Pruning
Pruning is not necessary for Bidens schlechteri Sherff var. wildii Sherff. However, deadheading, the removal of spent flowers, promotes better blooming and extends the flowering period. Cut off the dead flowers just below the spent bloom, taking care not to damage the healthy plant parts.
Propagation of Bidens schlechteri var. wildii
Bidens schlechteri var. wildii, commonly known as Wild's bur marigold, is a herbaceous perennial plant that belongs to the Asteraceae family and is native to North America. Propagation is the process of reproducing plants, and there are various methods for propagating Bidens schlechteri var. wildii:
Seed Propagation
Propagation of Bidens schlechteri var. wildii via seed is a simple and straightforward process. Collect the seeds from mature flowers when the petals begin to drop. Sow the seeds in a propagation tray or pot, and cover them with a light layer of compost. Water the seeds thoroughly and place the tray in a well-lit area. Germination should occur within 14 to 28 days. Transplant the seedlings to individual pots once they have developed several true leaves and are large enough to handle. Continue to grow the seedlings in a bright area until they are strong enough to be planted outdoors.
Division
Division is a method of propagation suitable for mature Bidens schlechteri var. wildii plants. Divide the plant in spring or autumn when it is in a dormant state. Carefully lift the plant and separate the clumps using a sharp, sterile knife, ensuring that each division has roots and shoots. Replant the divisions in their new position, ensuring that the soil is moist and well-drained.
Cuttings
Cuttings are another method of propagation commonly used for Bidens schlechteri var. wildii. Take cuttings from a healthy parent plant in early spring or early autumn. Cut a 10cm shoot from the plant just below a leaf node, and remove the lower leaves on the stem. Dip the cut end in rooting hormone and place it in a pot of compost. Water the cutting well and cover it with a plastic bag to create a humid environment. Place the pot in a well-lit spot, avoiding direct sunlight. The cuttings will root in approximately 2 to 3 weeks.
By following these propagation methods, you can easily propagate Bidens schlechteri var. wildii and enjoy the beauty of this lovely plant in your garden.
