All dracaena plants like to be kept on the dry side. Water well and then allow the top 50% of the soil to dry out before watering again. Never allow the plant to sit in water. The lower the light level the less water a dracaena warnekii needs. All types of dracaenas are very sensitive to fluorine and chlorine. If your household water is heavily chlorinated or contains a great deal of fluoride, allow it to sit out over night before using it; use water from an outside hose; use rain water or distilled water. Never use water that has passed through a water softener. It is too salty and can damage the leaves
