Each plant is unique. Size, shape, fullness, and variegation will vary.
Every home has one—a dark corner or an empty shelf that’s crying out for some decorative greenery. Dieffenbachia (dumb cane) plants are the perfect solution for creating an immediate impact in those barren spaces. Flaunting large, lush green leaves painted with brush strokes of creamy yellow, white, or gold, these exotic-looking aroids beg to be noticed.
Dieffenbachia plants are great for improving indoor air quality because the large leaves are highly efficient at filtering out pollutants. However, be aware that this beautiful houseplant can be toxic for people and pets alike. With proper precautions, you'll be able to enjoy all the ornamental attributes this plant has to offer.
Light:
Dieffenbachia tolerates a wide range of light conditions, but grows best in bright, indirect light, such as from an east- or west-facing window. Most plants will also do fine in darker areas of the home, but they won’t grow as vigorously and may become spindly. Avoid direct sunlight, which can scorch the leaves and cause the colors to fade.
TIP: To ensure even growth, rotate your dieffenbachia regularly so it receives light from all sides. Otherwise, it tends to lean towards the light source.
Temperature:
Prefers average room temperatures of 65° to 75° F. Keep away from cold drafts and temperatures below 55° F.
Humidity:
Like most tropical houseplants, dieffenbachias prefer moderate to high humidity. In drier areas of the home, you can keep your plants hydrated by misting the leaves, setting them on a tray filled with pebbles and water, or grouping your dieffenbachia with other houseplants.
Soil:
Use a well-draining potting mix that has good moisture retention.
Watering:
Water regularly spring through fall, allowing the soil to dry to a depth of 1 inch between watering. Water less often during the winter. To avoid soggy soil, which can lead to root rot, make sure there are sufficient drainage holes in the bottom of the pot so your plant will drain completely after watering.
Fertilizing:
In March through September, fertilize every two weeks using a liquid houseplant fertilizer diluted by half. Feed less often if your plant is growing in low light. Stop fertilizing in winter.
Pruning and shaping:
As dumb canes mature, lower leaves naturally drop off to reveal thick stems, resulting in a palm-tree-like appearance. If you want a bushier plant, simply cut the canes back to the desired height and new growth will emerge below the cut. It’s best to cut the canes at a 45-degree angle just above a leaf node, making sure not to remove more than a third of the plant’s foliage.
CAUTION: Always wear gloves when pruning a dumb cane to avoid skin contact with the plant sap. Also avoid touching your face and eyes.
