    Dieffenbachia Tropic Snow is a very attractive large houseplant, it's easy to grow as it tolerates poor lighting conditions and neglect. Under the right conditions it will bloom most years. I like 3 canes per pot for a nice full look. Every few years the canes will need to be cut back to rejuvenate the plant as it becomes too tall and top heavy. I cut the top of the plants off leaving about 12 inches of cane, remove some of the leaves, dip in rooting hormone, place in a container of water until the roots are a few inches long and then plant in a new pot with fresh planting mix. Cut the remaining canes in the pot back to 2 or 3 inches and new plants will sprout from the canes or the soil, as a bonus you will have an extra plant to keep or give away. I was given the original plant about 15 years ago and have since given away many plants to family and friends.
