Growing Instructions: Start Tropical Milkweed seeds outdoors in the spring after the danger of nighttime freezing has past. Pick a location with full sun and prepare soil for good drainage, if needed. Plant seeds 1/8" deep and 18” apart, using 3 seeds per hole. Keep the soil evenly moist until the seeds germinate in 10 - 20 days. Once the seedlings reach 1", thin out so you have individual plants spaced 18” apart. Water regularly allowing the soil to go nearly dry between each watering. Fertilize monthly in the summer with a general purpose fertilizer. To get a head start, seeds can be planted indoors in the late winter. Transplant outdoors after the danger of nighttime freezing has past.
