枫下沙龙 / 花鸟虫鱼 / 求教，请看图，树杆上的青苔对树有害吗？我已经死了一颗大树，不能让它走啊！预谢。 -sandy77(Thanks4Help); 2019-5-22 {58} (#12104364@0)

既然这么对你重要，有专门治理树的专家，花钱请一个到家里看看。 -tianyaca(tianyaca); 2019-5-22 (#12104392@0)
原来大树也那么脆弱的啊 -misssummer(Misssummer); 2019-5-23 (#12104508@0)
我猜没事，否则的话潮湿地区的树都长不大了。 -anexplorer(页于); 2019-5-23 (#12104585@0)
CBC99.1每天中午12点，好象有个园艺专家节目，专门接听电话，回答各种园艺、植物、花草问题。 -cc-pc(我到人间只此回); 2019-5-23 (#12104586@0)
不见阳光就会长青苔，没听说有危害。前几年很多落叶树死了是因为冬天冰雨后急剧大风降温把树给冻死了 -gavin_1000(风过无痕); 2019-5-23 (#12104597@0)
