Methods for artificially cultivating bonsai tree stumps (how to cultivate newly dug bonsai tree stumps)

How to cultivate the stump embryo of "tree stump bonsai"

First, pile planting:

A lot of preparation work needs to be done before planting tree stumps, including repairing wounds, selecting branches, and choosing planting materials:

1. The wound of the damaged root is uneven, which will increase the time for wound repair. Some roots that have already peeled off the cortex may even rot. Before planting, trim the cut end of the root to be smooth and without burrs.

2. Root pruning will temporarily lose the ability to absorb water and nutrients, and it will take some time to recover. At this time, the water consumed by the branches and leaves can only be extracted from the tree body. Why do we need to prune branches and comb leaves to avoid excessive water consumption?

3. The tree stump bonsai should be "small to see the big", so it needs to be dwarfed. When dwarfing, select the side branches on the main trunk that can be oversized to the main trunk for trunk pruning. After pruning, adjust the angle of the side branches to become the main branches.

4. When cultivating piles, all the planting soil should be river sand. The nutrients in the nutrient soil coexist with bacteria. The large wounds at the roots cannot filter out bacteria and are easily attacked by bacteria.

Therefore, river sand is clean and sterile, can retain water without accumulating water, and is the best soil for growing trees. Some trees need to be wrapped with plastic wrap or bagged.

Second, pile management:

1. Management when just planting:

Newly planted tree stumps need to be kept away from strong light and high temperatures. At the same time, the environment should be humidified. Moist air can reduce the increase of water and replenish water through the absorption of the branch cortex and leaves. According to the dryness and wetness of the sand, "don't water if it's not dry, and water thoroughly if you water."

When the shallow surface soil of the tree stump is dry to a depth of about 3 to 5 cm, add water in time. When watering, let the water flow through the planting container. Spray around the tree stump every day and wet the trunk and branches and leaves. Generally, it takes 3 to 5 times.

2. Germination management:

Most trees sprout first and then take root. After the new buds grow, don't pick the buds and branches too early.

New buds assist old branches and leaves in photosynthesis, which can promote the growth of roots inside the soil. It is recommended to start the budding stage about 2 months after planting.

The old roots of the stump can generally recover their ability to absorb water in about 20 days after replanting, and new roots will also begin to grow in about 20 to 30 days. After two months, when the new root system matures, bud removal and pruning can be carried out.

We can select and discard some branches based on the general outline of the bonsai, keeping the strong ones and removing the weak ones.

Third, management after survival:

Generally, after about half a year of planting, if there is no obvious weakening of the tree and the second wave of buds appear, it is basically alive. After it survives, you can shape the branches slightly .

Generally, the bonsai branches of tree stumps are mostly horizontal or fall downward. After the branches grow for a period of time, they can be adjusted according to the angle of the shaped branches. Generally, aluminum wire is used for winding, and then horizontally bent or pulled.

If there is a need to store branches, after the angle of the branches is adjusted, there is a transition to the branches of the next level, which is called a perfect ratio. Then cut short. It is generally recommended to keep 3 to 4 buds for large branches. It is recommended to keep 2 buds for small branches with strong germination.

Fourth, water and fertilizer management

In the stage of tree stump cultivation, fertilizer is basically not used. After the tree stump is alive, if the buds are not in place, the buds are not full, and the buds are weak.

You can use "gibberellic acid" diluted with water about 800 to 1200 times, spray the trunk, or irrigate the roots. When there is no germination but buds need to grow, you can use a brush to wipe the cortex.

The first fertilization can be carried out when the first wave of bud growth reaches 30 days, or when it has grown to about 8 to 12 centimeters.

The first fertilization should be diluted a certain multiple of the daily fertilization for bonsai maintenance. It is recommended to use organic fertilizer water to promote growth. Dilute the fermented "bean cake fertilizer" water with water at a ratio of 1:5 and pour it on the flower soil. Organic fertilizer water has a faster fertilizer effect.

After about half a month, you can switch to solid "organic fertilizer sheep dung balls". Solid base fertilizer is mild and has a longer-lasting effect. For later fertilization, you can follow the same fertilization method for daily bonsai maintenance.
