1、 Do you need to soak in water

Elm down the mountain pile can't soak in water. Because elms like to be dry and afraid of being wet, and when they are dug down the mountain pile, the root mainly focuses on repairing the wound and can't absorb water, so they don't need to soak in water. Soaking in water will make the wound of the stump infected with bacteria, which is not suitable for healing. You can apply wound healing agent or beeswax paint to the wound to prevent bacterial infection. In order to prevent the water loss of the plant, it can be moisturized by spraying water on the suit, branches and stumps. When planting, use wet sand for deep planting, and pour root setting water after three or five days. It should be noted that when planting in the first year, shade should be provided throughout the year. Do not maintain the old pile in the direct sunlight environment, and it is best to place it in the shade

2、 How to judge

1. It grows well. If the leaf color is shiny, the speed from light to deep is fast, the leaf quality is thick, the nodes are dense, and the branches are thick. After two or three months of growth, the color from light to deep and the lignification is fast, it indicates that the elm may have survived

2. If secondary buds can germinate in spring or early autumn after planting, the survival rate is high

3. In summer, no new leaves turn yellow, and the branches will not shrink back. It is easy to spend summer and can resist the destruction of winter, indicating that the stump may have survived

4. The soil in the basin dries rapidly, indicating that the stumps have survived
