Planting & Care Guide

Ideal Location

Choose a site with at least six hours of direct sunlight daily. While Aster (D) ‘Peter Harrison’ tolerates light afternoon shade, too much shade can reduce flower production. Ensure soil is well-draining; raised beds or gently sloping ground help prevent root rot.

Watering

Keep soil consistently moist, especially during the first growing season. Once established, water when the top 2 cm of soil feels dry. Avoid overwatering, as soggy conditions can lead to crown rot and fungal issues.

Pruning & Maintenance

In spring, cut back old stems to ground level to encourage fresh, healthy growth. Deadhead spent blooms through mid-fall to promote continued flowering and prevent self-seeding. Apply a balanced, slow-release fertilizer in early spring for best performance.
