Propagation of Erigeron subtrinervis Rydb. ex Porter & Britt. ssp. conspicuus (Rydb.) Cronq.
Erigeron subtrinervis Rydb. ex Porter & Britt. ssp. conspicuus (Rydb.) Cronq., commonly known as the Conspicuous Fleabane, is a perennial plant that can be propagated through several different methods.
Seed Propagation
One of the most common methods of propagating Erigeron subtrinervis ssp. conspicuus is through seeds. The seeds can be collected from mature plants once the flowers have finished blooming and the seed heads have dried out. These seeds can be sown directly into the soil in the fall or early spring.
Before planting the seeds, it is recommended to scarify them, either by lightly nicking the seed coat with a file or soaking them in water for a few hours, to help with germination. Once the seeds have been scarified, they can be planted about 1/8 inch deep in a well-draining soil mixture.
The seeds will germinate in about 2-3 weeks, and the seedlings can be transplanted into their final growing location once they have developed their second set of true leaves.
Division
Another method of propagating Erigeron subtrinervis ssp. conspicuus is through division. This method can be done in the spring or fall when the plant is not actively growing. The root ball can be dug up and divided into sections using a sharp knife or garden shears.
Each section should have a few healthy shoots and roots and can be replanted immediately in a prepared soil mixture. It is important to keep the newly divided plants well-watered and shaded for the first few days to help them adjust to their new location.
Stem Cuttings
Erigeron subtrinervis ssp. conspicuus can also be propagated by taking stem cuttings. This method should be done in late spring or early summer when the plant is actively growing.
The stem cuttings should be about 4-6 inches long and should have at least a few leaves and nodes. Remove the lower leaves and dip the cut end in rooting hormone powder. Plant the cuttings in a prepared soil mixture and keep them well-watered and shaded until they develop roots and begin to grow.
Propagation of Erigeron subtrinervis ssp. conspicuus can be done through seeds, division, and stem cuttings, allowing for the expansion of your garden or the sharing of the plant with friends and neighbors.

Common Pests
Erigeron subtrinervis is relatively pest-resistant, but it can be vulnerable to some insects. One common pest that can affect the plant is the aphid. These small insects suck sap from the plant, which can weaken it and make it more susceptible to other pests and diseases.
The plant can also be affected by spider mites. These tiny pests feed on the plant's leaves, causing yellowing, stunted growth, and in severe cases, death of the plant.
Disease and Pest Management
To prevent powdery mildew, it is important to plant Erigeron subtrinervis in well-draining soil and avoid overhead watering. If powdery mildew does occur, removing the affected leaves and applying a fungicide can help manage the disease.
To prevent root rot, it is important to plant Erigeron subtrinervis in well-draining soil and avoid overwatering. If root rot does occur, removing the affected plant and improving soil drainage can help manage the disease.
To prevent aphids, it is important to monitor the plant regularly and remove any infested leaves or stems. In severe cases, applying an insecticide may be necessary.
To prevent spider mites, it is important to maintain a high level of humidity around the plant and avoid drought stress. If spider mites occur, applying a miticide can help manage the pest.
Overall, proper plant care and monitoring can go a long way in preventing and managing diseases and pests that can affect Erigeron subtrinervis Rydb. ex Porter & Britt. ssp. conspicuus (Rydb.) Cronq.
