Agapanthus - in pots or the ground..?

Hi all,

I read a lot that agapanthus like to have their roots constricted and not to over-pot them.

How can this be achieved if they are planted in the ground? I would prefer not to have them in containers as they require so much extra care.

Any advice on this would be gratefully received.

    @learnhow2salsa For many years I grew a deciduous one close to a path. Then I split it into five. Two were further back in the border but flowered just as well. I water and feed them once a week from mid April until a few weeks after flowering. Some  flower better than others. The evergreen ones are not hardy here.

    I think it's at least partly a myth. I have some in the ground and they flower fine (better than the ones in pots, but that might be down to variety - they are different ones).

  • Thank for your responses. That is helpful. It seemed to me that if a plant cannot thrive in the ground, then it's not a 'plant' (!) if you know what I mean.
  • GHardenerSuze - I take your point about hardiness though. : )

    I used to chat with the National Collection Holder of agapanthus and a breeder of over 250 varieties. In his words " Agapanthus are best in the ground "

  • Thank you Hostafan1 - that's really good to know : )

    @learnhow2salsa I grow A. Navy Blue and it had about 30 flowers on the five plants. The best for flowers in my opinion.

    I've about 30 deciduous varieties in the ground and about 20 evergreen varieties ( they are in pots and go into a polytunnel in winter )

  • I'm fairly new to growing agapanthus, but I love them. Good to know that the evergreen ones are less hardy - thank you.

    @learnhow2salsa I guess it may depend on where you are in the country. The evergreen ones are often grown in pots so that they can go in a greenhouse over winter. All of the tall ones in pots will lean away from the wall to the sun.
