How To Propagate Agapanthus By Seed

Step 1

Harvest agapanthus seeds in late fall after the seed pods become brown. Keep them in a dry location indoors until the pods split open. Remove the seeds and store in a cool, dry place until early spring.

Step 2

Choose the right location in your home to place the planting containers. Agapanthus seeds germinate more quickly in an area that receives at least six hours of full sun with temperatures that range from 70 to 80 degrees Fahrenheit.

Step 3

Prepare planting containers four to six weeks before the last expected frost in your area. To ensure proper drainage, add a few pea-sized gravel pieces to the bottom of the containers before filling with a good quality potting soil. Make sure that the soil you choose does not have added fertilizer, as soil that is too rich will result in spindly seedlings.

Step 5

Sprinkle agapanthus seeds on top of the soil and add 1/4 inch of the potting mixture on top. Add water slowly, taking care not to push the seeds too deeply into the soil.

Step 6

Water regularly, whenever the top layer of soil begins to look dry.

Step 7

Thin the seedlings if they begin to crowd one another for space.

Step 8

Transplant the new agapanthus into a sunny, well-drained location once they have developed their first set of true leaves. Continue watering the plants regularly to make sure that they develop a healthy root system to see them through their first winter outdoors.
