My missus says the guy at the supply store calls it 'Boon Cow' but hasn't a clue what it is or if it's toxic or not. Suspect it's not but with a couple of pups running around the yard, don't want to take any chances.
Spreading it throughout the garden is supposed to reduce the bacteria and keep snakes away so I suspect it's Lime Powder but not sure.
Thanks in advance for any helpful tips!
