Cinnamon is an evergreen tree characterized by oval-shaped
leaves, thick bark, and a berry fruit. When harvesting the spice, the bark and
leaves are the primary parts of the plant used. Cinnamon
is cultivated by growing the tree for two years, then coppicing it,
i.e., cutting the stems at ground level. The following year, about a dozen new
shoots form from the roots, replacing those that were cut. A number of pests
such as Colletotrichum gloeosporioides, Diplodia spp.,
and Phytophthora cinnamomi(stripe
canker) can affect the growing plants
The stems must be processed
immediately after harvesting while the inner bark is still wet. The cut stems
are processed by scraping off the outer bark, then beating the branch evenly
with a hammer to loosen the inner bark, which is then pried off in long rolls.
Only 0.5 mm (0.02 in) of the inner bark is used the outer,
woody portion is discarded, leaving metre-long cinnamon strips that curl into
rolls ("quills") on drying. The processed bark dries completely in
four to six hours, provided it is in a well-ventilated and relatively warm
environment. Once dry, the bark is cut into 5- to 10-cm (2- to 4-in) lengths
for sale. A less than ideal drying environment encourages the proliferation of
pests in the bark, which may then require treatment by fumigation. Fumigated
bark is not considered to be of the same premium quality as untreated bark
