Light Requirements
Symphyotrichum chilense grows well in full sunlight or partial shade. However, it primarily prefers a sunny location, and that can be beneficial for blooming and growth. Adequate sunlight helps this plant synthesize enough energy for photosynthesis, which is essential for its growth.
Temperature Requirements
The plant is native to regions with a temperate climate, and as such, it requires an average temperature range of 15°C - 20°C (59°F - 68°F) for optimal growth. In colder seasons or regions, the plant may go dormant, and growth may slow down. Prolonged exposure to frost or extremely hot temperatures might cause the plant to wilt and ultimately die.
Soil Requirements
Symphyotrichum chilense prefers soils that are well-drained and easy to work with. The ideal pH for this plant ranges from 6.5 - 7.5. Additionally, the plant is tolerant to a wide range of soil types, including sandy, loamy, and clay soils. However, planting it in a fertile soil that is enriched with organic matter, such as compost or well-rotted manure, is beneficial for growth and health. The plant requires moderate watering to thrive, and it is vital to ensure that the soil is not water-logged as it can cause root rot and other diseases.
Cultivation methods for Symphyotrichum chilense (Nees) Nesom
Symphyotrichum chilense (Nees) Nesom is a hardy plant that can grow in a variety of soil types and conditions. It prefers a well-draining soil that is rich in organic matter. The plant can be propagated by seeds or division of the roots.
Sow the seeds in spring after the last frost or in fall. Make a shallow trench about 1/4 inch deep and scatter the seeds about 2 inches apart. Cover the trench with soil and water thoroughly. The seeds will germinate in 2-3 weeks if kept moist.
If transplanting, choose a spot that gets full sun or partial shade. Make sure the soil is loose and fertile. Dig a hole about the same depth as the plant’s container, remove the plant from the container, and place it in the hole. Fill in the hole with soil and water thoroughly.
Watering needs for Symphyotrichum chilense (Nees) Nesom
It's essential to keep the soil consistently moist but never waterlogged for this plant. Water the plant deeply once a week or more frequently if growing in hot, dry conditions. During winter, reduce watering to avoid waterlogging.
Before watering, check the soil moisture level by sticking your finger two inches into the soil. If the soil is dry, then it's time to water.
Fertilization needs for Symphyotrichum chilense (Nees) Nesom
During the growing season, fertilize the plant every four to six weeks with a balanced fertilizer. Use a fertilizer with a higher proportion of phosphorus, which will promote the development of more flowers.
Alternatively, incorporate compost into the soil in spring to provide the plant with all the necessary nutrients it needs for the whole growing season
Pruning Symphyotrichum chilense (Nees) Nesom
Symphyotrichum chilense (Nees) Nesom does not require extensive pruning. However, you can pinch off the tips of the stems to promote bushier growth and more blooms.

Once the seedlings are big enough, you can transplant them into individual pots or directly into the garden.
Propagation by division
Division is a popular propagation method for mature plants of Symphyotrichum chilense. Divide the plant in the early spring or fall when the plant is dormant. Carefully dig up the plant and gently loosen the soil around the root ball. Separate the small plantlets from the parent plant and replant them in a well-draining soil mix. Ensure the plantlets have enough moisture and place them in a sunny location until they are established.
Propagation by cuttings
Cuttings are another propagation method for Symphyotrichum chilense. Take cuttings from the parent plant in the spring or early summer. Cut a 4-6 inch long stem with a sharp and sterilized cutting tool. Remove the lower leaves from the stem and dip the cut end in a rooting hormone. Plant the cuttings in a well-draining soil mix and keep them moist and in a warm, bright location. The cuttings should root in about 4-6 weeks and can be transplanted into individual pots or directly into the garden.
Overall, with the right propagating methods, it is easy to propagate Symphyotrichum chilense and enjoy its beautiful flowers in your garden.
