Should I divide my Agapanthus?

Hi. This is my first post and probably one that's been answered before. 
I have Agapanthus in 2 different pots and last year they didn't do much. Previous years I've had at least a dozen flowers in each pot. As you can probably tell from the pictures, I have a lot of grass and weeds growing in the pots too. What would be my best plan of action here? Take them out and remove all the grass and weeds from the top layer and repot them with fresh compost? Or, divide them and keep a large cluster in the pot and a plant a few smaller ones in the ground?
I'd appreciate any help you wise gardeners have to offer. Many thanks.

    It is said that agapanthus like to be cramped, but that looks to me like a lot of plants. I have a pot of similar size and I have only 6 bare root plants in there. 
    But whatever you decide, they definitely will benefit from having the soil cleared of grass/weeds and the compost topped up with fresh stuff.

    I moved house early this year and I took my agapanthus in a pot with me, very similar to yours. I don't want masses of pots anymore so I bit the bullet and divided it into 5 plants which I've planted in the new flower borders where they are growing well. But I can't tell you whether they will have flowers yet! It was tough dividing them, I used a pruning saw.

    I had two agapanthus of the "Star" varieties in beds at my last house and they flowered.

    From Spring to Autumn, water your Agapanthus regularly, and give them a liquid plant food weekly (something like Tomorite).  That will encourage them to reliably flower every year.

    Adding to Keen’s wise words, watering and fertilising is especially important from flowering until the leaves start to turn yellow. This is when next season’s flower buds are forming.

    Thank you for all your input. I think I'll see how they look when I pull them from the pots. I would like a few in the beds. I've seen how difficult it can be to divide and even remove from the pots on YouTube videos.  Either way I'll definitely remove the weeds etc and give them a good feed.

    If you put them in open ground, add lots and lots of grit or sharp sand. 50% soil and 50% grit will serve agapanthus well.

    I planted about 40 different , deciduous agapanthus in my new bed( heavy, rain soaked Devon )  last year. I just left the crown slightly proud of the soil level and they all thrived and flowered well. Most are showing signs of new growth already. 
    IMHO agapanthus are subject to much myth.
