Though there is not much known about this
application, we believe this represents a real opportunity for
the cut foliage/flower producer. Caladiums come in a wide
array of colors, leaf shapes and leaf sizes. Because of
little information, we cannot make any specific recommendations
for this application and only suggest the innovative cut
foliage/flower grower experiment with various varieties using
different leaf maturities. Because of their ethylene
sensitivity, something like Silver Thiosulfate should be
considered in the holding water solution. DO NOT PUT CALADIUMS IN A COOLER AT TEMPERATURES
LOWER THAN 65°F (19°C).
They are
quite happy at room temperatures (75°-78°F: 23°-25°C)
We have found that the petiole or stem can be weak and cause
problems with the shelf life of cut caladium leaves. This
has been overcome by sliding the entire stem into a plastic soda
straw. Utilizing this method we have found leaves will
last three to four weeks in tap water (though deionized water
may work better). Cut leaves just above where the stem
begins cupping just above the soil line. Smaller leaves
tend to work better in a mixed arrangement than large ones.
De-eying the bulb before planting can enhance the number of
smaller leaves. Do not cut
leaves before they are fully opened.
Recently matured leaves work best
