Getting agapanthus to flower
Hello experienced gardeners, I have just been given three agapanthus plants as shown in the photos. It was a real struggle to get them out of their pots but the previous owner wanted her pots back just not the plants! The lady no longer wanted them as she said they'd never flowered for her in the three years she's had them (she had them in the pots in full sun). She was going to bin them!! I couldn't resist rescuing them instead. So, my question is, what would you advise me to do? I had planned to repot them each in a new pot (not much bigger than they were in before because I know they like to be crammed in but at least they'd have a bit of fresh compost) then to give them some tomorite (?) and then to put them in full sun. But if anyone thinks I'm missing something vital to get them to flower please let me know. Sorry about the messiness of the pics, they were heavy and I just dumped them on the table as I'd just got home from work. Thanks everyone.
I wouldn't split them now, if you want them to flower this year, as that tends to delay flowering. I start feeding mind as soon as I see new shoots coming up (with Tomorite), and I don't stop until well after flowering.
Regular watering and feeding, plus full sun, is what usually results in reliable flowering. There is a myth that they thrive on neglect, and many people don't do this, which may be why they didn't flower for the previous owner.
Given the leaf, I'd suggest they're evergreen varieties which are not as hardy as deciduous types. They'll need a bit of shelter over the winter.
KeenonGreen, there are two crowns in each pot but I won't separate them this year as you say. I want to try to get them to flower first and them think about separation. I might put one clump in the ground to compare..?
And yes Hostafan1 I think they're the evergreen type, the leaves are very wide and I don't remember them dying back. I have a conservatory so I can bring the ones that go back into pots inside over winter.
Fingers crossed for a brilliant show this year... Many thanks again everyone.
Never grown Agapanthuus before. I have seen them in gardens and love the blooms so thought I would give them a try. Where they are planted, they will get won from late morning through to evening.
