Will roundup hurt dormant tubers?
I have a bed of caladiums which are now starting to die off for the winter. The weed infestation is pretty bad, and they have grown all into the mulch I had in the bed. Im thinking that once the caladiums die off the rest of the way, I'll hit the bed with roundup to kill the weeds. I don't think it will hurt the caladium tubers, and they should come back in the spring. Is this true? Or will I kill the tubers? Thanks!
