Bark has been sloughing off and branches dying. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13969 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13969 Thu, 17 Sep 2009 09:15:28 CST Client purchased Mountain Ash tree 3 years ago and it produced the typical red berries the 1st year. Last year no flowers or berries. This year the white flowers were produced in the spring but now there are not clusters of red berries. Is there a reason why it may not have produced berries and if there ever will be berries again? http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13922 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13922 Thu, 03 Sep 2009 08:45:40 CST Five hickory trees (one mature and four young trees) have been showing signs of decline for several years. Galls are present and leaves have been dropping all summer. Any ideas on the cause or what needs to be done to save the trees? http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13883 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13883 Thu, 20 Aug 2009 04:09:56 CST Ash tree going downhill. In 2008 tree had some leaves start turning yellow towards the end of the summer. This year the tree looked good to start and now the yeloow leaves are back and worse than in 2008. Possible type of ash borer or ash yellows? http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13867 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13867 Wed, 19 Aug 2009 02:35:33 CST I have received 2 calls about controlling suckers around the base of Canadian Red Cherry (Prunus virginiana, I beleive). Are there herbicide options that won't damage the parent tree? Thank you http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13855 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13855 Tue, 18 Aug 2009 10:45:37 CST 15 yr old maple tree (trunk 10" diameter) losing bark on trunk and limbs; seems to start in the crotches. 1/2 of tree did not leaf out this spring and started on the north side of the tree sometime last year and has steadily worsened. Looks like bark has been chewed away in sections. Suggested animal damage but client disagrees. Same thing is happening in another maple tree 10 feet away. Fir trees and ash tree unaffected. Water the lawn but not trees specifically and lawn care company treats lawn for weeds and applies fertilizer. Found what looks to be an immature western seed conifer bug on sample but found nothing else when peeled away bark. Note: the photos are taken from already dead branches.
