Southern blight question
I've been gardening in this location for 12 years, and have never seen southern blight here. I just noticed it on a new hosta (planted 3 weeks ago). I know it lives in the soil, so does that means it's always been here, and I've just been lucky to not have noticed it before? Since the hosta arrived bareroot with no soil attached, i'm assuming it did not hitch a ride with the hosta. I've already trashed the hosta, but just wanted more info on how southern blight has managed to escape me for so long. OTOH, it has been the driest and hottest summer ever. I'm zone 5 Chicagoland.
