Agapanthus is an African lily that many people choose to grow for its blue, purple, white and pink blooms. Originating from South Africa it is herbaceous and will grow well in containers or direct in the ground, as long as it gets a lot of sun and the drainage is good. To keep them looking their best and growing well you need to put in a bit of effort when it comes to autumn. Deadheading is a yearly task for all gardeners who keep a variety of flowers. Here’s how you should go about deadheading your agapanthus.


Keep an eye on your agapanthus and deadhead the flowers after they bloom in the summer when the heads of the flowers will start to dry. Unless you want to harvest seeds from them you should take the heads off as soon as this starts.

Using secateurs, trim the heads off at the stalk, down to where the dryness stops. Alternatively, simply use your finger and thumb to snap them off. If you have left them for a long time and seeds have formed, cup your hand under the flower to collect the seeds and prevent any unwanted growth.

Return to the plant after the first deadheading blitz if there were remaining flowers that had yet to die off. Be sure to take all the heads off because the plant can then put all its effort into new growth rather than the formation of seeds.
