The plant produces many daisy-like flowers that range in color from white to lavender-pink. The center of the flowers is yellow and may have black markings. The plant blooms in the summer and early fall.
Growth Conditions for Erigeron acris auct. non L. p.p.
Erigeron acris auct. non L. p.p., also known as the Eastern Dune Fleabane, is an herbaceous plant that grows in sandy or gravelly soils, near the coastal beaches. Here are the typical growth conditions for this plant:
Light Requirements
Erigeron acris auct. non L. p.p. is a sun-loving plant and requires full sunlight for proper growth. It needs at least 6 hours of direct sunlight each day to thrive. Therefore, it is essential to plant this species in a location with ample sunlight to achieve optimal growth.
Temperature Requirements
The Eastern Dune Fleabane thrives in warm temperatures, and it is known to tolerate high heat. The ideal temperature range for this plant is between 65°F to 80°F (18°C to 27°C). It cannot survive in areas with frost and excessive rainfall, which can lead to root rot and stunted growth.
Soil Requirements
Erigeron acris auct. non L. p.p. prefers well-draining, sandy or gravelly soils with high levels of organic matter. It can also tolerate slightly acidic to slightly alkaline soil, with pH ranging between 5.0 to 8.0. This plant cannot survive in compacted soils or areas with standing water, as these conditions can lead to poor root development and plant death.
In conclusion, Eastern Dune Fleabane requires a sunny and warm environment, with well-draining sandy to gravelly soil. These optimal growth conditions are crucial for the survival and growth of this plant species.
Cultivation Methods
Erigeron acris auct. non L. p.p. is a perennial plant that grows well in almost all regions. It requires well-drained soil and full sun to thrive. The plant can tolerate partial shade, but it may affect its growth.
The plant is propagated through seeds or by cutting. For propagation using seeds, start by stratifying the seeds for a few weeks before planting. For propagation by cutting, use stem cuttings from mature plants.
When transplanting the plant, ensure that it is planted at the same depth as it was in the previous location. Water the plant thoroughly and keep the soil moist until it establishes in its new site.
Watering Needs
Erigeron acris auct. non L. p.p. thrives in moist soil but is also tolerant of drought. Water the plant deeply once a week when the weather is dry to ensure the soil is moist to a depth of at least 6 inches. Avoid overwatering, as the plant does not tolerate water-logged soil.
Fertilization
Erigeron acris auct. non L. p.p. does not require much fertilization. Apply a balanced fertilizer once a year in the early spring to promote growth and flowering. Too much fertilizer may lead to excessive foliage growth, which affects the number of blooms.
Pruning
The plant does not require extensive pruning. Deadhead flowers as they fade to encourage more blooms. Cut back the plant by half to two-thirds of its height in late fall or early spring to prevent disease and promote bushy growth. Remove any damaged, dead, or diseased stems to keep the plant healthy and attractive.
Propagation of Erigeron acris auct. non L. p.p.
Erigeron acris auct. non L. p.p. is a perennial plant that can be propagated by various methods, including seeds, cuttings, and division.
Propagation by Seeds
Seeds are the most common way to propagate Erigeron acris auct. non L. p.p. To produce new plants from seeds, they must be collected from the parent plant when they are mature (usually from late summer to early fall). The seeds should be stored in a cool and dry place until it is time for sowing. Sow the seeds in well-drained soil and keep the soil moist until the plants are established.
Propagation by Cuttings
Erigeron acris auct. non L. p.p. can also be propagated by stem cuttings. Cuttings should be taken from the parent plant in the spring or early summer. The cuttings should be several inches long and should have at least two sets of leaves. Remove the lower leaves and put the cutting in moist soil. Keep the soil moist and the cutting in a shaded area until it starts to grow roots. Once the roots have formed, move the new plant to a sunny area.
Propagation by Division
Erigeron acris auct. non L. p.p. can also be propagated by division. This method involves digging up the plant and dividing it into several sections, each with its own root system. This can be done in the spring or fall. Each section should have several stalks and at least one set of leaves. Replant each division in a well-draining soil in a sunny area and keep the soil moist until new growth appears.
Disease Management:
Erigeron acris is generally hardy and resistant to most diseases, but it may still fall prey to some common plant diseases, such as:
- Fungal Diseases: Fungal diseases like root rot and powdery mildew may affect the plant. To prevent fungal diseases, ensure the soil is well-draining and avoid over-watering the plant. If already infected, apply a fungicide to slow down its spread.
- Bacterial Diseases: Bacterial diseases like bacterial wilt can cause the death of the plant. To prevent bacterial diseases, practice good sanitation and maintain proper soil pH. If already infected, remove and destroy the affected plant parts and reduce irrigation.
Pest Management:
Erigeron acris may also be attacked by some common pests. Here are a few common pests that might affect the plant and ways to manage them:
- Aphids: Aphids are small, soft-bodied insects that excrete a sticky substance and can cause the plant to wilt. To control aphids, apply an insecticidal soap or a neem oil solution on the affected plants.
- Spider mites: Spider mites are tiny pests that form webs between the leaves and feed on the plant. To control spider mites, apply a miticide to the plant at the first signs of infestation and improve air circulation around the plant.
- Whiteflies: Whiteflies are tiny insects that suck plant sap, resulting in yellow leaves. To control whiteflies, apply a sticky trap or introduce biological control agents like parasitic wasps and predators like ladybugs.
