Having recently bought a house in Florida with an HOA the lawn is cared for by a professional company. The other day I noticed blue pellets / fertilizer on my lawn and called the lawn company immediately to find out what it was. He said its ammonium sulfate fertilizer which is safe for dogs. He has dogs and has been using it or years.
I'm still researching how safe it is. My boys haven't been and wont be spending much time outside until I conclude it is safe. |
