Root rot should pay attention to making the soil loose and breathable and not ponding. Common pests are sawflies, whiteflies, mites and Changbai scale, etc. Sawflies, whiteflies and mites can be sprayed with 40% dimethoate 1500-3000 times solution, Changbai scale except artificial brush, can also be sprayed with 40% omethoate 1000 times solution or 40% fenitrothion 500 times solution.
