We
are starting to see very noticeable natural needle drop on some
pines. This is a process where 2- to 4-year-old interior needles
turn yellow, then brown, and eventually drop off. Those who aren't
familiar with this process often are concerned about the health of the
tree. This is a natural phenomenon that occurs every year and does
not hurt the tree. However, some years it is much more noticeable
than others. Be sure to check that only the older needles are
affected - the needles on the tips of the branches should look fine - and
that there is no spotting or banding on the needles that are turning
yellow. If spotting or banding is noted, take a sample into your
local county extension office for diagnosis.
