The cuttings should be about 4 to 6 inches long, and they should be taken from the upper part of the plant. Remove the leaves from the bottom two-thirds of the cutting, and dip the cut end in rooting hormone. Plant the cutting in a pot filled with well-draining soil mix, and water it regularly until it roots and new growth appears.
Propagation Through Division
Bidens superba Sherff var. brachycarpa Sherff can also be propagated through division, which involves separating an existing clump of the plant into smaller sections and planting them individually. This is best done in the spring or early fall. Dig up the plant carefully, and divide it into sections using a sharp, clean knife.

Disease Management
Bidens superba Sherff var. brachycarpa Sherff is prone to several diseases that can hinder its growth and development. Some of the common diseases affecting the plant include:
- Botrytis blight: This is a fungal disease that appears as gray-brown spots on the flowers and leaves. To manage this disease, remove the infected parts of the plant, improve air circulation and avoid overhead watering.
- Root rot: This is a disease caused by fungi, which attack the roots of the plant, leading to wilting and death. To prevent root rot, ensure the soil is well-draining and avoid overwatering the plant.
- Powdery mildew: This is a fungal disease that appears as white powdery spots on the leaves. To manage this disease, prune affected areas of the plant, improve air circulation, and avoid overhead watering.
Pest Management
Bidens superba Sherff var. brachycarpa Sherff can also be attacked by pests, such as aphids, spider mites, and thrips. These pests can suck sap from the plant, causing stunting, yellowing of leaves, and even death. Here are some suggestions on how to manage these pests:
- Aphids: Use insecticidal soap or neem oil to control aphids. Alternatively, you can introduce natural predators like ladybugs to your garden to help control aphids.
- Spider mites: Regularly hose down the plants with water and keep the humidity levels up to deter spider mites. Additionally, you can use neem oil or insecticidal soap to control spider mites.
- Thrips: Use sticky traps to catch thrips and keep your garden weed-free. Alternatively, you can use insecticidal soap or neem oil to control thrips.
