The attractive blooms and the plant’s wildlife appeal make it a valuable addition to both formal and naturalistic garden schemes.


Aster novae-angliae ‘September Ruby’ requires well-drained soil to thrive, as it is susceptible to root rot in overly moist conditions. Proper watering is essential, especially during the plant’s establishment phase and in periods of drought. It is important to ensure that the soil is moist but not waterlogged, striking the right balance to support healthy growth and blooming.


New England Asters thrive in full sun exposure, requiring at least 6 to 8 hours of direct sunlight per day. Adequate sunshine is crucial for promoting robust growth and profuse blooming, making it an ideal addition to sunny garden borders and open landscapes.


To support the vigorous growth and abundant flowering of Aster novae-angliae ‘September Ruby’, an annual application of a balanced, slow-release fertilizer in the spring is beneficial. This will provide the plant with essential nutrients to fuel its growth and promote a spectacular floral display.


The New England Aster thrives in well-drained, moderately fertile soil. A neutral to slightly acidic soil pH is preferred, ranging between 6.0 and 7.0. Organic matter can be incorporated into the soil to improve its structure and fertility, thereby supporting the plant’s overall health and vigor.


Pruning plays a crucial role in maintaining the vitality and aesthetic appeal of Aster novae-angliae ‘September Ruby’. In late spring or early summer, the plant can be pinched back to promote bushier growth and prevent it from becoming leggy. Deadheading spent blooms as they fade will encourage continuous flowering throughout the season.
