Agapanthus Plants: Dividing, Planting & Seasonal Care for Lily of the Nile

Agapanthus forms fleshy rhizome clumps that can be divided after flowering to propagate and rejuvenate. Each division needs a shoot and healthy roots. In warm climates, replant immediately; in cold areas, store over winter and plant in spring.

Division & Planting

1. Trim foliage to ground level.
2. Loosen soil widely around clump; lift with fork.
3. Separate into smaller sections, each with roots and a bud.
4. Plant in sun, fertile, well-drained soil: 2″ deep, 4″ wide holes, 4–5″ apart.
5. Containers: 12″ pot, same depth, one division per pot.

Ongoing Care

• Water: Deep, regular watering until established; then weekly in growing season. Pots may need daily checks in summer.
• Foliage: Remove yellowing leaves at base for tidiness.
• Cut Flowers: Snip stems at desired length with sharp shears.
• Post-Bloom: Cut spent flower stalks; retain foliage to feed rhizomes.

Overwintering

Pots: move indoors. In-ground: dig, divide, store cool/dry in boxes. Replant in spring.

With minimal fuss, agapanthus delivers weeks of stunning blue spheres year after year.
