Fall is time to collect milkweed seeds for next spring. Use only seed native to your area and pick only dry brown pods. Pods must be dry to ensure seeds are mature. Plant the milkweed in the fall in a sunny location by sprinkling seeds over loosened soil. Pat them down, add a thin layer of top dressing and water well. In the spring the plants should appear. Monarch caterpillars will be along to munch on the leaves several times through the summer. A variety of flowers throughout the summer will keep the monarch butterflies nearby.
