Cultivation
Erigeron pumilus Nutt. var. euintermedius Cronq., commonly known as Green Fleabane, is a herbaceous perennial plant that belongs to the Asteraceae family. It is native to North America, found in several states, including Minnesota, North Dakota, and Wisconsin.
When cultivating this plant, ensure it is planted in well-draining soil that can hold moisture. Plant it in an area that receives full sun to partial shade. Green Fleabane thrives in areas that are exposed to direct sunlight for at least six hours a day.
It is essential to maintain a consistent watering schedule for this plant as it does not tolerate drought conditions. However, too much water can lead to root rot and may be detrimental to the plant's growth.
Watering Needs
Green Fleabane requires moderate watering. A general rule of thumb is to water plants once a week during the growing season, and increase frequency during hot weather. However, reduce watering in winter as the plant becomes dormant.
It is also good practice to check the soil's moisture level frequently, either by using a moisture meter or checking the soil's surface. Water the plant once the top inch of soil feels dry.
Fertilization
Green Fleabane is a light feeder and does not require a lot of fertilization. A balanced, all-purpose fertilizer can be applied during spring to help promote growth. Avoid over-fertilizing the plant as it can lead to weak growth and susceptibility to diseases.
It is also good practice to amend the soil with compost or organic matter to boost soil fertility.
Pruning
Pruning Green Fleabane is not necessary, but it can help promote bushier, more compact growth. Prune back the plant by cutting off a third of its total length in late spring or early summer after flowering. This will encourage the plant to produce new, compact foliage and promote growth.
Also, deadhead spent flowers regularly throughout the growing season to keep the plant looking neat and tidy. Remove yellow or brown leaves and trim back any suckers growing from the base of the plant to maintain its shape.
Propagation of Erigeron pumilus Nutt. var. euintermedius Cronq.
Erigeron pumilus Nutt. var. euintermedius Cronq. can be propagated through seeds, divisions, and cuttings. Each method has its own advantages and disadvantages and can be used depending on the grower's preference and availability of resources.
Propagation Through Seeds
Seeds are the most common way of propagating Erigeron pumilus Nutt. var. euintermedius Cronq. This method requires collecting mature seeds from the plant and then sowing them in well-prepared soil. The soil should be kept moist, and it takes about two to three weeks for the seeds to germinate. Once the seedlings have grown to a height of about 6 inches, they can be planted in the field or pots.
Propagation Through Divisions
Propagation through divisions is another method of propagating Erigeron pumilus Nutt. var. euintermedius Cronq. In this method, the plant is divided into smaller pieces, with each piece having its own roots and leaves. This is done by digging up the plant and dividing it into smaller pieces. Each piece can then be replanted in a separate location in the garden.
Propagation Through Cuttings
Propagation through cuttings is a third method of propagating Erigeron pumilus Nutt. var. euintermedius Cronq. This method involves taking cuttings from the plant and then rooting them in soil. This is done by taking a cutting from a healthy plant, stripping the lower leaves, and then planting the cutting in a container with moist soil. The container should be kept moist and in a warm location until roots develop. Once roots have developed, the new plant can be moved to a field or pot.

Powdery mildew: Powdery mildew is a fungal disease that causes a white powdery coating on the leaves. It can usually be controlled by removing the affected parts of the plant and keeping the leaves dry. You can also apply a fungicide to the plant, following the manufacturer's instructions.
Rust: Rust is a fungal disease that causes orange or brownish rust-colored spots on the leaves. To control rust, remove the affected leaves and apply a fungicide. You should also make sure the plant has good air circulation because rust thrives in moist environments.
Pests
Aphids: Aphids are small insects that suck the sap out of the plant, causing it to wilt. You can remove them by spraying the plant with a strong jet of water or applying insecticidal soap. If the infestation is severe, you may also need to use a systemic insecticide.
Spider mites: Spider mites are tiny, red or yellow insects that spin webs on the leaves of the plant. You can control spider mites by applying an insecticidal soap or horticultural oil. You should also make sure the plant has good air circulation and is not too dry because spider mites thrive in hot, dry environments.
Slugs and snails: Slugs and snails can cause damage to the leaves and stems of the plant. You can control them by using slug and snail baits or by handpicking them off the plant. You should also make sure the area around the plant is free of debris because slugs and snails like to hide in damp, dark places.
