The plant prefers fertile, well-drained soil, which is neither too soggy nor too dry. It can tolerate various soil types, including clay, loam, or sand, as long as there is good drainage. The ideal planting time is in the spring or fall seasons, when the soil is moist, and moderate temperatures prevail.
Watering Needs
The plant requires regular watering to maintain its lush green foliage and vibrant flowers. It is important to water the plant deeply, at least once a week during the growing season. However, the frequency of watering depends on the weather and soil moisture levels. Overwatering can lead to waterlogging, root rot, and fungal diseases, while underwatering can cause the plant to wilt and dry up. Hence, it is essential to keep the soil moist but not soggy.
Fertilization
Aster novi-belgii L. var. crenifolius (Fern.) J. Labrecque & L. Brouillet needs regular fertilization to promote healthy growth and blooming. It is recommended to apply a balanced fertilizer during the growing season, at least once every four to six weeks.

It is advisable to follow the manufacturer's guidelines for the correct dosage and application methods.
Pruning
Pruning is an essential activity to maintain the shape and size of the Aster novi-belgii L. var. crenifolius (Fern.) J. Labrecque & L. Brouillet plant and to remove dead or diseased foliage. The best time to prune the plant is during the early spring or late winter, before the new growth appears. It is recommended to cut back the plant to about six inches above the ground, to encourage new growth and blooming. During the growing season, it is advisable to deadhead the spent flowers regularly to promote continuous blooming and to prevent seed production.
Propagation of Aster novi-belgii L. var. crenifolius
Aster novi-belgii L. var. crenifolius (Fern.) J. Labrecque & L. Brouillet, commonly known as New York aster, is a perennial herbaceous plant native to North America. Propagation of this plant can be done through several methods:
Seed Propagation
One of the easiest ways to propagate Aster novi-belgii L. var. crenifolius is through seed propagation. The seeds can be directly sown in the garden bed in spring or fall. The ideal time for sowing the seeds is in spring when the soil has warmed up, allowing faster germination.
Division Propagation
Division is another common and effective method of propagation. The plant can be divided every 2-3 years during spring or fall. To do this, gently dig up the plant and separate the root mass into smaller pieces using a sharp knife. Each division should have a healthy root system and several shoots. The new plants can then be replanted in a pot or directly in the garden bed with well-draining soil.
Cuttings Propagation
Cuttings propagation can also be done in early summer when the plant is actively growing. Take a 4-6 inch cutting from the stem using a clean, sharp pair of scissors. Remove the lower leaves and dip the cut end in a rooting hormone. Plant the cutting in a container filled with well-draining soil and keep it moist until roots develop.
Overall, Aster novi-belgii L. var. crenifolius is a relatively easy plant to propagate through seeds, division or cuttings. With proper care, propagation would result in a collection of beautiful plants to fill up your garden.
