How to deal with the rotten elm and the wound?

Before making bonsai, it is necessary to do a good job of raising piles, planting the newly dug elm stump in plain sandy soil after treatment, or planting it in a tile basin with wet sandy soil for maintenance, so that the stump can take root and restore growth. At the same time, the dead branches, diseased branches and roots were pruned. After the plant restores growth, the plant is potted and maintained normally. After that, we can prune and shape the plants, according to the basic shape of the plants, we can choose to make bonsai in the form of straight stem, cliff, jungle, stone and so on.

1. Reason

The main reason why elm trees rot and flow liquid is the wound caused by pruning, and then the sap will flow out of the wound. If the elm trees are not treated in time, the sap will not stop flowing.When pruning elm trees, the uneven cut plants recover slowly, causing the wound to drain liquid.If the wound is not treated in time, the wound will be infected with bacteria and difficult to heal, and in serious cases, the plant will die.In addition, the rot and sap flow of elm trees without pruning may be caused by pests.

2. How to deal with

1. If the wound is small and the flow is not much, you can simply trim and disinfect, and then directly dry the wound.If there is a dry roll around the wound, it means that the wound is about to heal.

2. If the wound is large and the liquid is not stopped, the medicine can be used to make the plant recover quickly.First, use plant ash to absorb the liquid from the wound, and then spread a layer of plant ash on the wound.Alternatively, a wound heal agent may be applied to that wound.After a simple disinfection of the wound, some wound healing agent can be applied.In addition, you can also apply red plum ointment on the wound, which will also be conducive to the healing of the plant.

3. If it is caused by insect pests, it is necessary to use drugs according to the disease and the cause of disease.Use a potion from the wormhole to kill the pest.At the same time, it is necessary to prevent the occurrence of other diseases and insect pests and reduce the occurrence rate of elm sap flow disease.
