Does burpee put chemicals on their morning glory seeds?
I'm not sure if they do or not but i can tell you that what i did was just put my seeds in a bowl of water and a little soap and washed them. Then I crushed the seeds and put that into teabags. I then soaked that in water for a few hours and then took that liquid and put it into a water bottle. I gonna trip on it this weekend but my friend who's done it before told me to do it that way so good luck to you.
