Light Requirements
Aster bakerianus Burtt Davy ex C.A.Sm. subsp. ovalis W.Lippert typically requires full sun exposure to grow and thrive. The plant prefers at least six hours of direct sunlight each day. In areas with intense heat and sunshine, some light shading during mid-afternoon may be necessary to prevent scorching and sun damage.
Temperature Requirements
This plant requires moderate temperatures for optimal growth and development. The ideal temperature range for Aster bakerianus Burtt Davy ex C.A.Sm. subsp. ovalis W.Lippert is between 20 and 25 °C. However, the plant can tolerate temperatures ranging from 10 to 30 °C. In extremely hot climates, the plant may require regular watering to prevent heat stress.
Soil Requirements
Aster bakerianus Burtt Davy ex C.A.Sm. subsp. ovalis W.Lippert prefers well-drained soils that are rich in organic matter. The plant can grow in a range of soil types, including loamy, sandy, or rocky soils. However, the soil should have a pH of 6.0 to 7.5 for optimal growth. Poorly drained soils may lead to root rot, which can cause damage to the plant's root system and affect its overall growth and development.
Cultivation methods
Aster bakerianus Burtt Davy ex C.A.Sm. subsp. ovalis W.Lippert is a perennial plant that can grow up to 50 cm in height. It prefers full sunlight or partial shade in well-drained soil with a pH between 6.5 and 7.5. The plant can be propagated by sowing seeds in late winter or through division in early spring. The seedlings should be thinned out to about 10 cm apart to allow for proper growth.
Watering needs
Watering should be done regularly, especially during dry periods, to keep the soil evenly moist. Overwatering should be avoided as it can lead to root rot. Irrigation can be done using a drip system or by hand, making sure not to wet the foliage as this can cause fungal diseases. Mulching can also help retain moisture in the soil.
Fertilization
Aster bakerianus Burtt Davy ex C.A.Sm. subsp. ovalis W.Lippert does not require frequent fertilization. However, a balanced fertilizer can be applied once in early spring after the last frost. Another application can be done in mid-summer to encourage blooming. Avoid using high-nitrogen fertilizers as they can promote lush foliage growth at the expense of flowering.
Pruning
Pruning is not necessary for Aster bakerianus Burtt Davy ex C.A.Sm. subsp. ovalis W.Lippert. However, deadheading spent flowers can prolong the blooming period. The plant can be cut back to about 10 cm above the ground after the first frost in fall to tidy up the garden bed and promote new growth in spring.
