📅 Maintenance Schedule — Plant Care Comparison

Plume Poppy

Repotting N/A (Outdoor plant)
Pruning Cut back spent flower stalks after blooming to encourage tidiness and prevent self-seeding. Remove any dead or damaged foliage.
Fertilizing Apply a balanced slow-release fertilizer in early spring. Avoid over-fertilizing, as this can promote excessive foliage growth at the expense of flowering.
Seasonal Care In spring, apply fertilizer and divide if necessary. In summer, ensure adequate watering. In fall, cut back spent flower stalks. In winter, the plant will go dormant.

Rudbeckia

Repotting Not applicable as it's primarily an outdoor plant. If grown in containers, repot every 1-2 years in spring.
Pruning Deadhead spent flowers to encourage continued blooming. Cut back foliage in late fall or early spring.
Fertilizing Balanced fertilizer (10-10-10) at half strength every 4-6 weeks during the growing season (spring and summer).
Seasonal Care In spring and summer, provide regular watering and fertilization. In fall, allow seed heads to remain for birds or collect seeds for propagation. In winter, cut back dead foliage.
