Cultivation of Aster cordifolius L. ssp. laevigatus (Porter) A.G. Jones
Aster cordifolius L. ssp. laevigatus (Porter) A.G. Jones, commonly known as blue wood aster or heart-leaved aster, is a bushy, herbaceous perennial plant that belongs to the family Asteraceae. It is endemic to the eastern parts of North America and is a popular garden plant that attracts pollinators like bees, butterflies, and hummingbirds.
When planting blue wood aster, ensure you select a site with well-drained soil that is high in organic matter. It grows best in full sun or partial shade. Plant in the spring or fall, with a spacing of about 18-24 inches between each young plant. Before settling the plant, loosen the soil and add some compost to enhance nutrients and soil structure.
Watering Needs of Aster cordifolius L. ssp. laevigatus (Porter) A.G. Jones
Water the plant deeply and evenly, particularly during its first growing season. Provide sufficient moisture to allow the plant to develop a robust root system. It is best to water frequently but lightly in hot and dry soil conditions. However, ensure you do not water till the soil becomes waterlogged, as this could cause root rot.
Fertilization of Aster cordifolius L. ssp. laevigatus (Porter) A.G. Jones
As Aster cordifolius L. ssp. laevigatus (Porter) A.G. Jones is a perennial plant, it requires regular feeding to maintain its vigor and health. Supplement the soil with a balanced fertilizer like a 10-10-10 NPK blend or organic compost. Fertilize twice a year, applying the fertilizer at the beginning of the growing season and again in midsummer.
Pruning Aster cordifolius L. ssp. laevigatus (Porter) A.G. Jones
Prune the plant regularly in spring or early summer to remove any diseased, damaged, or dying leaves. Deadheading, which means pinching off dead flowers, will help to keep the plant tidy and prolong its blooming period. However, it is best to leave some flowers on the plant towards the end of the growing season to enable self-seeding and ensure new plants the following year.
Propagation Methods of Aster Cordifolius L. Ssp. Laevigatus (Porter) A.G. Jones
Aster cordifolius L. ssp. laevigatus (Porter) A.G. Jones, commonly known as smooth heart-leaved aster, is a desirable plant for its attractive bluish-purple flowers and its ability to grow in different soil conditions. For those who would like to grow this plant, propagation is essential. Here are some methods of propagation that you can use to grow Aster cordifolius L. ssp. laevigatus at home:
Seed Propagation
The propagation of Aster cordifolius L. ssp. laevigatus can be achieved through seed propagation. The plant produces numerous seeds that can be harvested. However, it is important to note that Aster cordifolius L. ssp. laevigatus seeds require cold treatment before they can germinate. To do this, store the seeds in a dry and cool place below 40°F for about six weeks before planting. Sow the seeds in a well-draining soil mix. Cover them lightly with the soil, then spray water lightly over the soil surface. Keep the soil moist until germination occurs, which usually takes around two to three weeks.
Division Propagation
Division propagation is another way to propagate Aster cordifolius L. ssp. laevigatus. You can divide this plant in spring when it starts to grow from the ground. To divide this plant, dig up the clump, being careful not to damage the roots. Gently separate the clump into several sections, each containing a portion of the roots and shoots. Replant the new divisions in prepared soil in a suitable location. Keep the soil moist until the plant establishes, which usually takes around two to three weeks.
Cuttings Propagation
Cuttings propagation is also a method that you can use to propagate Aster cordifolius L. ssp. laevigatus. This method requires using a stem cutting from an already established plant. Take a few inches of the stem cuttings and remove the bottom leaves. Dip the cuttings in rooting hormone and plant them in a well-draining soil mix. Place the pot in a bright location but not in direct sunlight. Keep the soil moist until the cuttings have rooted and started to grow, which can take up to six weeks.
Propagation is a great way to grow Aster cordifolius L. ssp. laevigatus. Seed propagation, division propagation, and cuttings propagation are the three most common methods that you can use. Each method requires its unique technique that you can easily learn and master with time.
Disease Management
Aster cordifolius L. ssp. laevigatus (Porter) A.G. Jones is susceptible to several diseases that can cause significant damage to the plant. Here are some of the most common ones:
- Powdery mildew: This fungal disease is characterized by a powdery white coating on the leaves and stems. The affected parts may become distorted or stunted. To manage powdery mildew, remove and destroy affected plant parts and improve air circulation by spacing plants properly.
- Aster yellows: This disease is caused by a phytoplasma that is carried by leafhoppers. The symptoms include yellowing, stunting, and abnormal growth of the affected parts. There is no cure for aster yellows, so timely removal and destruction of affected plants can prevent the spread of the disease.
- Cercospora leaf spot: This fungal disease causes brown spots with yellow halos on the leaves. The affected leaves may eventually drop. To manage cercospora leaf spot, remove and destroy affected leaves, avoid overhead watering, and provide good air circulation.
- Sclerotinia stem rot: This fungal disease causes black lesions on the stems that can grow and girdle the stems. Infected plants may wilt and die. To manage sclerotinia stem rot, avoid overhead watering, improve air circulation, and promptly remove and destroy infected plants.
Pest Management
Aster cordifolius L. ssp. laevigatus (Porter) A.G. Jones is also susceptible to pests that can cause damage to the plant. Here are some of the most common ones:
- Aphids: These small insects suck sap from the plant and can cause stunted growth and distorted leaves. To manage aphids, blast them off the plant with a strong jet of water or use insecticidal soap or neem oil.
- Spider mites: These tiny pests can cause yellowing and bronzing of the leaves. They are usually found on the undersides of the leaves. To manage spider mites, improve air circulation, provide adequate moisture, and use insecticidal soap or neem oil.
- Leafhoppers: These insects can transmit aster yellows and cause stunted growth and yellowing of the leaves. To manage leafhoppers, remove and destroy affected plants and use insecticidal soap or neem oil.
Regular monitoring of the plants and prompt action to manage diseases and pests can help keep Aster cordifolius L. ssp. laevigatus (Porter) A.G. Jones healthy and thriving.
