求教：我的白玉兰生病了，它好难受，怎么治好它呢？

去年春夏买了一盆白玉兰（缅桂），开始的时候，花叶都多多的，很开心。但是，秋天渐渐的来了以后，我的白玉兰就变成了一个病美人：还是在继续的开花，还是在继续的长叶子，可是，叶子长大一点就渐渐的从边缘开始烂掉，先是一个一个的小点，然后整片叶子变成铁锈红，最后慢慢的掉了。有的时候，花苞上也会出现这样的铁锈红点。

但是，虽然如此，新叶子和新的花还在渐渐的长出来，它并没有死掉。只是现在我的白玉兰变成了秃美人，未免不雅。




求教，到底是怎么回事？我自己仔细翻查过叶片，并没有看见虫子，也在网上查过，似乎不是害虫的原因。哪么是不是因为我以前浇水太多了？应该怎么治疗？

先谢谢大家。

多谢老姐！

我的预览现在又好了，夏天一到，叶子疯狂的长，又多由密，也不晓得为什么秋冬春三季半死不活的，有可能是水多+放在家里，缺少阳光……

谢谢你费心帮我寻找：）

10 Dec 2008, 11:12 AM I have a Michelia Alba for about four years potted inside the house. The leaves drops on & off but, I just notice my plant is dropping all it's leaves. I think I over watered it and now the root must be rotting. How do I salvage my plant? I realy love this plant. This is my favorite plant. Some great advice would be appreciative.

The only thing you can do now is not water your plant for a while until the container is very light. Also tip your pot slightly at an angle so that the water won't sit in the pot by putting small pieces of bark or pebbles on one end of the pot. Hopefully, new root will generate. Keep an eye on the green part of your plant to see if it starts to change color to brown. If it does, then your plants is in the process of dying and the brown color will start to run toward the main branch. Hopefully, it will stop before reaching the main branch. If you see new budds from the main branch that means you successfully salvage your plant. You might want to water your plant only once every two week during winter. You want to fill your pot with water all the way to the top and let it drains all the way when watering. In pot, do not over fertilize it because it is very difficult to salvage. Do not put your plant in place where there are a lot of draft. This plant does not like wind when it is not mature. Good Luck!!!!
