1. ReasonsThe main reason why elm trees rot and ooze sap is because of the wounds caused during pruning, and then sap will ooze out of the wounds. If not treated in time, the wounds will continue to rot and ooze sap. When pruning elm trees, uneven cuts can slow the plant's recovery and cause fluid to ooze from the wound. If the wound is not treated in time, it will be infected with bacteria and difficult to heal. In severe cases, the plant will die. Additionally, sap rot that occurs when elm trees are not pruned may be caused by insect infestation. 2. How to deal with it1. If the wound is small and there is not much fluid discharge, you can simply trim and disinfect it, and then dry the wound directly. If dry curling appears around the wound, it means the wound is about to heal. 2. If the wound is large and the fluid does not stop, you can use medicine to make the plant recover quickly. First use wood ash to absorb the fluid from the wound, and then sprinkle another layer of wood ash on the wound. Alternatively, you can apply a wound healing agent to the wound. Simply disinfect the wound and then apply some wound healing agent. In addition, you can also apply red plum ointment on the wound, which will also help the plant heal. 3. If the elm tree rots and sap is caused by insect pests, it is necessary to use symptomatic medication based on the symptoms and the cause of the disease. Use chemicals to kill the insects at the holes they are in. At the same time, it is also necessary to prevent the occurrence of other diseases and pests to reduce the incidence of elm sap disease. |
