The Agapanthus, or Lily of the Nile, is known for its clusters of purple, funnel-shaped flowers that bloom once a year, generally between late spring and early autumn. The blooms of this perennial only last a week or two, at the most, but the long, slender leaves remain green and full year-round, which is why Agapanthus is a popular landscaping flower. Agapanthus require a minimum of care, which begins at the end of each blooming cycle.
Snip flowers off at the bottom of the stalk as soon as they begin to wilt. Leaving dead flowers saps nutrients the plant could use to increase the density of its foliage.
Clear the plant of dead leaves and other debris once the flower stalks have all been removed.
Divide the underground rhizomes and root clumps with a knife and replant. Place the separated rhizomes under 1 inch of soil and 18 inches to 2 feet apart.
Water regularly, enough to keep the soil moist but not saturated, until the plant begins developing new growth -- a sign of a healthy root structure. Keep the plant well watered until the next flowering cycle.
