Golden Goddess Propagation: Multiply Your Bidens Gardneri With Ease

Bidens gardneri, more charmingly known as the "fern-leaved beggartick" or simply "Bidens," is a cheerful, sun-loving annual boasting a profusion of golden daisy-like flowers. This easygoing beauty, native to Central and South America, brightens up gardens with its vibrant blooms from late spring until frost. While you can easily purchase Bidens seedlings every year, why not multiply your stock and impress your gardening friends with your propagation prowess?

Here’s a deep dive into the world of Bidens gardneri propagation – with two surprisingly simple methods:

1. Seed Starting: The Gift that Keeps on Blooming

Starting Bidens from seed is incredibly rewarding and straightforward, even for beginners. Here’s your step-by-step guide:

Timing is Key:

  • Indoors: Start seeds 6-8 weeks before your last expected frost. This gives them a head start and ensures earlier blooms.
  • Direct Sowing: Sow seeds directly into the garden after the danger of frost has passed and the soil is warm.

Sowing the Seeds:

  1. Choose a well-draining seed starting mix. Moisten the mix before filling seed trays or pots.
  2. Sprinkle seeds thinly on the surface and lightly press them down. Bidens seeds need light to germinate, so avoid burying them deep.
  3. Mist the seeds with water and cover the tray or pot with a humidity dome or plastic wrap to retain moisture.
  4. Place the tray in a warm, bright location. Avoid direct sunlight, which can be too intense for young seedlings.
  5. Keep the soil consistently moist but not waterlogged.

Transplanting Your Treasures:

  1. Once seedlings develop two sets of true leaves, they’re ready to be transplanted into individual pots or outdoors after hardening off.
  2. Harden off your seedlings gradually over a week by introducing them to outdoor conditions for a few hours each day. This helps prevent transplant shock.
  3. Choose a sunny location with well-draining soil for your Bidens.
  4. Space plants about 12-18 inches apart to allow for good air circulation and prevent overcrowding.

2. Cuttings: Cloning Your Golden Beauties

Propagating Bidens from cuttings offers a quicker way to achieve blooming plants. Follow these simple steps:

Taking the Cuttings:

  1. In the morning, when the plant is most hydrated, use a clean, sharp knife or pruning shears to take 4-6 inch cuttings from healthy, non-flowering stems.
  2. Remove the lower leaves from the cutting, leaving 2-3 pairs at the top.
  3. Dip the cut end in rooting hormone (optional but recommended) to encourage faster root development.

Encouraging Root Growth:

  1. Plant the cuttings in a pot filled with a well-draining potting mix, burying the nodes (where the leaves were removed) beneath the soil.
  2. Water thoroughly and cover the pot with a clear plastic bag or humidity dome to create a warm, humid environment.
  3. Place the cutting in a bright location, but out of direct sunlight.

  4. Keep the soil consistently moist and check for root development after 3-4 weeks by gently tugging on the cutting.

    Transplanting Your Clones:

  5. When you feel resistance (indicating root growth), your Bidens cuttings are ready to be transplanted.
  6. Acclimate them gradually to outdoor conditions before planting them in their permanent location.

Reaping the Golden Rewards:

Whether you choose seed starting or taking cuttings, propagating Bidens gardneri is a rewarding experience that fills your garden with vibrant color. Remember to provide your new plants with adequate sunlight, well-draining soil, and regular watering. With a little care and attention, you’ll be enjoying an abundance of these golden beauties for years to come!
