My pencil plant is about 6 feet high. The only foliage is the top 12 inches with one bottom branch. The upper branches have small leaves that have died and only the leaves on bottom branch have survived. Will new leaves appear or is the plant dying?
The pencil cactus leaves are very small, and only last a short time. In other words, the plant isn't really supposed to have leaves at all, except for a short time in the spring, or whenever its growing period is.
