How to Care for Agapanthus After Blooming

Written by sara tetreault | 13/05/2017

Agapanthus flowers grow on a long, thin stem in bunches. They are known for their bright blue/purple flowers and are also referred to as lily of the Niles, African blue lily, or just plain African lily. Once an agapanthus blooms, this is an ideal time to begin splitting the clumps of blooms into separate plants so that you can separate them into different areas of your garden or yard.

Continue to regularly water your agapanthus as you would during any other time. You will want to make sure that you water deeply so that you can help the plants to develop extensive root systems. You should water the plants when the top three inches of soil has become dry.

Divide clumps of the agapanthus, according to the size that you would like to plant in another area of your garden, by using a sharp knife to cut through the root system. Be gentle with the divisions and replant them within a few days of dividing the plants.

Deadhead the blooms that have died in order to encourage new growth on that particular stem.

Fertilise the plant every two weeks with a water-soluble fertiliser. The best time to do this is while you are watering the plants. Be sure to follow the directions on the fertiliser container for how much fertiliser to use as each brand and type vary.
