Cym browning leaves, hollow bulbs, almost all gone :(

You have rot on these bulbs is shown with the smelly bulbs.
1) check the existing BBs. Remove the old dry leaf sheaths
2) squeeze the roots. If they are soft that means they are dead. If they are on the BBss they will NOT germinate new leads
3). cut half the roots off and slip the velamin off the remaining soft ones. Frankly, I would take almost all the soft roots off leaving only enough to anchor the plant in the new mix.
4) check the cut on the oldest BB where you removed it from the rest of the plant.
5)Does it smell? Is the cut black? If either of these, you will need to remove this BB too as this rot spreads from BB to BB either starting at the newest growth or at the oldest.

You can either pot each up in a small pot or put in plastic bags or try one of each. If the rot is still in the BB's you will eventually lose the plant, however.
