Great stuff!

It's a very fine powder, but I put this for minerals and Pre-Plant Plus in my garden every year and have great success.

A bit difficult to distribute.

The dust is so fine that it is very difficult to distribute it evenly using a spreader. Have to wait and see if it is as effective as I've read. Hope so.

Great value!

I ordered glacial rock dust as an amendment for my garden, as I have read great reviews about adding minerals back to the soil to increase plant vigor and health. The product shipped at a reasonable price, no tears or rips in the packaging. Can't wait to test it out in my garden!

Love the product and the company. The delivery was to the wrong address, most inconvenient

Love the product and the company. The delivery was to the same house number on a street several blocks away. Good thing that neighbor enjoyed the challenge of walking 50 pounds to the correct address. Thank the universe for the kindness of others.
