“Warneckii” dracaena (Dracaena deremensis “Warneckii”) is a green dracaena cultivar with white stripes along the edges of its leaves. It is a shorter dracaena that matures to a height of only 4 feet tall. While its low light requirements make it easy to grow indoors, it can also be grown in shady sites outdoors in U.S. Department of Agriculture plant hardiness zones 10b and 11. Other cultural requirements for “Warneckii” are also fairly easy to meet. When these requirements are not met, or if it is exposed to a common chemical, the leaves tend to develop unsightly brown tips.
Overwatering, underwatering and dry conditions can cause brown tips on “Warneckii” leaves. It should generally be watered once per week but this varies, depending on the season and humidity levels. In dry homes or dry outdoor conditions in spring, summer and fall, “Warneckii” dracaena may need to be watered more often. Give it a thorough drenching with water that is the same temperature as the air when the soil is dry at a depth of 1/2 inch. Water the plant in the morning. A “Warneckii” dracaena grown in a container should be watered until the water drains from the bottom.
