| I'm new to this site, so please bear with me! I have several questions about trees in my yard, but will post each separately. I have a Live Oak in my front yard and what the nursery called a City Oak in my backyard. Recently, both trees had random branches where the foilage turned brown and died. The Live Oak was not as severe and has rebounded and has new growth. The City Oak however has me a bit worried. As you can see in the photo, it has lost lots of foilage. The tree has been planted in our yard for approximately 6 years. I live in South Texas where it is very hot and windy. Although drought conditions have improved from last year, rainfall of late has been scant to non-existent. We have also had a winter freeze the past two years. I do not see evidence of a pest infestation. Additionally, there is major construction all around us, but not in close enough proximity to impact the root system of the tree(s). Any advice, suggestions, etc.? |

| It looks drought and heat-stress-related. Dax |

| welcome.. do not apologize any further.. we like to teach.. and even argue about it all between ourselves.. but w/o your ???'s .. we have nothing to talk about ... so have at it ... google does not ID a 'city oak' perhaps one of the sperts can ID it.. with a pic of the leaves ... and once you get an ID.. you can determine if its insane.. to have it planted under all those power lines.. or if.. IN FACT.. the tree is far enough away from them ... [it could be a camera problem.. but it sure looks like its only about 10 feet from that corner of the fence] .. you will be having great problems in a decade or two .. if its going to be an 80 foot oak ... and no.. i do not believe in ignoring such.. and leaving it for the next guy to deal with .. because you dont plan on being there ... there is one absolute in the garden.. the day after you say to yourself.. that is the perfect tree.. the utility will come thru and decimate it for you ... may as well do it yourself.. so you might want to think about all that.. or not.. i dont care ... ken ps: oh ... the branch.. with an ID.. we can then find out.. what if any problems there are with that tree ... in your area.. wherever that may be .... PpS: was it a rather large transplant.. and if so.. when??? |

| Drawing a complete blank on trees ID. OP, the guy that told you it was a "City Oak" either had a sly sense of humor or very low intellect! No such tree. Can we get a close-up showing leaves? +oM |

| I am going to speculate that the 'City Oak ' is a cultivar of Quercus virginiana called "High Rise ". It is purported to not have the horizontal branching infrastructure of the Live Oak species. It was becoming a much overplanted tree when I left that part of the country where Live Oaks thrive. I'll have to make a few calls to see if they have fullfilled the promise. Your tree looks planted too deeply. Number one reason for tree failure within the first few months to years. |

| Yeah, if an oak, it's definitely one with leaves lacking in sinuses of any consequence. That rules out anything I'd know! +oM |
|
| There's no reason why you should know this one, Tom! ;-) |
|
| FYI...regarding the 'High Rise ' oak cultivar. It does mature into a tree with a narrow, strongly pyramidal form, making it a good (if a little boring) city tree candidate. There are so many possible causes of the tree 's decline: lack of sufficient water, use of pre-emergent herbicides on the lawn, problems associated with the planting (yes, even after six years), and more. Decline from the top down like that is, in my experience with Live Oaks, caused by a problem associated with |
