All useful advice, but I might add that to flower well, Agapanthus do like to fit snugly into a pot. You'll need to divide them every 5 years or so as if they become too pot bound, then flowering decreases substantially.

It is also absolutely VITAL to wear gloves when handling the roots of this plant, particularly with the roots. The sap of the Agapanthus is toxic and can cause severe stomach cramps. Gloves should be worn at all times when handling earth/commercial garden compost, even if you have had a Tetanus injection.

My agapanthus has outgrown its pot and it is very big had 16 blooms this year, how do I split it up and when ?

Just bumping this up Brian as no one has replied yet. 

I'm not an expert on Agapanthus but I'd think you could split them now while the weather's still favourable - just take out the pot and split with a knife (or spade if it's a big one)  and re pot the pieces. Keep them out of harm's way till they're settled. If I'm totally wrong about that I'm sure someone else here will help.

If my Agapanthus get to big and I don't want to change my pot can I split them?

Hi Patricia,

I split mine in Spring, just before they come into growth .

Mine didn't read the rule book which says they won't flower the year they're split and virtually all have flowered.

I have to say, I've never worn gloves and I've been handling compost for over 40 years , and for over 25 years ran my own gardening business. I only wear gloves if something is particularly thorny.

I bought another 3 agapanthus recently from Pine Cottage Plants  who hold the National Collection of Agapanthus and they say  in their leaflet

" Whilst the very best plants are produced by growing them in the ground, excellent results and flowering can be achieved by cultivation in containers."
