3 Spruce trees #733718

Asked November 11, 2020, 10:04 AM EST

The last couple of wind storms have brought down an unprecedented amount of brown needles.
Is this a cry for help?  Is there anything I can do to help these huge old trees?
Are needles a good mulch or is store bought bark mulch better?
thank you

It is normal for evergreens to shed some needles ever fall, but also between the dry winter of 2019-2020, the April freeze, and one of the hottest summers on record (and driest), trees, especially evergreens, are having a tough time.

Without evidence of an insect or disease, the trees may be suffering from drought stress or lack of winter water, although it is hard to tell from a description. Trees and shrubs in this area need more water than the sprinklers can provide. Here is a fact sheet on care of mature trees:https://cmg.extension.colostate.edu/Gardennotes/657.pdf . Do they receive water year round even during the fall and winter? Extension has a great Fact Sheet on Winter Watering: http://extension.colostate.edu/topic-areas/yard-garden/fall-and-winter-watering-7-211/


Since I cannot see what is going on with the tree, we recommend contacting a certified arborist to come out and take a look.
