Is My Apple Tree Sick? (or how to take better care of it)
Ted,
Apparently we are not just in any old zone 8's in Oregon, but both in Portland. But you sound like you could be a native, whereas I am a transplant. I think I've been here long enough now though that my root system has recovered. ;-) "Ted Mittelstaedt" wrote: Thanks! I hadn't considered that the root system might be the issue. I watched the tree being dug up and there were several 5m roots that were cut to get it up out of the ground. The guy I got it from assured me that trees in Oregon grow like weeds and it wouldn't hurt it. They do grow like weeds, but even a weed will be set back by having that much of its root system removed. The older the tree, the higher a percentage of its roots are lost during transplant. It might take a few years to recover 100%, as it will probably take several years to grow roots out five meters again. None of my fruit trees have produced more than a few token fruits in their first year after transplant, even though they all did flower that first year. Since you got some apples in the first year, hopefully you are getting good pollination from somewhere, and next year you will get more fruit. Not all varieties can pollinate each other though, and sometimes pollination is only unidirectional (variety A can pollinate B, but B cannot pollinate A). When I was about 14 years old (quite a long time ago) a neighbor who was really into roses helped me to grow and prune the 8 roses in my parents front yard. That yard was basically barkdust and roses. I ended up entering some of them in the Portland Rose Show that year and the following year and ended up winning some ribbons. Congratulations! I remember Black Spot as well as some of the other rose diseases. Roses are the type of plant that you either spend a lot of time working on them or you just ignore them and hope that occassionally you get a nice flower. But they don't look good unless you give them constant attention. And they also don't look good unless your constantly at them with the fungucide and the pesticides. Occasionally I find someone who has rose plants that are healthy without chemical intervention, but this seems pretty rare. I've always thought they have beautiful flowers but the plants themselves are just butt ugly. (They are also closely related to blackberries, which are even butt uglier plants.) The prior owner of our house was a nut for roses, so there were about a dozen and a half of them in the yard. He used to chemicalize them to fight the fungus, but we do not. Generally they look great in the spring, then lose pretty close to 100% of their leaves to black spot during the course of the summer, then get more leaves in the fall. During all this time amazingly they still produce blooms -- sometimes quite a lot of them -- but there is is really nothing worse looking, IMO, than a past-its-peak rose blossom on the end of a dead-looking stalk with nothing else on it but thorns. This year one of the three remaining rose bushes we have not removed is actually holding most of its leaves with very little disease, even now in deepest August. Perhaps its immune system has finally caught up with the program. Or perhaps it's just luck. Or the cool summer. Take your pick. My impression is that roses have been bred so heavily for huge spectacular blooms that pretty much everything else -- like a halfway decent immune system -- has been stripped out of them through in-breeding. Well in my case I'm really limited in what I can do with the yards. The first problem is both are small - the back is about 12 feet wide by 20 feet long, and is on the north side of the house. I learned from a book on the "home orchard" that one can put up to four semi-dwarf fruit trees in a single hole, in a square only 18" on a side. I didn't try four, but I did put two plums in one hole and two apples in another hole, where each pair was selected to be mutually cross-pollinating. To be on the safe side, I also picked all varieties that are self-fruitful, however supposedly such trees will produce more and better fruit if they are cross-pollinated. This is a great way to pack in the multiple trees needed for cross-pollination when you don't have a lot of space (and my yard is similar in size to yours, although I am more blessed with sun). Another way is to get those trees with branches of multiple different varieties all grafted onto the same trunk, but then you are at risk of losing a variety if a branch dies, and also as the tree grows further any new branches are going to be whatever variety the trunk is, which may not be a desired one. So this approach seems more limited to me, and the trees cost more as well. Utopia in Decay http://home.comcast.net/~kevin.cherkauer/site Kevin Cherkauer |

Is My Apple Tree Sick? (or how to take better care of it)
Also remember that the original or maybe old growth apple trees did not
