Spruce trees are getting a lot of attention this fall. Their inner needles are turning yellow or brown and dropping off.
To put your mind at ease, it’s not unusual for these conifers to shed interior needles beginning in late summer and continuing well into fall. This is normal evergreen behavior.
In fact, all conifers (“evergreens”) including spruce, pine, fir, juniper and arborvitae lose their oldest needles every year. Contrary to what the name implies, “evergreens” are not really green forever. Their needles generally have a 2–4 year life span, although spruce tree needles live about 5-7 years.
