Packages of unsolicited seeds are showing up in mailboxes across Michigan.
On Sept. 13, the Department of Agriculture & Rural Development issued an advisory to residents about the packages and how to handle them.
“If you receive unsolicited seeds from another country, do not open the packaging or plant the seeds,” Mike Philip, director of the state’s pesticide and plant management division, said in the advisory. “USDA testing of these packages has identified hundreds of varieties of seeds, ranging from noxious weeds, to cannabis, to a wide array of vegetable and flower seeds.”
