To propagate Bachelor Button, the most common method is to sow seeds directly in the ground after the last frost, as they are easily grown from seed and considered one of the simplest flowers to propagate; simply scatter seeds thinly in well-drained soil, cover lightly, and keep moist until germination; you can also start seeds indoors in pots or seed trays a few weeks before the last frost for earlier blooms. 

Key points about propagating Bachelor Button:

Seed sowing: Plant seeds directly in the garden in late winter or early spring, depending on your climate, in a location with full sun. 

Soil preparation: Ensure the soil drains well and is lightly tilled before planting. 

Seed depth: Sow seeds about 1/4 inch deep and lightly cover with soil. 

Watering: Keep the soil moist until germination, then water regularly as needed. 

Thinning: Once seedlings emerge, thin them to 6-9 inches apart. 

Other propagation methods (less common):

Division: In early spring, carefully divide established Bachelor Button plants to create new plants, ensuring each division has roots and shoots. 

Cuttings: Although not as reliable, you can try taking stem cuttings in early summer, rooting them in a moist propagation mix. 

Important considerations:

Variety selection: Choose Bachelor Button varieties that suit your climate and desired color. 

Deadheading: Regularly remove spent blooms to encourage continuous flowering. 

Winter care: Bachelor Button is typically considered an annual, so it will die in cold climates.
