Hi there

I wonder if anyone could recommend what type of compost to use for potted agapanthus.  I have some  grown from seed in multi purpose for three years which although healthy have not flowered .  Am I being impatient or should I repot in spring in John Innes?  Any help appreciated. ps they were fed during spring/summer.

    I think I used JI no3 with some grit added as they like good drainage. Having said that, mine didn't flower last year (their fist year) either. 

    Some say they like to be pot bound to flower well, others say its a myth, I'm not yet enough of an expert to say either way I'm afraid.

    I stick a layer of gravel underneath and then just whatever MPC is on special offer.

    I'm in the "it's a myth" camp re potbound plants. If they had to be potbound to flower, why do they flower when planted in the ground?

    Tomato feed in Summer and never let them dry out completely in late Summer / Autumn when they're forming the new buds for next year, as this is a common cause of lack , or loss, of flowering.

    They do take at least 3 years to flower from seed... I had loads in the border in my last house which bloomed every year - They weren't pot bound. They do like good drainage though. Hope they flower this year for you and as said above a Tomato feed and make sure they don't dry out. Good luck. image

    Thanks very much.  Not allowing them to dry out may well be the reason as I did keep them on the dry side.   I am hoping my patience will pay off this year  with lots of blooms and wondering if they will come true to the parent plants.

    Cate, don't give up on them. If, as you said, you kept them on the dry side, you might already have damaged the chances of good flowering this year. Keep them watered and fed this season and you're bound to get flowers next.

    Thank you I am going to persevere and give them a good talking to????

    I have them planted in the ground, not pot bound and flower every year but it took 3 years to get flowers on mine.

    My 5 year old pot of them never flowered. I told them last year was their last chance and threw some tomato feed at them.  Bingo - they flowered!  I think it is just patience!
