Why does Chinese fir peel during its growth?

Chinese fir peeling is mostly caused by poor ventilation and insufficient light. Of course, sometimes watering takes a long time (waterlogging is too frequent or watering is not good). It is recommended to put it in a well-lit place (a little shady in summer) and a place where there are no obvious objects around (try to put it in a place with space on three or four sides). When the topsoil is dry, water it again. Don't water it!
