This particular species, potted for convenience, should be spaced adequately to accommodate its bushy spreading growth habit. Upon planting, ensure regular watering to establish a robust root system, as the plant has an average water need. To maintain vitality, division is encouraged; spring or autumn is the ideal time to separate and replant the divisions, fostering healthy development and rejuvenation.

Pruning a Aster lateriflorus 'Horizontalis'

Pruning of Aster lateriflorus 'Horizontalis' should be conducted in late winter or early spring, just as new growth begins to appear. This timing allows the plant to conserve energy and produce robust blooms come autumn.

Regular deadheading during the blooming season can also promote further flowering and prevent the plant from becoming leggy.

Watering a Aster lateriflorus 'Horizontalis'

Aster lateriflorus 'Horizontalis' thrives with consistent moisture, especially during its active growth and blooming period in late summer and early autumn. It is crucial to provide the plant with water if there are extended periods of dryness, as it is not drought-resistant. The soil should remain well-drained to prevent waterlogging, which can be detrimental to the plant's health. Water at the base to keep the foliage dry and to reduce the risk of issues caused by excess moisture on the leaves. As the plant matures, its average water needs should be met with deeper, less frequent watering to encourage a strong root system.

Fertilising a Aster lateriflorus 'Horizontalis'

To ensure the vigorous growth and prolific blooming of Aster lateriflorus 'Horizontalis', a strategic fertilization regimen should be employed. Begin by applying a balanced, slow-release fertilizer in the early spring to support the initial growth spurt. A second application should be made just before the onset of the flowering period in late summer to promote a robust display of pink and white blossoms.

When fertilizing, distribute the product evenly around the base of the plant, taking care to avoid direct contact with the foliage to prevent potential burn. Water the soil thoroughly after application to help integrate the nutrients into the root zone where they can be readily absorbed. This approach will not only enhance the autumnal floral show but also strengthen the plant's overall health.
