Don Davis from Ontario passed along this great information – especially click on the video embedded in the article. Ilse shows how to collect milkweed seeds and how to plant them:
Excellent article and video with Ilse Gebhard from a year ago, illustrating how easy it is to plant a suitable area with milkweed seed. I am sure that others may have useful suggestions at this important time of the year, when milkweed pods are beginning to ripen and release their seeds.
