Some varieties, especially Dracaena marginata , are prized more for the form of the trunks than the foliage. Make sure they are well rooted. They are tolerant of low light but will do their best with bright, indirect light. Avoid direct sun in the afternoon. Plants grown in low light grow very slowly.
Dracaenas do well with a weekly soaking.
Do not allow them to stand with water in the saucer for more than an hour or two. They may need a little more water in the warmer months. Avoid allowing dracaenas to dry out completely. They tolerate a wide range of temperatures and do well in almost any indoor environment. If it is especially warm, be sure to provide extra water.
