PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: The best time to plant Symphyotrichum (Aster) ageratoides ‘Asran’ is in the spring when the soil has warmed up. This allows the plant’s roots to establish before the flowering season begins.
Autumn: Alternatively, planting in early autumn can be successful as it gives the plant time to settle in and establish before the colder months arrive.
Site Selection
Sunlight: Aster thrives in full sun to partial shade. Choose a location that receives at least 4-6 hours of sunlight per day to encourage optimal flowering.
Soil: This plant prefers well-drained soil and will not tolerate waterlogged conditions. Ensure that the site has good drainage, and amend the soil with compost or organic matter to enhance fertility and structure.
Planting Instructions
Prepare the Hole: Dig a hole that is twice as wide and the same depth as the root ball of the plant. This provides enough space for the roots to spread and grow freely.
Soil Preparation: Mix well-rotted compost or organic material into the soil to improve drainage and fertility. This will create a nutrient-rich environment for the plant to thrive.
Planting: Position the plant in the hole so the top of the root ball is level with the surrounding soil. Gently backfill with soil, firming it down to eliminate air pockets.
Watering After Planting: Water thoroughly after planting to help settle the soil around the roots. Ensure the soil drains well to prevent waterlogging.
Watering Requirements
Growing Season: Symphyotrichum (Aster) ageratoides ‘Asran’ prefers consistently moist soil during its growing season. Water regularly, especially during dry spells, but allow the soil to dry out slightly between waterings to prevent root rot.
Dormant Season: In the winter months, reduce watering. Only water the plant if the soil becomes excessively dry, as it requires minimal moisture during dormancy.
Feeding
Spring: Apply a balanced fertiliser in early spring to support strong growth and encourage vibrant blooms. Aster benefits from a nutrient boost at the start of the growing season.
Mid-Summer: A light feeding in mid-summer will help maintain growth and extend the blooming period, ensuring that the plant continues to produce flowers well into autumn.
Pruning
Deadheading: Regularly remove spent flowers to encourage continuous blooming. Deadheading also helps keep Symphyotrichum (Aster) ageratoides ‘Asran’ looking tidy and can prolong its flowering season.
Autumn Pruning: Once flowering has finished, trim back the plant to ground level. This prepares Aster) ageratoides ‘Asran’ for the winter and ensures fresh growth for the following year.
Mulching
Spring: Apply a 2-3 inch layer of organic mulch around the base of the plant in spring to retain moisture, suppress weeds, and regulate soil temperature.
Winter: In colder months, add an extra layer of mulch to protect the roots from frost and to prevent soil erosion during the winter rains.
Supporting the Plant
Symphyotrichum (Aster) ageratoides ‘Asran’ grows to a height of 70-80cm and has a strong, bushy structure, so staking is rarely necessary. However, in very windy locations, it may be beneficial to add support to prevent any wind damage, especially during heavy blooms.
