The lower leaves on my western columbine (Aquilegia formosa) have been yellowing, withering, and browning pretty consistently since I got it. I’ve just been plucking the ones that look super bad and watering normally for the species but it actually seems to be getting worse so I think something is wrong? At first I thought maybe sunburn or something but the only leaves that are affected are the lower ones so I’m starting to suspect something fungal or bacterial? The rest of the plant actually seems super healthy so idk what’s going on.
