Hi Kim,

A dracaena, and from the first picture I think it is the lemon lime variety, is a “stalk” plant. As these plants mature, they will lose their bottom leaves. This process is normal as long as they are getting new leaves at the top of the plant. If you don’t like the bare stalk, you can buy a small dracaena (or a couple of them) in a 4″ or 6″ pot; take it out of its pot, and plant it near the base of your existing plant. As the new plant grows it will cover the bare stem. You can read all about a dracaena lemon lime (or if the leaves are a more solid green, a dracaena janet craig) in the Popular Houseplant section of the website.
