yellowing leaves on potted agapanthus
A friend gave me a nice clump of agapanthus last spring, which I put into a medium size pot and left outside for the summer months. It grew tremendously, putting out a lot of roots which seemed to gravitate to the surface. I repotted it up a size when bringing it indoors. It seems pretty happy in a southeast facing window, but I keep having to remove leaves that are yellowing. I haven't fertilized it--well, maybe once or twice. Are occasional yellowing leaves a normal thing? Also, I'm keeping it on the dry side to try to induce blooming in the late winter. All suggestions welcome.
