It could be insects, like J said, or a culturally induced deficiency of Fe (iron) or other nutrients. Some things that come to mind: High root temperatures can be a major problem and cause the symptoms described. Over-watering can impair root function & lead to many different nutrient deficiencies and chlorotic plants. pH is a big possibility. Your MG fertilizer contains Fe and Mn, but if the pH is too high, these elements would be locked in insoluble compounds. Try adding an ounce of white vinegar to each gallon of irrigation water & see if that helps. If you have pH paper, add enough vinegar to reduce the pH to 6.0, and note how much it took. This will neutralize alkalinity and reverse the normal upward creep in pH. Your fertilizer (MG) contains neither Ca or Mg. Mg deficiencies usually show up in light green foliage. You might try adding the acidified water to a couple of plants and spritzing a couple of plants with 1/2 tsp MgSO4 (Epsom salts) in a gallon of water. If the plants you spritzed green up, yopu should include 1/4 tsp Epsom salts in each gallon of fertilizer solution when you fertilize. BTW - Ca deficiencies often show up as distorted new foliage. If you have a Mg deficiency, and you're using MG, a Ca deficiency is likely not far behind. The Mg deficiency usually shows up first because Mg is about 125x more soluble than Ca. Al

hey dude ... hard name to forget ... "didn't I try to talk you out of that tree a few years back ... lol ..." Yes probably so. Everyone said it was to big for that spot. And I said all the trees in my neighborhood are this big and bigger. "a quick check of the zone info indicates its a 3 to 7 .. and you seem to be zone 9 .... its no wonder you are having problems ..." This is California everything grows here!:) There are thousands of maple tree trees all around and they look great. As mine did just a few weeks ago. I either got behind on the watering or over fertilized around the tree. "how big was the tree when planted [rootball size]... how deep do you figure the roots are ... how much water do you think is actually getting down to the tree roots, before the ambient air and the grass.. suck it all away .... dig a small hole.. and actually see what if any water is 6 inched down ...." 15 Ft. Tall. It came in a very large plastic container. Iv' e been soaking it good yesterday and today. I'm going to clear the grass away around the tree and mulch it. I should have done that a long time ago. "IMHO .. no science here .. all leaves that turn color in late fall .. and even those that dont ... are dead.. and diseased ... that is kinda the whole point of falling off ... its just part of nature .... i would NOT consider any treatment .. organic or not ..." I have seen these Autumn Blaze trees around here and they are a beautiful Red at the end of the year when everything is done right. "is there any impact from the blacktop on the tree ... like the road being on the south or west side.. and cooking it from below... while the sun cooks it from above... maybe that is why only highly hidden leaves perform properly ..." No this is happening all the way around from top to bottom. Just the leaves right on the trunk are perfect. "how long has it been there... is it fully 'established' ... it might be a maturity issue ... i think of trees in terms of hundreds of years.. not along the lines of.. i planted it 2 or 3 years ago ... and it is failing me .... perhaps color will come.. with patience and proper water ....." about 5 years ago I planted it. and mulch and a water meter I should be ok. "every post you have ever done.. is of that little patch of grass ... how about a pic of the rose garden ???" See below. And you can find many of my post over at the Rose Gallery and the GW Fruit and Orchard Forums. "good luck" Thanks to you all for your help! I believe you guys are right. This is not fungus. The ground has felt hard there for a while. I should have known. I think it is a combination of not enough deep watering. The root zone got too dry and than the miracle grow Burt it. I will have to wait till next year for the tree to all turn the Autumn Blaze color. At least you guys help me figure out why this keeps happening around this time every Summer! You would not believe how healthy and Dark Green it looked just a few weeks ago. But we have had a long hot dry Summer here. And we got very little rain in the Spring. And here I thought the tree pretty much found water down there somewhere. I did not realize it would totally dry out down there. Thanks Again All! Dave Here are the roses pics requested. Here is a link to a couple of Thousand more pics if your interested. http://www.fototime.com/inv/F0A2F4D624CDA2A Here is a link that might be useful: My Fototime Album

I'll have to take another pic of the last one. It has round red and black berries. I was outside with Mercedes when I took those because she was restless and kept wanting to go outside so I took the camera and we went out for a while. I wish I had known what was going to happen I would have taken a last pic of her but its better to remember her when she was well. Yes she was old and her heart gave out. She has been on heart meds for a a few months and the vet didn't tell me that it would only work for a little while. He wasn't surprised when I called him at 2:30 this morning and said to just let her go there was nothing more to be done for her. Enough about the sad part. The red plumie smells just like deep red roses. The really big brug in the bed out back is Naughty Nick. He lost all his buds when it got hot again. No Karyn, the new leaves look funky on the Daydreams but the others that got burned look ok now that they lost the affected leaves. Do you think I should destroy the Daydreams? I am now worried it might be a virus.

I am sick! I'm losing several beautiful Bracken's Brown Beauties. NOT yellow leaves, we're talking dark brown and drooping leave. Trees are near easement. Either the county (which is always so very helpful!!!!:( :( :( when it comes to killing plants, sprayed a strong herbiside on the easement to knock down tall weeds, or Scott's lawn service killed them with herbiside. Magnolias along border of easement. I'm betting it was county!!! Past experience. I planted Carolina jasmine to help control erosion and create beauty on the culvert, put out 75 plants. Lot of work, no small expense. Some fool from the county hit it with kill-all herbicide. Yes, high grass should have been mowed. But I can't do it because the sides of the ditch / easement are so steep and difficult to mow. I've almost turned the lawn mower over on myself several times trying to mow it. My husband doesn't have any problem mowing it, but absolutely won't get around to doing it! Hence the county herbicide spraying. And now killing I don't know how many of my beautiful magnolias. I'm real angry. Having a terrible day. Really. I loved /babies all those trees! Nothing but a crime to kill them!
