现在苹果树叶子都黄了,掉了一大半了. + j% A) F+ o9 d& m4 _今天下午,我给所有的树都浇了很多水. 但愿他们能好好过冬.& m) y5 b3 N, c/ i
我打算找点儿旧衣服或者毛毯什么的,明天把苹果树的树干包上,你看怎么样?
you don't need to do it right now. It is still early. The part just above ground of the trunk is quite sensitive to cold weather but if it is covered by snow, the tree should be ok. Therefore, my suggestion is do this way only under this situation: the low temperature goes down to -20 steadily without snow covering the lower part of the trunk. Thanks and Good luck!
