Q.wintering over tuberous begonias
My tuberous begonias (20 specimens) developed powdery mildew at the end of the summer. I kept it under control…to a degree organically, but in the end, my treatments never really got rid of it. My question is…is it worth it to winter over all of these tubers? Or will they just be plagued with the powdery mildew next summer?
It should be all right to store and replant your tubers, as long as you thoroughly get rid of all the diseased foliage above the ground.
