巨型红杉金博宝188电子游艺app网址是一棵外面的树。在生长季节，至少有一部分一天的阳光是为了生命力。当温度高时要小心。红杉会在炎热的一天的短时间内将所有水分从容器中吸出。如果夏天变得很热闹，将红杉移至更阴凉的地方，这样就不会变干。高温（100°F+）对叶子无害，但会导致根部枯萎。尝试在夏季（90°F或更少）保持根部凉爽。如果外部太热，可以将红杉送入房屋一段时间是可以的。只需记住，当温度更温和时，偶尔将它们返回阳光和空气。在寒冷气候下的冬季，危险不再是危险的，它再次脱水。 The trees can dehydrate even though the temperatures are below freezing. The best thing to do is to construct a well-drained cold frame and place the shallow potted trees into it. Water the trees well before the winter freeze. Where possible you can bury the trees in snow. They will remain in perfect condition, just as they do in nature, buried in snow for the entire winter. That will insulate them from the drying cold winds and preserve them perfectly. If there is no snow or cold frame possibility you may need to take them into a garage or cellar occasionally to protect them from drying winter wind. It’s not a good idea to keep them long in a heated house in the wintertime. The dormant trees are not able to pick up moisture rapidly enough to replace moisture loss to a heated room. A dormant giant sequoia bonsai will die if kept in a heated house for too long in winter.
