Dieffenbachia (deef-in-BOCK-ee-uh) are popular house plants because of their attractive foliage and their adaptability to interior environments. They are medium sized plants, usually growing 3’ to 5’. Hybridizers have produced many beautiful new Dieffenbachia hybrids that can add color and interest to your interior décor.
Dieffenbachias are sometimes called “Dumb Cane”. This common name refers to the presence of calcium oxalate crystals which, if chewed, can cause swelling of the throat and tongue. A severe reaction can result in asphyxiation if the airway closes. Keep plants away from small children or pets that may ingest the toxic leaves. The sap can give some people a rash.
Moderate to bright indirect light.
Moderately dry between thorough waterings, do not allow roots to stand in water.
Warm temperatures of 65°F or better.
Average house humidity is fine.
Apply a general purpose house plant formula when plant is actively growing. Over-fertilizing can cause leaf-tip burn.
If plant becomes leggy, cut the canes back to a point just above an old leaf joint. New growth will appear along the trunks or around the base of the plant. Cuttings can be rooted in water or in a light potting mix.
