Winter be damned. I'm gonna grow milkweed right thru the frost. Arizona milkweed and Aquatic milkweed are the number one stunners of the season. Tropical's persist, or die, depending on the duration of freezing weather.
Seed starting tips: put is soil and wait, put in soil cover with lid and wait, clip and water germinate, don't clip and water germinate. So there isn't one best way. Try different ways and see how the seeds start best for you. I learned that Aquatic milkweed likes to sit in soil for nearly a month before germinating. Most other milkweed seeds will germinate in one to two weeks.
Inspired by this wonderful Christmas gift from my wife I decided to try growing milkweed in a jar. I rinsed out the honey jar and added soil. Sprinkled a pinch of Milkweed Medley on the surface of the soil and watered the seeds and soil. Placed the cap w/ holes on the jar. Set it on the window sill and in a few weeks these milkweed plants are growing!
Jars are not great for milkweed because over watering and fungal disease is likely to occur without drainage holes.
The double-cup is a good way to care for seedlings. In the top cup you poke drainage holes. I poke three holes with the tip of my paring knife. Add soil to the cup with drainage holes. Add milkweed seeds. In this cup I am growing Green antelopehorn Asclepias viridis. Water the seed into the soil. Place the top cup in the bottom cup and place in a sunny window.
