Dieffenbachia, generous but to be handled with care

Dieffenbachia is an aroid native to tropical America, grown since the 19th century for its large variegated leaves. It grows fast and tall, on a stem as thick as a cane. Its sap contains highly irritating calcium oxalate crystals: if chewed, it makes the mouth and throat swell, hence its old English nickname, ‘dumb cane’. A superb plant, then, but one to keep out of reach of children and pets, and to prune wearing gloves.

Caring for them in Morocco

  • Light: bright without direct sun; it tolerates medium light but then loses some of its variegation.
  • Watering: when the top of the soil is dry; less in winter.
  • Pruning: when it gets too tall and bare at the bottom, cut the stem in spring, wearing gloves: it regrows below the cut, and the cut piece can be propagated.
  • Potting mix: our Signature Potting Mix, lightened with a little perlite.

Reading the symptoms

  • Lower leaves yellowing and dropping: normal with age, or overwatering if several go at once.
  • Long, bare stem: lack of light: prune it and move it closer to the window.
  • Brown edges: dry air or a cold draught.

Frequently asked questions

Is Dieffenbachia dangerous?

Its sap is very irritating to the mouth, throat and skin. Keep it out of reach of children and pets, and wear gloves to prune it. Touching the leaves without damaging them is no problem.

How is it different from Aglaonema?

Both are variegated aroids. Dieffenbachia grows taller and faster, on a thick stem; Aglaonema stays compact and copes better with shade.
