Temperature Requirements:
Aster dumosus L. var. strictior Torr. & Gray prefers moderate temperatures. The ideal temperature range is between 60 to 70 degrees Fahrenheit. The plant can withstand a minimum temperature of 50 degrees Fahrenheit and a maximum temperature of 80 degrees Fahrenheit.

Cultivation Methods
Aster dumosus L. var. strictior Torr. & Gray, commonly known as bushy aster, is a popular perennial herbaceous plant that thrives well in well-draining soils. The best planting time is from early spring to late fall when the soil is workable. Bushy aster prefers full sun but can tolerate partial shade. The plant needs enough room to spread its roots, and it's essential to maintain a spacing of about 12-18 inches.
Watering Needs
Bushy aster needs regular watering to ensure proper growth and development, especially during its first year after planting. It's crucial to keep the soil moist during the growing season, but it's equally essential not to overwater the plant as it can lead to root rot. The best practice is to water the plant deeply once per week when there is no rainfall.
Fertilization
Applying fertilizer is crucial in enhancing the growth and flowering of Aster dumosus L. var. strictior Torr. & Gray. Use a balanced fertilizer with an N-P-K ratio of 10-10-10 or 12-12-12 during the growing season. It's best to apply the fertilizer early in the spring and then every four to six weeks, following the manufacturer's instructions. Overfertilization should be avoided as it can lead to weak stems.
Pruning
Pruning bushy aster is essential to keep the plant healthy and bushy. It's best to prune the plant in early spring before new growth appears. Cut back the plant to a height of about 6-8 inches to encourage a more compact shape. Deadheading spent flowers during the flowering season will encourage continued blooming. Also, it's essential to cut back the plant in the late fall to about 2-3 inches to prevent winter damage.
Propagation of Aster Dumosus L. Var. Strictior Torr. & Gray
Aster dumosus L. var. strictior Torr. & Gray, commonly known as bushy aster or stiff aster, is a beautiful perennial plant that belongs to the family Asteraceae. It is native to North America and Canada and is widely cultivated for its showy flowers.
Propagation by Seeds
One of the most common ways to propagate Aster dumosus L. var. strictior Torr. & Gray is through seeds. To start, collect the seeds from the plant when they are fully matured. Afterward, plant the seeds in seed-starting trays filled with well-draining soil. Cover the seeds lightly with soil and water them lightly. Afterward, keep the seeds in a warm and humid place, and germination should start in about 1-3 weeks. Once the seedlings have grown big enough, transplant them to their permanent location in your garden.
Propagation via Division
Another way to propagate Aster dumosus L. var. strictior Torr. & Gray is via division. To propagate this plant through division, start by digging up the mature plant in early spring or fall. Afterward, carefully separate the plant into several sections making sure that each section has enough roots and shoots. Afterward, plant these sections in their permanent location and water them thoroughly.
Propagation using Stem Cuttings
Aster dumosus L. var. strictior Torr. & Gray can also be propagated through stem cuttings. Take a cutting from the stem of a mature plant in the summer and dip it into a rooting hormone. Plant the cuttings into a well-draining soil mixture and keep them in a humid and warm place. In about 2-3 weeks, roots should start to form. Afterward, transplant the cuttings into your garden to grow into mature plants.
Disease Management
The plant Aster dumosus L. var. strictior Torr. & Gray is susceptible to various diseases that can damage the plant and lower its overall health and productivity. Some of the common diseases affecting the plant include:
- Botrytis blight: This is a fungal disease that causes the leaves and stems to turn brown and wilt. The leaves may also develop spots or yellowing. To manage this disease, avoid overhead watering, improve air circulation, and remove infected plant debris.
- Powdery mildew: This is a fungal disease that causes a white powdery growth on the leaves, stems, and flowers. To manage this disease, remove infected plant parts and improve air circulation.
- Septoria leaf spot: This is a fungal disease that causes circular, brown or black spots on the leaves. To manage this disease, remove and destroy infected leaves, avoid overhead watering and improve air circulation.
Pest Management
There are various pests that can attack the plant Aster dumosus L. var. strictior Torr. & Gray. Some of the common pests include:
- Aphids: These are small, soft-bodied insects that suck sap from the leaves and stems. To manage aphids, use insecticidal soap or neem oil.
- Spider mites: These are tiny insects that can cause the leaves to become yellow and speckled. To manage spider mites, use insecticidal soap or neem oil.
- Leafhoppers: These are small, wedge-shaped insects that can cause stippling and yellowing of the leaves. To manage leafhoppers, use insecticidal soap or neem oil.
