| I have this tree which is in a line of trees in my yard. Recently it started turning brown and now is moving to the next tree. It shows no sign of bag worms which I have had problems with previously. Thanks in advance. |

| IL hot summer toasted your arborvitae. You can drive all around IL and see the exact same thing from city to city. Dax |

| I would tend to agree with the statements about the heat, but it is in a line of 25 with the most shaded and whatever it is, is transferring to the next tree where it is touching which leads me to believe either some kind of insect or disease but I don't know. I will post a pic of my treeline and the back of it which is alot more green right now. |

| but it is in a line of 25 with the most shaded ==>> if you mean the affected ones are the most shaded.. that means those are the ones closest to the large trees.. which means those large trees stole what little water there may had been.. from the trees in the shade ... what are the tree??? .. pix of leaves will get you ID's .. and i bet they are none of the trees that play nice with competition ... there are very few.. IF ANY .. bugs or pests that attack thuja ... in a manner which would lead to death ... if you find such .... they might write scientific papers on your trees ... IMHO.. somehow or another.. its a water issue ... ken |

| This shows how it is starting to mess with the next tree. All the leaves are gone from the other tree but I will see if I can find one on the ground. Other pics on the next posts. |

| This is the bare spot you see in the second picture I posted on the right side of the tree. It had a large spider web in it at one time but is gone now. |
RE: Tree turning brown

| Shags, since it is whole, discreet sections of those arbs that are dying, and since they appear to have multiple main leaders, is there by chance some girdling, ie gnawing of the bark by rodents down near the base? I didn't see any but that damage reminds me of what might happen from such chewing. If all the bark is gone all the way around a stem, very likely no sap flow is occurring above that point. Again, I don't see this girdling, but the damage reminds me of plants where it has occurred. +oM |

| Here is the whole tree line that T's into the lot dividing tree line. |

| I will check for gnawing as we do have some moles and shrews around and report back. Someone told me to check for spider mites but I am not sure how to do that. Which is whay I posted here. |

| Here is a better close up of the tree bare area. I am going to post another of the leaves of the nearby tree and some insects I found on the tree that got on me when I ran my hands through the foliage. |

| Bugs Well not so good of pic. |
RE: Tree turning brown

| I didn't see any gnawing on the tree though the "trunk s" looked wet. |
RE: Tree turning brown
| | |
| Trunk area looks black. Wonder what happened there. Something sure did. +oM |
RE: Tree turning brown
| | |
| You know what is wierd is that I have dead foliage on the same trunk/branches. Patchy whatever it is. |
RE: Tree turning brown
| | |
| Ok now looking at my last post I meant that there is alive and dead on the same branch. lol |

| I don't know about your tree, but spider mites leave very fine webbing, almost like a diaphanous fabric, and can be well controlled by wetting the foliage down daily or even twice a day for a week or two. Spider mites like dry conditions and hate wet foliage. They are arachnids and not insects, so insecticide won't help--insecticides will eliminate "good" bugs that prey on spider mites, actually. Again, though don't know what's going on with your tree. Is it possible that particular area is much drier than the rest of the row? The others look good. |
RE: Tree turning brown

| I don't think that it would be drier but never know it is more shaded on that end. Now it is very brown on one side but green on the other. Except for a patch of green on the brown side. I will water it down but it is supposed to rain for the next couple of days so I will see. |
RE: Tree turning brown
| | |
| The black on the base is now gone. It must have just been wet but it is definitely moving to the next tree and I am really worried about these trees. |
RE: Tree turning brown
| | |
| Is there a disease that may cause this browning because it is surely jumping between trees now? Thanks |
RE: Tree turning brown
| | |
| Could be Phytophthora root rot - that'll spread from one tree to the next underground out of sight. Resin |

| Is there anyway of knowing and if so how do you control it? Thanks |
