Erigeron subtrinervis Rydb. ex Porter & Britt., commonly known as subalpine fleabane, is a herbaceous perennial plant native to the western region of North America. This plant has a moderate growth rate and is easy to propagate through several methods.
Seed Propagation
Propagation of Erigeron subtrinervis through seeds is a common and efficient method. Seeds can be directly sowed into the ground or started indoors. The ideal time to sow seeds is during the fall or early spring, depending on the location and weather. The seeds need to be mixed with sand or any other growing medium to aid in even distribution. The soil should be moist, and the seeds should be placed at a depth of about ¼ inches. Germination usually takes from 2 to 4 weeks.
Once the seedlings have sprouted their true leaves, they can be transplanted into their final location. The location should be in full sun or partial shade, as Erigeron subtrinervis is adapted to a wide range of growing conditions. It is recommended to space the plants at least 2 feet apart as they can spread up to 2-3 feet in diameter.
Division
Another way to propagate Erigeron subtrinervis is through division. This method is best suited for an already established plant as it requires an already developed root system. Division is best done during the fall or early spring when the plant is dormant and is not actively growing. The plant should be lifted from the ground with care, and the root system can be divided into sections, each containing a few stems. Each section should be replanted into the ground immediately, ensuring that each newly planted section receives adequate water.
Cuttings
Erigeron subtrinervis can also be propagated through stem cuttings. For this method, a cutting is taken from the plant, and the lower leaves are trimmed to create a bare stem. The cutting should be approximately 3-4 inches in length and inserted into the rooting hormone before being placed into a growing medium. The growing medium should be kept moist, and cuttings should be kept out of direct sunlight. After the roots have developed, the new plant can be transplanted into the garden bed.
In conclusion, Erigeron subtrinervis Rydb. ex Porter & Britt. is an easy-to-grow plant that can be propagated through seed, division, or cuttings. Through these propagation methods, one can easily create healthy and vibrant new plants.

Erigeron subtrinervis Rydb. ex Porter & Britt., commonly known as three-nerve fleabane, is a hardy native North American wildflower that grows in meadows, open woods, and disturbed sites. While this plant is relatively disease and pest-resistant, there are still a few pathogens and insects to watch out for.
Common Diseases
Three-nerve fleabane is susceptible to root rot caused by overly damp soils that stagnate and grow Pythium and Phytophthora fungi.

Fungal infections can be treated with fungicides, but it is best to take preventive measures as far as possible. Make sure the plant is spaced and receives enough air circulation from other plants around it. Also, ensure that all tools and equipment are sterilized between uses.
Common Pests
While Erigeron subtrinervis is comparatively resistant to pests, some insects like aphids and spider mites can occasionally feed on its leaves. These pests can be controlled with insecticidal soaps or horticultural oils. Alternatively, prune affected leaves and discard them to avoid the insects' spread. Whiteflies can be knocked down by spraying water on the plants, or they can be managed using sticky traps. Deer and rabbits find the plant attractive and will feed on it, too. Erecting a physical barrier like a fence or using a deer repellent spray can help keep these animals away.
In conclusion, disease and pest problems are minimal for Erigeron subtrinervis. Maintaining good watering habits, sanitation, and keeping an eye on the plant's development can keep most pathogens and pests at bay.
