Light: Erigeron inornatus (Gray) Gray var. angustatus Gray thrives in full to partial sunlight. It requires at least 4 hours of direct sunlight each day to grow and produce flowers. The plant cannot tolerate complete shade. Therefore, it should be planted in a location with ample sunlight.
Temperature: This plant is native to the western part of North America, and it can adapt to different temperature ranges. The ideal temperature for its growth ranges from 60 to 80 degrees Fahrenheit. It can withstand moderate frost levels, but it cannot survive in extended freezing temperatures.
Soil: Erigeron inornatus (Gray) Gray var. angustatus Gray grows best in well-draining soils, rich in organic matter. It prefers slightly acidic to neutral soil pH levels ranging from 5.5 to 7.5. Soil that is too dry will inhibit root growth and may cause the plant to wither and die, while waterlogged soil will cause root rot and other fungal diseases. Therefore, it is essential to maintain a consistent moisture level in the soil by watering regularly.
Other Growth Conditions: The plant requires a minimum of six hours of suitable growth environment conditions daily. Its adaptation ability to high temperature and drought makes it suitable for xeriscaping. It is tolerant of various soil types, from sandy loams to clay loams. It can grow in fertile or nutrient-deficient soils.
Cultivation
Erigeron inornatus var. angustatus is commonly grown in full sun, in well-draining soil that is low in nutrients.
This plant thrives in dry conditions, so it is essential to make sure the soil is not too moist. A pH range of 4.5 to 6.5 is ideal for optimal growth.
Watering Needs
Erigeron inornatus does not need frequent watering. However, it is recommended to water them once a week, especially during hot, dry weather.
Ensure to avoid overwatering and waterlogging of the soil.
Fertilization
Erigeron inornatus var. angustatus does not require heavy fertilization. It is only necessary to fertilize the plant once or twice a year.
The ideal time to fertilize is either in early spring or midsummer, using organic fertilizers or slow-release fertilizers to prevent nutrient overload in the soil.
Pruning
Erigeron inornatus var. angustatus tends to become leggy and untidy, so regular pruning is necessary to promote bushy and compact growth.
The best time to prune this plant is in late winter or early spring before new growth appears. Prune the plant back by a third of its height, removing any dead or damaged foliage.
To promote continuous blooming, it is essential to deadhead the plant regularly, removing spent flowers regularly.
Propagation of Erigeron inornatus var. angustatus
Erigeron inornatus var. angustatus, commonly known as narrowleaf fleabane, is a resilient herbaceous perennial that can be propagated through both sexual and asexual methods.
Seed Propagation
The most common method of propagating Erigeron inornatus var. angustatus is through seeds. The seeds of this plant are small and should be sown in well-draining soil. Start the seeds indoors in pots or flats in late winter to early spring.
When planting the seeds, cover them lightly with soil and keep them moist but not soaked. The seeds will take around 2 to 4 weeks to germinate. When the seedlings have grown tall enough, transfer them to individual pots or plant them in the ground.
Division Propagation
Another method of propagating Erigeron inornatus var. angustatus is through division. When the plant has grown for a few years, dig up the entire plant and divide it into smaller sections.
Make sure each section has roots and a piece of the crown. Replant each section in a well-draining soil mixture and keep the soil moist until the plant establishes. This method can be performed in early spring when the plant is starting to show new growth.
Cutting Propagation
Erigeron inornatus var. angustatus can also be propagated through cuttings. Use sterile scissors to take 3 to 4 inches of stem cuttings from the parent plant at its growth period. Make sure to remove any lower leaves and dip the cut end into rooting hormone powder or liquid to stimulate root growth.
Pot the cuttings into small pots filled with well-draining potting mix and keep them in a warm, bright area but out of direct sunlight. Make sure to keep the soil moist and mist the foliage regularly. After 4 to 6 weeks, the cuttings should show signs of rooting and can be transferred to individual pots or planted in the ground.
Disease Management
Erigeron inornatus (Gray) Gray var. angustatus Gray rarely experiences significant diseases, but it is still necessary to keep an eye out for potential problems. Here are some common diseases that might affect this plant:
- Root Rot: Erigeron inornatus is susceptible to root rot if its soil is watered excessively or if it is grown in poorly drained soil. To prevent root rot, make sure the soil is well-draining and avoid overwatering the plant.
- Powdery Mildew: Powdery mildew is a fungal disease that causes a white, powdery coating to appear on the leaves of the plant. To prevent powdery mildew, plant the Erigeron inornatus in an area with good air circulation and avoid wetting the leaves when watering.
- Virus: Viruses can cause stunted growth, yellowing and distortion of leaves in Erigeron inornatus. To prevent viruses, it's essential to ensure that the plant is grown in a healthy environment. Make sure the plant is well-nourished and not stressed, give the plant plenty of space for good airflow.
Pest Management
Erigeron inornatus (Gray) Gray var. angustatus Gray is also susceptible to insect pests. Insect pests can weaken the plants and make them vulnerable to diseases. Here are some pests that might affect this plant and how to manage them:
- Aphids: Aphids are small insects that suck sap from the leaves and stems, which can cause the leaves to curl and become distorted. To manage aphids, spray the plant with water or use insecticidal soap.
- Spider mites: Spider mites are tiny, spider-like pests that suck sap from the leaves, causing yellowing or bronzing of the foliage. To manage spider mites, increase humidity through misting, and use insecticidal soap.
- Thrips: Thrips are thin, tiny insects that can cause the petals of the plants to become discolored. To manage thrips, use a neem oil spray or insecticidal soap.
- Slugs and snails: Slugs and snails can cause large holes in the leaves and stems of the plant. To manage slugs and snails, use a physical barrier like copper tape around the base of the plant or use a beer trap to attract and drown them.
