I'm worried about My 50 yr old Oak tree
Washington Gas had to replace a faulty gas line and cut a huge trench three feet from my 50 + year old Oak tree. They cut a lot of roots. They filled in the trench. I'm not sure how much damage they did. There are a lot of cut of roots sticking up on top of the trench, so there has to be a lot more that they plowed under. The tree has got to be in shock. I'm afraid that they might have killed my tree. Is there anything I can do? Thank you,
Any digging, trenching, cutting within the root area of established trees will cause harm. Root damage may haunt the plant months or years later depending upon environmental stresses that occurred. There is little that can be done for damaged roots. Severe damage will cause branch dieback. All you can do is prevent additional stress. Keep the tree well watered during dry periods. Make sure mulch is no thicker than several inches and away from the base of the trunk.
The best thing to do would be to find a certified arborist near you using the following website from the International Society of Arboriculture. http://www.isa-arbor.com/findanarborist/arboristsearch.aspx?
