Getting your planting technique right is a total game-changer in the garden. If you get your Lily of the Nile (Agapanthus) in the ground at the right time and give it the TLC it craves, it’ll reward you with those stunning, iconic flower clusters. Here’s everything you need to know to get started.

When to Plant Your Lily of the Nile

The best time to get your Lily of the Nile—also known as Agapanthus—into the garden is during the spring. Wait for a dry day once the threat of frost has passed; usually, March or April is the sweet spot. You can start fresh with new bulbs or propagate your own by dividing the tubers from a plant you already have in a pot or garden bed.

If you’re planning on dividing your plants, keep these tips in mind:

  • Be patient! Divided plants sometimes take a year off from blooming to settle in.
  • Use a sharp spade to carefully separate a section of the tubers.
  • Don’t skimp on size—make sure each new clump is substantial enough to thrive on its own.

Choosing the Perfect Spot

While Agapanthus can handle a bit of partial shade, these beauties are true sun-worshippers and really thrive in a sunny location. The biggest “no-no” for these plants is “wet feet.” They absolutely hate standing water, which can lead to root rot. If your garden soil stays a bit too damp, try adding a drainage layer to help things out. If you’re planting in containers, mix some sand into the bottom of the pot to ensure water flows through freely, especially during those heavy summer rainstorms.

Pro Tips for Agapanthus Care

Once your Lily of the Nile starts blooming, it’s going to be thirsty, so make sure to water it regularly. They also appreciate a little extra “food” during the growing season. From May through early September, hit them with the right fertilizer about once a month. This extra boost supports healthy growth and ensures you get those massive, beautiful blooms all summer long.
