Dragon trees grow best in bright light but they can also survive in dim light. Plants in lower light situations will grow slower and will produce smaller leaves with less intense color. Don't put your dragon tree in full sun, which can burn its leaves.
Dracaena plants have a relatively low need for fertilizer. Feed them lightly at the beginning of spring or twice a year with controlled-release fertilizer. Do not fertilize in the winter.
Repot your dragon tree into larger pots as necessary. Since these trees grow so slowly, they generally require repotting only every second or even third year. Refresh potting soil annually with fresh soil to replace any that has become compacted.
