Aster pilosus Willd. var. platyphyllus (Torr. & Gray) Blake, commonly known as the big leaf aster, is a herbaceous plant that belongs to the Asteraceae family. It is mainly found in eastern North America.
Light Requirements
The big leaf aster thrives in partial to full sunlight. It requires about 6 hours of direct sunlight to grow and bloom to its fullest potential. Too much shade can cause leggy growth, which makes the plant weak and less able to bloom.
Temperature Requirements
Aster pilosus Willd. var. platyphyllus (Torr. & Gray) Blake prefers cooler temperatures. It can withstand frost and even light snowfall, but too much heat can damage its growth. The ideal temperature range is between 60-75°F (15-24°C) during the day and around 50-60°F (10-15°C) at night.
Soil Requirements
The big leaf aster prefers well-draining soil that is rich in organic matter. It can grow in a wide range of soil pH, but it prefers slightly acidic to neutral soil (pH 6.0-7.0). The soil should be kept consistently moist, but not waterlogged, as this can cause root rot.
Overall, the big leaf aster is a hardy plant that can thrive in a broad range of growing conditions. However, it prefers cooler temperatures, well-draining soil, and partial to full sunlight to grow and bloom to its fullest potential.
Cultivation Methods
Aster pilosus Willd. var. platyphyllus (Torr. & Gray) Blake is a sun-loving plant that thrives in well-draining soil. As such, it is important to plant it in a location that receives ample sunlight and has soil that is well-drained.

However, you can give this plant a boost by applying a general-purpose fertilizer in the spring and again in mid-summer. Be sure to follow the package instructions and avoid over-fertilizing, as this can lead to excessive leaf growth and reduced flowering.
Pruning
Aster pilosus Willd. var. platyphyllus (Torr. & Gray) Blake benefits from regular pruning to encourage bushier growth and to prevent it from becoming leggy. You can pinch back the growing tips of this plant in the spring to encourage branching, and you may also want to deadhead spent blooms to prolong the flowering season and to promote more robust growth. Pruning should be done with clean, sharp shears to avoid damaging the plant.
Propagation Methods of Aster pilosus Willd. var. platyphyllus (Torr. & Gray) Blake
Aster pilosus Willd. var. platyphyllus (Torr. & Gray) Blake, commonly known as the bigleaf aster, is a perennial plant that is native to North America. The plant is typically propagated using seeds or by division.
Propagation by Seeds
The seeds of Aster pilosus Willd. var. platyphyllus (Torr. & Gray) Blake can be sown directly in the garden in the fall or spring. Alternatively, the seeds can also be started indoors in the spring and transplanted into the garden once the weather has warmed up.
When sowing the seeds directly in the garden, make sure to plant them to a depth of 1/8 inch and keep the soil moist until the plants have germinated. To start the seeds indoors, sow them in pots or trays filled with a seed-starting mix. Keep the soil moist and warm until the seeds have germinated.
Propagation by Division
Aster pilosus Willd. var. platyphyllus (Torr. & Gray) Blake can also be propagated by division. This is best done in the spring or fall when the plant is not actively growing. To divide the plant, dig it up and carefully separate the clumps into smaller sections. Each section should have at least one healthy stem and root system.
Replant the divided sections in soil that has been amended with organic matter. Water the plants well and keep them moist until they become established. Division is a good way to propagate Aster pilosus Willd. var. platyphyllus (Torr. & Gray) Blake if you want to create additional plants or if the original plant has become too large and needs to be divided to prevent overcrowding.
Disease Management
Aster pilosus Willd. var. platyphyllus (Torr. & Gray) Blake plant can experience several diseases that may affect its growth and reduce its production. Some of the common diseases that may affect this plant include:
- Powdery mildew: this disease is characterized by a white, powdery coating on the leaves and stem of the plant. To manage this disease, you can remove the affected plant parts, ensure the plant has proper air circulation, and apply fungicides like neem oil or potassium bicarbonate.
- Septoria leaf spot: this disease causes the leaves of the plant to develop grayish-brown spots. To control the spread of this disease, you can remove the affected plant parts, ensure the plant has proper air circulation, and apply fungicides like copper-based products or chlorothalonil.
- Botrytis blight: this disease causes the plant to develop a fuzzy gray mold. To manage this disease, you can remove the affected plant parts, ensure the plant has proper air circulation, and apply fungicides like captan or thiophanate-methyl.
Pest Management
Several pests may attack Aster pilosus Willd. var. platyphyllus (Torr. & Gray) Blake plant, and these pests can reduce the plant's growth and production. Some of the common pests that may attack this plant include:
- Aphids: these small insects feed on the sap of the plant and can cause the leaves to curl and turn yellow. To manage this pest, you can remove the affected plant parts, introduce natural predators like ladybugs, or apply insecticides like neem oil or insecticidal soap.
- Spider mites: these pests are tiny and may cause yellowing of the leaves and fine webbing on the plant. To manage this pest, you can remove the affected plant parts, increase humidity around the plant, or apply insecticides like neem oil or insecticidal soap.
- Leafhoppers: these pests cause yellowing and curling of the leaves. To manage this pest, you can remove the affected plant parts, introduce natural predators like lacewings, or apply insecticides like neem oil or insecticidal soap.
It is essential to properly identify the specific pest or disease affecting your plant to select the most appropriate treatment method. Also, ensure to follow the recommended guidelines for the application of any chemical control measures.
