My Zebra Plant has grown very tall but is not lush is there any way I can get more leaves to grow?
You can cut the plant down and propagate the cutting.
Propagation: Take 3-inch (7.5 cm) stem tip cuttings in spring or summer. Cut the stem just below a node -- the place where a leaf is attached to the main stem. Dip cut ends in rooting hormone powder then insert them in seed starting mix or perlite. Enclose the potted cuttings in clear plastic or use a glass cloche to hold in humidity. Set the covered cuttings where they'll get indirect light. Water when the potting medium appears to dry out. After 3 weeks, you can remove the covering. Gradually expose the cuttings to more light. You should see new growth in about 6 weeks.
There is no way to grow new leaves at the base of the plant.
