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.
