• Deadheading – Remove spent flower spikes to encourage further blooming and maintain a tidy appearance.
• Pruning – Cut back old or damaged leaves in late autumn or early spring to encourage fresh, new growth.
• Mulching – Apply a layer of mulch in autumn to protect roots during winter and improve soil fertility.
