I called Home Depot and spoke with the buyer in the garden dep't. and told him of my dilemma. I explained to him the importance of the milkweed plant to Monarchs and he told me he would have the supplier of these plants give me a call. I think it is suggested when you buy a new milkweed that you wash it down with water and only place one cat on it to make sure it's ok. I won't make this mistake again!
