Three problems that should be paid attention to in raising elm downhill piles

The excavation of elm piles should be carried out during the dormant period of plants. It's very cold in winter, and it's easier for old piles to survive before germination in March and April in spring. During this period, the temperature gradually increased, and the roots and buds of elm had strong germination ability, which was beneficial to the survival of old piles.

2. Pay attention to the sealing of root and trunk wounds.

After entering the spring, although the roots and leaf buds of plants can't grow, since the earth thawed, the sap of trees gradually began to flow, and the roots kept conveying juice to the branches to promote germination. At this time, the excavation needs pruning and pruning. If the seal is not good, the sap will be lost, and the nutrients and water of the stump will be consumed, making it difficult to survive. To reduce evaporation and nutrient consumption. It is necessary to apply wound healing agent or beeswax paint to the incision to prevent bleeding and bacterial infection.

3. Pile planting with thick soil.

After the old pile is cultivated, it can be cultivated in thin soil. Most of the classic elm bonsai we see are rarely planted with soil. However, when raising piles, thick soil is needed for cultivation. The purpose is to keep warm and moisturize. In case the old pile loses water. It is best to use sandy soil to avoid clay and nutrient soil with excessive fertility. Stump can be planted under sand, and two thirds of the stump can be covered with sand. When plants grow new buds and survive, soil farming will gradually decrease. It can also be covered with plastic film.
