Here is what the gingers are doing. It is affecting all kinds except the shell and variegated shell gingers in the ground. The ones I still have in pots haven't died, so I'm thinking it's something in the soil. When I dig them up, it's like the roots are rotting. They are not in constantly wet soil, some are in shade, some in more sun, doesn't seem to matter.
I dug a bunch this morning and the ones that still have green sprouts on, I"m going to plant in a shade bed with amended soil and use a Subdue Maxx drench.
