Are my pine trees dying?

Asked November 6, 2018, 11:08 AM EST

I have several pine trees on my property, white pines I think. one of them went completely brown this summer and looks dead. all the other ones, about 10, have yellow / brown patches (within the last few weeks) and not just on the inside as many online info says pines loose some needles in the fall. I have posted a picture of the "dead" one and one next to it with patches. any advise would be appreciated. Thanks, .

Once a tree is dead it is difficult to diagnose why. As soon as you notice symptoms, please send us photos so we can see what you are dealing with.

When subject to poor site conditions, drought, poor drainage, root issues, etc. the trees can be susceptible to insect and disease issues but these are secondary problems. If pines are planted in a row, there is a lot of root competition for moisture and nutrients, and in shady conditions they grow slowly and lose their lower branches. See our publications on pines for more information
and information on How to Decide When To Remove a Tree

The pine on the right shows normal needle drop. See see more information
