumps

    I have old oak tree stumps in my front yard that were from trees that were cut down several years ago. Even though the tree service did stump-grind them, they still had some visible stumps & extensive root systems that were impeding the growth of grass & evergreen hedges that I planted in place of the trees. I used the potassium nitrate to expedite the decomposition of these stumps. After just a few days, most of the old stumps are gone. This is a highly recommended product if you have old tree stumps that need removal w/o tearing up your yard having a tree service do them. The service from Seed World has been excellent. The only (minor) issue was with USPS delivery, which being that I also live in Florida took a little longer than expected (checking the tracking, for some reason my package ended up for a time in Jackson, Mississippi(!!) it may have been a mistake on USPS part as this was to be sent to Jacksonville, Florida). I would recommend Seed World to use UPS or FedEx. That being said I am quite pleased with Seed World customer-service and would happily be glad to offer repeat business! :)

    One bag was leaking

    The order came as three bags packed very well in a solid cardboard box. Somehow one broke open losing less than a quarter cup. No big deal since its all going on stumps.
