Residential Mature Pine Tree (Mahtomedi)
Hello, I could use some help please... I have a mature pine tree that is not doing too well. It appears to be thinning a lot over the last three years and so far this early winter, more needles appear to be turning brown than usual. I do not know what specific kind it is, but here as some details: -about 30-35 fee tall -main branches are symmetrical and spaced out about 2 feet apart (upwards) at each level -there are no branches the first lower 8-9 feet (so no branches are touching the ground) -I would say about 35 % of the needles look have turned brown (just in the last 4-6 weeks) -branches seem healthy and strong and keeping their shape -thinning has occurred in the last three years (I read someplace that this might be normal before is starts growing healthy again -I purchased this home 10 years ago and healthy up until about there years ago as mentioned above -some new needle buds in Spring 2018 that I thought would change things, but the tree continues to look thin all the way around, and as mentioned now the needles are turning brown on top of the thinning. -tree never has produces solid pine cones, per se..just very small, soft, and brown looking pine cone type cones Trying to provide as much info as I think will be helpful. Can someone there help me out please. Really would like to keep the tree and welcome doing something for it right away. Thanks very much, Charles & Paige Garcia 600 Warner Ave. South Mahtomedi, MN 55115

There are several common problems that could be affecting your tree. Probably a fungal disease and/or insect damage. Some closer inspection of the tree trunk, branches and individual needles may help you determine what is going on. I am not able to see that level of detail from the photos. In the 2 links below, there are descriptions and pictures of some common problems. Compare and see what is consistent with what you are seeing with your tree. https://apps.extension.umn.edu/garden/diagnose/plant/evergreen/spruce/ And https://files.dnr.state.mn.us/assistance/backyard/treecare/forest_health/whitesprucediagnosis.pdf Consider consulting with a certified arborist to help confirm the problem and to discuss treatment recommendations. I see from your city's website that you also have a city forester that may be able to come out and inspect your tree. Contact your city or see the website here for more information: https://www.ci.mahtomedi.mn.us/271/City-Forester You can also send a sample of your tree to the University of Minnesota Plant Disease Clinic. https://pdc.umn.edu. There is a fee for sample analysis.
