Diffenbachia

Several varieties of this popular houseplant are available. One of the thougest is Dieffenbachia amoena, with big, bold, dramatic leaves. If you’re short on space, try the small-leafed varieties such as Rudolph Roehrs (D. picta), which features chartreuse leaves with green midrib.

Light
Dieffenbachia tolerates a wide range of light-from poor to bright. Full sun, however, will yellow the handsome foliage. So give in north, east, or west light-but no more than two hours of direct sun a day.

Water
Don’t let the soil dry out completely or the edges of the leaves will become discolored. If the leaves start too drop, you know that water is needed. One way to water thoroughly is to immerse the pot (not the plant itself) in a pail of water. When the water stops bubbling, the soil is saturated. Remove the pot and allow the excess water to drain out of the bottom of the container. If your house is dry, move your dieffenbachia into a steamy bathroom occasionally.

Special Helps
This native of the tropics likes 70 to 80 F temperatures. Use standard potting mixture. Fertilize with regular houseplant food in spring and summer.
As plant matures, lower leaves die, leaving a leggy stem that’s unsightly. Cut off the plant several inches above ground level and root the stem in water. After roots form, you can pot up the plant or continue to grow in water. The original potted plant will sprout a new stem on the stub
