I have grown similar Dracaena that Lin mentioned using water gel beads for about 7 years in a glass container with no drain holes before it started to decline, but I was able to salvage some green parts. Got to love the resilience of this plant as long as it gets some moisture.
But typically I grow my Dracaenas indoors, never outdoors here since it is too hot and dry.
You can try going semi-hydroponics if you want, using clay rocks as media and a plastic container with two drain holes about an inch or so from the bottom, so every time you water, excess water will drain, and still maintain reserve water below the drain hole. Clay rocks will wick water and Dracaena roots will have enough air and moisture at root zone level. But I would keep the plant indoors in an area with some bright light.
