When spring comes, the plant will start growing anew.

The plant has very basic requirements and is particularly fussy about sunlight. However, apart from that, it will guarantee to bloom through the entire summer.

As spring starts, and till the plant flowers, feed it a weak liquid fertilizer. Do not feed it while flowering and stop completely in winter. Its blooms are more vibrant if they are under slight stress.


The agapanthus family spreads through rhizomes, so it can become invasive. However, the African lily has not been permanently categorized as invasive in any region till now. Just dig out the plant with its roots if you think it is becoming invasive.
