Help my cordyline red star !!?

Question

I have a few cordyline red stars that I planted in August 2006. I have one die and two more are looking a bit sad.
The leaves look like they are being eaten. I was told that slugs attack them. Could this be true. I put slug bait out but they have got worse. Do they like wet feet or dry feet?
What can I do to revive them?
Thanks

i also found this:

These plants are generally untroubled by pests and diseases. Leaf spot can be a problem and where it occurs affected leaves should be removed promptly to curb its spread. Scale insect and red spider mite are sometimes troublesome under glass.
