Dumb Cane Care
Common Name: Dumb Cane
Botanical Name: Dieffenbachia Seguine, Dieffenbachia maculata, Dieffenbachia amoena ( see below for available varieties)
Dumb Cane? A lack of intelligence has nothing to do with this vibrant, tropical, and easy-to-care plant. Dieffenbachia will adapt to different environments and require little attention from you. The Dumb Cane refers to the toxicity of its sap -- if ingested, it will burn your mouth, numb your throat, and possibly paralyze the vocal cords, Not a dumb houseplant! If you are able to provide bright, indirect light, you will see your Dumb Cane’s mottling and vibrant markings proliferate. Low light is no concern, however. As this indoor plant matures, its stem thickens and the lower leaves drop, becoming statuesque small trees It also produces flowers, which usually remain hidden beneath the showy foliage. You can remove the blooms to encourage more foliar growth.
Important! Dieffenbachia are poisonous if ingested, so be very careful if you have pets and/or small children.
Most varieties do well in low light, but some Dieffenbachia varieties like a little more indirect sunlight. In either case, the plants will live and thrive, but in lower light the growth might slow down. During the growing season, expose them to more indirect (never direct) light in order to facilitate healthy, new leaves.
Overwatering this or any houseplant should be avoided. Although these plants don’t like to dry out completely, it’s important that they never sit in standing water. Conversely, the plant will also suffer if the soil becomes too dry. The goal is to keep the soil slightly moist without overwatering.
60-85℉ is best for Dumb Cane. If the temperature drops below 50℉, the plant will stop growing.
Dieffenbachia love moisture in the air; more is always better. The goal should be to have a 60 percent humidity level throughout the year. You can place your plants atop a tray filled with water and pebbles, or use a humidifier. Misting the plant’s leaves is a temporary help, but isn’t enough to keep the humidity levels sufficient.
During the growing season, feed the Dieffenbachia half-strength complete liquid fertilizer. Don’t feed them in the winter months. If your Dieffenbachia sits in brighter light, then fertilize more frequently.
