How to Propagate a Blanket Flower
- 1). Plant directly into the fall garden bed to propagate from seed. In warm climates, the young plants will bloom the following spring. In colder climates, they will bloom during their second spring. Space seeds 14 to 16 inches apart, or broadcast them and thin out once the seedlings are 2 inches high.
- 2). Plant seeds, alternatively, in the spring and cover with about 1/8 inch of good potting soil.
- 3). Propagate seeds indoors in the early spring, if you like. Place seeds in small pots or flats, filled with new potting soil. Keep seeds in a sunny location or under a grow light, keeping them 55 to 64 degrees Fahrenheit.
- 4). Divide up the root ball of mature blanket flowers that are perennials, as an alternative way to create new plants. In the early fall, cut the plant in two with a spade, dig up both halves, and plant separately in the soil. Water in well.
- 5). Divide perennial blanket flowers every two or three years, to keep their growth strong.
