Each year, evergreens have a seasonal needle drop that’s a regular part of its cycle. Evergreen possesses various lifespans and don’t stay attached to a tree for life. As they mature, many evergreen needles turn yellow, next brown, and drop off.
The change can be slow or as with some species, very quick. Seasonal needle drop can be of massive concern to homeowners who don’t know about this natural occurrence. In times of drought, needles turning brown can be quite noticeable since most needles shed in response to stress.
Their yearly loss of needles can be particularly alarming on older white pines, as the number of yellow needles is more than the present season’s green growth. Usually, white pines will keep their needles for a few years. However, in the fall, young needles change color and drop, leaving only the present season’s growth still joined.
Some pines (Scots and Austrian) typically keep their needles for a couple of years. Fir and spruce needles will turn yellow and drop. Though, the change generally is less noticeable since their mature needles are increasingly thinned, making the procedure slower than in pines.
When it comes to evergreens and seasonal needle drop, it’s best to assess your tree regularly. Contact an arborist in Syracuse if you would rather have a professional tree assessment.
If the growth in the present season is wilted or discolored, the tree could be the victim of a severe insect or disease problem and must be identified to determine if control is warranted.
Sign of Trouble in Yellow Needles?
Yellow needles in the earlier part of the season and the yellowing of new growth are different tales. If this occurs, examine for other causes like spider mites, drought, or insect. Also, look for symptoms on the bark, roots, and needles that can create dryness.
If you see an indication of yellowing in isolated parts of a tree or if it begins in a remote spot and begins to expand slowly, you should collect some branches and needles. Take them to a tree care company and have them inspected for pests or disease.
