I planted an onion patch and it became infected by a disease and died. I tried using a plant cure but the response was "This patch doesn't need curing" Help!!!

you have to cure before it dies i'm afraid. it's gone now, try again

Any suggestions on how to get rid of the dead onions? I tried digging and raking so far.

 

 

 

Thanks

digging should do it, unless im much mistaken (use a spade)

You have to 'use' the spade with the dead onions.
