If you notice some yellowing needles on your cedars, pines, arborvitae, spruce and other evergreen conifers this time of year, do not be alarmed. This yearly needle drop typically occurs in fall (sometimes earlier) and is a normal part of the lifecycle of the plant.
The truth is all evergreen conifers shed their older growth, though some (pines and cedars in particular) may do so in more dramatic fashion than others. As long as the yellowing is happening on the interior of the plant and not at the tips of the branches, then all is as it should be.
However, if your conifer is discolored on branch tips or in a specific part of the plant, please speak to one of our plant experts about possible causes and treatments.
