We’ve lived in our house for 5 years now and I still don’t know what type of trees are in my front yard (aside from calling them the generic conifer or pine tree).
I can’t get a good look at the bark, but they look like Fir to me, possibly Spruce. If you could show a close up of the bark that would help. Then we can work on identifying which species. They’re not pine trees.
Looking through this guide to common trees of PA (are you in Homer City?) I thought the Eastern Hemlock was probably a good guess. I can’t tell if these trees have tiny cones or big cones, but none of the other ones native to PA looked nearly as close a match as this one. As a bonus, it turns out to be your state tree!
It’s a spruce. I would deduce a diseased blue spruce, from the characteristic needle drop common to the species. A Black Spruce is resistant to the disease and large ones look full from top to bottom. I don’t think it’s White Spruce because of the needle length and color. A Blue Spruce can range from a light blue to a bright green in hue. The variation occurs because they all are seedlings and the variance won’t show until the trees are many years old. Growers don’t want to throw out the majority of the plants at that stage and charge a premium price for the bluest. I think if grows only alowed for the crossing of the best blues they could get a better percentage of blue. The trees may be some other variety of spruce, but I’ll go with it being a Blue Spruce.
Looks like a Spruce to me too.
Roll a single needle around between your fingertips. You should be able to feel the edges. (Almost square in cross-section.) If you can’t roll it because it is oblong in cross-section, then it’s likely a Hemlock.
I am far from an expert, but the trees in the OP’s pix sure look different from what I generally think of as a blue spruce. http://www.friendsofsaguaro.org/spruce-blue.html
Not just the color, but the habit is quite different - less full.
You might want to put some security on that link – I wouldn’t want to allow unfettered access to some of those files. Particularly the one with directions to your house, your names, address, and phone number.
The trees look like Douglas Fir to me, but are more likely Eastern Hemlock given your location.
Hemlock have very small cones, so I don’t think it’s what you have. I think you have Picea abies, the Norway Spruce – same as I have in my yard, in fact. Good photo here, looking very much like your trees.
I can see the severe needle loss againt the background in one picture, and that indicats a common malidy of spruce in the US. The aspect of a blue spruce when diseased is this unfurtunate form. I see many blue spruce like that in Wisconsin since the 80’s. The trees were a solid filled in tree with no gaps, now the ones that don’t die look like the pictures. I can’t say it isn’t a different spruce, but it looks like the sick ones I see around here, including the one in my yard. The new soft needle growth on the tree shows that it is a spruce no matter what variety. I had thought after posting of a type I didn’t mention, that of a Norway Spruce and I will agree that it may be a Norway Spruce.
They are, IMO Douglas fir. Spruce have smoother bark. The needles of the two are similar.
They look ratty, because they aren’t native to your area. It’s pretty obvious, they were planted back in the day.
