Sick Pine tree?
I have a very tall white pine tree that appears to be sick. The
needles on the tope of the tree are turning brown. This started before winter with only some small clumps throughout the tree but now large patches have formed. There is another large white pine tree right next to it and it is doing just fine. The two trees are the same size, which is taller then a telephone poll. There is another tree right next to it, the branches are touching, but the needles on this side are fine. Is this tree sick? The branches and bark appear to be fine but I'm not an expert. Any suggestions or information on tree care would be appreciated. |

If you can get to the top and cut it off it will be fine. Keep hacking it off until you find good wood and not a borer's tunnel. Get rid of the pest don't leave it around. I don't know all that much about them, I worked a few years on a landscaping crew and we had to deal with some of them. Kevin |

Sick Pine tree?
The conventional wisdom in my area is that if you get the pine beetle/borer
in your pine tree, it's only a matter of time until you have to take it down. By the time you see the brown needles, it usually too late for a remedy. Check around the bottom of the trunk of the tree; sometimes you can see the "sawdust" from the borers' work. If see this dust, your tree is in trouble. I suppose a certified arborist could provide you with an evaluation of the tree. Good luck. Joe Morris Please remove ZAP to email me.

I haven't seen any sawdust but I do notice a white/gray growth around
the stumps of cut branches. Some of the branches have also grown into power lines, could that have anything to do with it? "Joe Morris" wrote in message ...

Sick Pine tree?
Your pine has Marphistes Gall disease. This is caused by the Marphistes
mite which breeds in the summer and then the female deposits her eggs in the ends of the topmost branches. As the eggs hatch the larvae feed on the branch tips and also deposit their droppings in the capillary tubes in the branches. This chokes off the branches and causes the browning that you see. Get yourself a hose-end sprayer and a garden hose. Mix 8 ounces of muriatic acid (you can get it at any pool supply store) with a gallon of water. Pour part of this mixture into the sprayer and turn the water on. Try to get as fine a spray as possible. Concentrate the spray on the upper branches, but be sure to give the entire tree a thorough spraying. You should see results within a week. far7134 wrote: I have a very tall white pine tree that appears to be sick. The needles on the tope of the tree are turning brown.

Sick Pine tree?
I would like to say something here. You should not ever diagnose a plant
disease or insect over the internet without seeing a picture. Its preferable to see the whole plant or at least a physical sample. With that said, "brown needles" is an extremely non specific symptom and could be caused by a number of things. A top branch could have been broken partially in a windstorm and died. Could be a borer. Could be white pine weevil. Maybe the tree is near a road that is heavily salted in the wintertime. To the original poster: If your trees are of value, hire a professional to diagnose your problem. I would not reccomend blindly using a bunch of chemicals based on a guess made by someone who has no knowledge of the site and hasnt seen the tree. Toad |

Sick Pine tree?
Most of the pine trees i've known about, have gotten attacked by a borer
beetle. Once one tree in an area gets it, you might as well cut down all the other pine trees in the area too. Out here in california, almost all the highways were lined with montery pine trees, then about 10 years back we had a major problem with the beetle, and all the trees were either cut down due to disease, or pre-emptively.

I guess you just displayed your ignorance for the whole world to see.

Think about it. El Jeffe How exactly is that? By suggesting the poster be conservative and actually have thier problem properly diagnosed?? If accurate diagnosis of pests or abiotic problems and proper treatment is considered ignorance, I guess I must be ignorant then. Good job El Jeffe! Toad |

Read it REAL SLOWLY. Give it time to sink in. Think about it real hard. |
