Indigofera is sick!
Help me! I redid all of my flowerbeds this spring and everything is nice and healthy except the indigoferas. I do not know what subspecies (it seems there are a couple) but it gets flowers that are pink with a tinge of purple.
Everything around them is healthy. The best thing I can think of is they are not draining well enough, as there is lots of clay in the soil. I am not sure of this though because there are dwarf bottlebrushes right next to the indigo (which have similar water requirements) that are doing great. I did stick my finger in the dirt a couple of days after watering and it was still damp.
So, what do I do at this point? I am tempted to pull them up and put some better draining soil around and replant them, but I don't want to shock them anymore than they are already. Suggestions anyone?
