I have a dieffenbachia plant that stands about 6 feet tall (one stalk). It is bigger and healthier at the top than the bottom. The leaves are bigger and closer together. It is top heavy and I have it tied to a stake. I wish it were shorter. I have read that you can start a new plant by planting a portion of stalk, keeping it watered and new roots will grow. My question is: Can I cut the top half of this plant and plant it the same way? Will it grow roots and live?
