| Hi All, Really need some help quick! I have a 3-year-old sycamore tree which has done really well and is now 20+ feet
tall. We live in Deming, NM on the flat desert at about 5k ft. When the first buds appeared, maybe six weeks ago, we had a cold snap that zapped them (did the same for my fruitless mulberries). Nonetheless, I kept watering the sycamore and finally the leaves all popped out and it was a beautiful green sight in the front yard. ALAS - the past couple of days I've noticed the leaves getting grayish looking..........starting at the top of the tree, and have now started graying all the way down. Can't see any evidence of pests, but I sure hate to loose that tree. Green is sort or RARE around here, except for my evergreens. Any help will be greatly appreciated. |

| Take some pictures and post them, especially close ups of the underside of the leaves. There are a couple of pests that frequent sycamores, sounds like they may be picking on your stressed tree. hortster |

| Someone asked me to post some pics. Not sure how to do it, but will take a shot at it. Hope someone has some ideas so I can save the tree: www.garlic.com/~jimd/sycamore1.jpg www.garlic.com/~jimd/sycamore3.jpg www.garlic.com/~jimd/sycamore4.jpg www.garlic.com/~jimd/sycamore5.jpg www.garlic.com/~jimd/sycamore6.jpg I have thought about spraying the tree with soapy water, but figured I might wait until I hear something from someone on here. Many Thanks, Jim |

| Looks allot like a powdery mildew to me. Don't know how that would work in a high dessert though? Arktrees |

| we had a cold snap that zapped them ====>>>> first.. how about some pix i can actually focus on???? now.. i can NOT tell if its cold damage.. but if it is.. then spraying them with anything is .. frankly .. pollution ... if other trees.. your mulberries.. were also damaged.. i dont understand how you can call that cold damage.. but think this damage is something that requires a chemical fix ... dont get me wrong.. i am all for chems.. when the problem can be properly ID'd ... and used according to label instruction ... can you get us a decent picture.... of a leaf or two.. plus a good overview of the tree in toto ... to see any pattern of the damage .... and.. how cold did it get .... and at what leaf stage was the tree at when it happened??? dont forget.. sycamores do have fuzzy backsides .... ken |

| Arktrees: It it is mildew it is "rust mildew" rather than the "powdery" one, cuz there are no white spots on the leaves. Ken: As I was just out looking for the white spots, I noticed that within the past four days, something has also damaged my pecan worms/blossoms. It didn't get them "all" and the it didn't get "all" the leaves and little pods on the sycamore. We check the weather all the time and still don't think that it got anywhere near freezing here in the past few weeks, but it looks that way. It also looks that something has "stunted" my mulberry greenery after they were recovering from the really cold snap a few weeks back. So, it is possible that it was the cold, but can't say for sure. I have some tomato plants by the house and out in the garden (sheltered only by lattice panels) that didn't get damaged. Go figure............you guys I'll try to get a better picture. My wife does all the photography around here, and didn't quite understand what was needed. Will get and post them shortly. Many thanks, Jim |

| Hi Everyone, Here are some more pics showing the full tree, the good, the bad and the ugly. Hope you can determine something from them. Thanks a bunch. Jim www.garlic.com/~jimd/syc-tree1.jpg |

| WAG .... i have no real clue... check the link.. do any of the images look familiar?? ... flip to the web side ... ken ps: so you guys dont do lawns.. eh??? .. more of a rock thing.. fascinating.... |
Here is a link that might be useful: link

| Lawns! What's that I also just noticed that the second cold snap also got my the re-growth of my mulberry trees. We certainly didn't think it was that cold and it WAS NOT down to freezen, but maybe in a "weakened state" it didn't have to freeze. The winter has been the worst (coldest) in anyone's memory. We have only been her 6 1/2 years. May have to stick with evergreens. Planted 10 Thuja Green Giants just in the past few days. Am anxious to see how they do. Planted 20 Afghan Pines about 5-6 years ago and have 20 healthy Afghan Pines today!! Just planted two peach trees. Didn't do well with the last two fruit trees I planted. Thanks Ken, I appreciate you help. Jim |

| Ken: Based on the pictures in the link you listed, my tree is badly infected with anthracnose which can be treated with a fungucide. Also, if the limb itself dies, cut it off and burn it. Alas!! Anyway, I'm glad I found the problem. The conditions were right for it, too. BTW, Are we only allowed to reply ONCE on the same topic? Regards, Jim |

| hey garlic you can not post two answers in a row .. w/o changing the title ... but i would await confirmation here .. i made a SUGGESTION ... i claim no expertise in diagnosis .... back in the 60's or 70's .. in my neighborhood.. the city had to repeatedly spray the 30 foot sycamores for such ... God knows what they did to us kids ... in my world ... if the ID is confirmed.. i would be done with the tree .... as i would not want to deal with spraying at height .... nor willing to invest to have it done professionally ... it only gets harder and more dangerous as the tree gets taller ... your best bet.. to confirm the ID is to contact your COUNTY extension or Ag office.. and ask them to come out.. or make an apptment to meet with the tree guy for a local hands on diagnosis ... i would not rely for diagnosis on the guy who wants to charge you money for a remedy ... once you have such .. then you can contemplate aerial application of chemicals ... eh??? good luck ken ps: i guess you dont have to mow the lawn .... but then you dont have the cooling effects of a green grass ... what do you have to do to maintain rock .... backpack blower???? |

| Definitely sycamore anthracnose, which is really the only major disease problem this tree has. It is not uncommon to see sycamores in SoCal (where they are widely planted as street trees) virtually leafless due to anthracnose. Consistent defoliation will weaken the tree, eventually significantly shortening its lifespan. Treat now to make sure the disease does not take hold - early signs now on young trees generally indicate the issue is not yet systemic and more of a blight situation. If stem cankers start to appear, best to remove and replace. |

| IMHO ... a blight best cured with a chain saw ... seriously .. you cant find a better tree??? for what you spend in chemicals and a sprayer.. you can buy a new tree ... and not expose yourself to chemicals ... or better yet.. plant a replacement.. then mess around with trying to save this one.. and when and if you fail ... the other will be on its way ... like you wouldnt benefit from the shade of two trees ... ken |

| with the crumb munchers around.. i would not mess with aerial spraying.. but if you want to go at it.. good luck to you .... the email address is my last name.. and my wifes last name ... 40 years later.. the sycamores are still in dad's old 'hood ... so cure is possible... i just question your exposure at application at height ... ken |

| In agreement with the don't bother treating folks. Sycamores get Anthracnose every year and shrug it of, they have adapted to live with it. Only in rare situations when the tree is otherwise unhealthy will it really bother it. |

| Had the same problem two years ago with 11 Sycamore trees on my property after a rather wet spring. I'm not an arborist, but I notice a lot of the oaks around here (Central Coast California)have a fungus that they call "Oak Tree Decline" or something like that. Had a guy come out and spray once at bud break, didn't have him do the second spray as recommended after the leaves came out and the trees are doing, eh, okay. Seem to be rather hardy trees in my humble opinion. Stil, they are twiggy and I still get some dead small limbs breaking off every once in awhile. |
