Cultivation Methods
Symphyotrichum ontarione (Wieg.) Nesom var. glabratum (Semple) L. Brouillet & Bouchard, also known as the Ontario Aster, is a herbaceous perennial that thrives in USDA hardiness zones 3-8. The plant prefers full sun but can tolerate partial shade. It grows best in well-draining soils rich in organic matter. Avoid planting in compacted or heavily clay soils, as this can lead to root rot. When planting, ensure that the root ball is placed at the same level as the soil surface. Space each plant at least 18-24 inches apart to facilitate air circulation. This is important in minimizing disease infestations. The plant is also drought tolerant but require regular watering to thrive.Watering Needs
Symphyotrichum ontarione (Wieg.) Nesom var. glabratum (Semple) L. Brouillet & Bouchard requires consistent watering throughout the growing period for optimum performance. Young plants need to be watered frequently until they establish a deep root system. Mature plants require deep watering once every week. Avoid watering the foliage, as this can lead to foliar diseases. During hot and dry spells, water the plant more often. Water early in the morning or late in the evening to minimize water evaporation and to ensure that the plant has sufficient moisture during the day.Fertilization
Symphyotrichum ontarione (Wieg.) Nesom var. glabratum (Semple) L. Brouillet & Bouchard doesn't require excessive fertilizer applications. Fertilize once at the beginning of the growing season and then half-way through the period using a balanced, slow-release fertilizer. Use nitrogen-rich fertilizers sparingly, as these can encourage lush, tender growth that is susceptible to diseases and pests. Alternatively, use organic fertilizers such as compost, manure, or bone meal, which provide a steady, slow-release supply of nutrients throughout the growing period.Pruning
Pruning Symphyotrichum ontarione (Wieg.) Nesom var. glabratum (Semple) L. Brouillet & Bouchard on an annual basis is essential to promote vigorous growth and good flowering. Deadheading the plant after blooms fade helps to divert the plant's energy to new bud formation, leading to a longer blooming period. During late fall or early spring, cut back the plant to the basal foliage, removing brown leaves and dead stems. This promotes good aeration and eliminates any disease or pest infestations hibernating in the plant. Avoid cutting more than half of the plant's height at a time, as this can stunt its growth and reduce blooms.Propagation of Symphyotrichum Ontarione (Wieg.) Nesom var. Glabratum (Semple) L.

Although relatively resistant to disease, Symphyotrichum ontarione may occasionally fall victim to powdery mildew, a fungal disease characterized by a white powdery coating on the leaves. This disease can cause leaf drop, stunted growth, and overall weakening of the plant.
To manage powdery mildew on Symphyotrichum ontarione, it is recommended to remove affected leaves or entire plants if the infection is severe. It is also recommended to avoid overhead watering and to provide good air circulation around the plants.
Common Pests
Symphyotrichum ontarione is generally not bothered by pests, however, there are a few that may still cause problems.
Spider mites are a common pest in dry environments and can cause leaves to turn yellow and fall off. They are small and hard to see, but can be detected by the fine webbing they leave on plants. Management of spider mites on Symphyotrichum ontarione involves removing affected leaves and spraying the foliage with water to discourage the pests.
Another pest that may affect Symphyotrichum ontarione is the leafhopper, a small insect that feeds on the leaves of plants. Leafhoppers can cause yellowing of leaves and stunted growth. Controlling leafhoppers on Symphyotrichum ontarione can be achieved by spraying the plant with insecticides designed to target them.
Overall, Symphyotrichum ontarione is a hardy plant that requires very little in terms of pest and disease management. However, vigilance and swift action are recommended if any issues do arise.
