The African lily, also known as Agapanthus, originates from South Africa and has become a popular choice for gardens in zones 7-10 and homes in regions below zone 7. With stunning blue flowers, it’s no surprise this plant is a favorite. While there are 6 to 10 species (depending on who you ask), what really matters is the beauty they bring to your space.

Agapanthus plants love growing in clusters, but overcrowding can be an issue. Dividing them not only keeps them healthy but also lets you create more plants to enjoy or share as gifts. Given how pricey these plants can get, that’s a definite win!

When to Divide Agapanthus?

Dividing is essential for both maintenance and propagation. Most agapanthus plants should be divided every 4 to 5 years, while deciduous varieties can wait 6 to 8 years. The best time to divide them is either in spring, after the final frost, or in early fall once the plant has finished flowering or its leaves have fallen.

How to Divide Agapanthus:

1. Preparation: Gather a sharp spade, two garden forks, shears, and a sturdy knife. Sterilize these tools before you start.
2. Choosing Pots: If you’re repotting indoors or gifting, pick sturdy, well-draining pots for each divided plant.
3. Soil: Agapanthus prefers rich, well-draining soil. Mix in organic matter like compost and, if needed, add perlite or coarse sand to improve drainage.
4. Dividing Points: Most people divide the plant into halves, thirds, or quarters, but smaller divisions take longer to bloom.
5. Dividing: Gently dig around the root ball and lift the plant. For potted plants, tip the pot and slide the plant out. Divide the roots by hand, using garden forks if needed for leverage. Be careful not to damage the root system.
6. Check for Damage: After dividing, inspect the roots and trim away any damaged areas. Also, remove any dead or damaged leaves, trimming healthy ones down to a third of their length.
7. Planting: Place each division at the same depth as the mother plant. In the garden, space the divisions 12 to 20 inches apart. Keep them moist for 4 to 5 weeks as they establish. For potted plants, place them in a spot with bright, full sunlight.

With these simple steps, you can keep your Agapanthus plants healthy and multiply them for years of enjoyment!