produce heavy crops every year. The tree seemed to know (teleology(?) speaking) that energy would be better spent in root food for storage as starch. The apple trees now demand heavy crops every year. Maybe yours is one of the good old ones! I have often wondered what old growth forest or fields with apple trees would be like. I guess they would be in Russia. I wonder what their true companion plants are? -- Sincerely, John A. Keslick, Jr. Consulting Tree Biologist http://home.ccil.org/~treeman and www.treedictionary.com Beware of so-called tree experts who do not understand tree biology. Storms, fires, floods, earthquakes, and volcanic eruptions keep reminding us that we are not the boss. Some people will buy products they do not understand and not buy books that will give them understanding. "Ted Mittelstaedt" wrote in message ... Hi All, I am in USDA zone 8 (Oregon) and I have a question about an apple tree in my yard, the cultivar is Transparent Yellow (or Yellow Transparent) on a semi-dwarf rootstock. I got this tree from a guy in the area who grafts apple trees as a hobby and was thinning out his garden in Oct 2007. The tree is about 6 years old I think he said. (I had actually been looking for this specific cultivar for several years) Anyway, I planted it according to the generally accepted planting directions, dug a big hole, watered it, mulched it, made sure the tree wasn't planted too deep and all of that. This was around Oct 2007. The tree needs a bit of pruning, I decided to hold off on it for a year to make sure it would survive transplant shock. The one bit of pruning I did do around May of this year was the tree had 3 verticals competing to be the leader, I topped 2 of them and the remaining one I nipped 2 of the top shoots to leave a single one as the leader. This single shoot grew about a foot this summer. So far so good. Now, here is the part I'm concerned about. This spring (April) the tree flowered, here are the pics of it: http://www.freebsd-corp-net-guide.co.../apr-tree1.jpg http://www.freebsd-corp-net-guide.co.../apr-tree2.jpg http://www.freebsd-corp-net-guide.co.../apr-tree3.jpg Then in May, most of the flowers dropped off leaving the green fruit spurs (I also own an Indian Summer crabapple tree planted in the front of the house that flowered at the same time as this one did, I assume they pollenated. The Indian Summer produced -lots- of crabapples.) Then in late May just about all of the fruit spurs withered, wilted, drooped over, got brown and dropped off. The leaves were not affected, just the fruit spurs. The tree produced a total of 6 apples. The apples that WERE produced were perfect. (tasted exactly like transparent yellow, at least like how I remember transparent yellow tasting from 25 years ago) Here are the pics from that: http://www.freebsd-corp-net-guide.co.../jun-tree1.jpg http://www.freebsd-corp-net-guide.co.../jun-tree2.jpg http://www.freebsd-corp-net-guide.co.../jun-tree3.jpg http://www.freebsd-corp-net-guide.co.../jun-tree4.jpg The apples started dropping in early August, which is normal for this cultivar. However, now the tree seems to be beginning to show fall colors, here's current pics: http://www.freebsd-corp-net-guide.co.../aug-tree1.jpg http://www.freebsd-corp-net-guide.co.../aug-tree2.jpg http://www.freebsd-corp-net-guide.co.../aug-tree3.jpg http://www.freebsd-corp-net-guide.co.../aug-tree4.jpg http://www.freebsd-corp-net-guide.co.../aug-tree5.jpg http://www.freebsd-corp-net-guide.co.../aug-tree6.jpg Now, I'm not particularly upset about the yield this year - if the tree had produced a big crop of apples I would have pinched most of them off very early since I wanted the tree to put it's energy into establishing it's root system, not producing apples. But what concerns me is that it -appeared- that most of the blossoms pollenated and were well on their way to producing apples - then just abruptly died off. I have looked up the diseases of apple trees to see if there is a match to any symptoms. Blossom Wilt is one that might be a cause - but it is supposed to shrivel fruits and damage leaves, and that did not happen. There are no other symptoms. Unfortunately as Transparent Yellow is (apparently, nowadays) not commercially viable, nobody sells these apples anymore, and there is little information out there other than old charts of when it is supposed to ripen. None of the nursuries in the area (including one of the largest which claims itself as apple experts) have ever heard of this cultivar, and most of them in any case are more interested in selling you a "modern" cultivar with fruit that tastes like warm water, and has been (apparently) genetically engineered to be resistant to everything short of a nuclear explosion, I assume because once they have your money and their door hits your ass on the way out, they don't want to see you again - at least, not complaining about your tree you bought from them. I am hoping that someone with some of these who has some experience might be able to tell me if what I'm seeing is perfectly normal, or something to be alarmed about. Also I am wanting to know what I should be spraying, and when. Thanks! |

Also I am wanting to know what I should be spraying, and when. Thanks! From the pictures you provided, I was struck by the small amount of leaf foliage. This may not be a disease. Are you fertilizing and mulching this tree? The other concern I have is your climate zone. The Yellow Transparent is rated cold tolerant in your zone, but the other consideration is the number of chill hours this tree is receiving. Most apple trees need a minimum number of hours of temperatures between 32 and 45 degrees to satisfy their dormant rest period. There are certain low chill varieties, but I'm not sure about your variety. Is the person in your area who gave you the tree growing the same variety, and with what success? As long as the blossoms on your crabapple are opening about the same time as your apple blossoms, there should be no pollination problems. Your leaf damage looked minimal and the fruit did not look attacked. You may not have to do much heavy spraying. A general orchard spray applied as needed, should do the job. Sherwin |
