Greg Osbourne, Horticulturist at Missouri Botanical Garden, made his first and last application of Nature Safe 10-2-8 because he thought the smell was objectionable. I explained that any smell he detected was coming from components that were very similar to dog foods. Greg owns a dog and feeds it Iams dog food. I asked him if he thought that product was smelly. He didn’t think so. We did a side-by-side comparison of the two products and there was very little difference in odor. Greg is now using Nature Safe on a regular basis.
