Regardless of the propagation method used, Erigeron asperum Nutt. p.p. is easy to propagate and has a high success rate. With proper care and attention, the plant will grow quickly and produce beautiful, vibrant flowers.
Disease Management
Erigeron asperum Nutt. p.p. is not known to be particularly susceptible to many diseases but can be affected by a few fungal and bacterial infections. Here are some of the common diseases that may affect the plant:
- Leaf spot: This is caused by the fungus Cercospora and appears as small, brown or black spots on the leaves. To manage this, remove infected leaves and avoid overhead watering to prevent water from splashing on the foliage. Apply fungicides if necessary.
- Powdery mildew: This fungal infection appears as a white, powdery coating on the leaves. Prevent this disease by ensuring adequate air circulation and avoid overhead watering. Apply fungicides if necessary.
- Crown rot: This is caused by a fungal or bacterial infection and results in the plant's crown turning brown and mushy. To prevent crown rot, avoid overwatering and plant in well-draining soil.
Pest Management
Erigeron asperum Nutt. p.p. is also prone to attacks from a few common pests, including:
- Spider mites: These tiny pests can be identified by the presence of webbing on the plant and yellow or brown speckling on the leaves. To manage the infestation, spray the plant with insecticidal soap or neem oil. Wipe the leaves with a damp cloth to remove any dust that can provide a habitat for the mites.
- Aphids: These small, pear-shaped pests can be green, black, or brown and are usually found on the undersides of leaves. To manage aphids, spray the plant with a strong stream of water or insecticidal soap. Ladybugs and lacewings can also be introduced to the garden as natural predators of aphids.
- Slugs and snails: These pests can be controlled by creating barriers around the plant using copper tape or diatomaceous earth. Beer traps can also be used to lure them away from the plant.
