Looks like a root problem

[TOMD]

Hi all, Just received this Bl. Morning Glory today from Aloah. The plant looks ok execpt for the roots.It was nearly out of the pot.and looking closer at the roots you might not be able to see in the pic but i can see a few rotted roots. my question is should i wait till it blooms or would it be ok to repot now. hate to loose the buds.Pic 1is the whole plant,the second is the buds. and the third is the roots. would appreciate you advice. Thanks so much TomD
