What is the best soil for stump bonsai _ How to turn over the pots and change the soil

Stump bonsai is also a kind of bonsai. What kind of soil is good for planting stump bonsai? Below I sorted out the soil selection of the stump bonsai, let's take a look.

What soil is the best for stump bonsai?

It is the best soil with proper acidity, drainage, air permeability, looseness and fertility. Soil can also be selected according to the needs of plants.

Soil preparation method:

We take the common pine and cypress stump bonsai soil as an example. The method for preparing soil is as follows: 1 part plant ash+1 part humus soil +3 parts garden soil +4 parts peat soil+1 part sand, all of which are evenly stirred and can be planted; Other soil preparation methods for stumps are: 1 part plant ash +3 parts humus soil +2 parts garden soil +3 parts peat soil +0.5 part sand, and plants can be planted after all materials are evenly mixed.

Soil treatment:

But before planting, the soil should be disinfected, sterilized and insecticidal before planting. If possible, you can try the following methods: pour all the mixed soil into a large pot for frying, keep the temperature in the pot at 80 degrees as far as possible, and stir at the same time, which is more effective than disinfection and sterilization with drugs.

If the stump is taken from Shan Ye, the original soil should be completely removed before transplanting it into the flowerpot, and then the soil should be selected and mixed according to the suitable soil of the stump.

Step-by-step method for turning pots and changing soil in stump bonsai

1, due to time.

Potted trees newly planted, newly planted in pots or newly changed in soil will not be fertilized temporarily due to root damage, and more fertilization will be applied when potted trees grow in the peak season in spring or early summer next year. Fertilization should be stopped when potted trees grow slowly in autumn and when potted trees have entered dormancy in winter. Fertilization should not be applied around noon in rainy days or at high temperature in midsummer, because fertilization in rainy days is easy to lose and damage the roots. Fertilization is best done on cloudy days or in the evening. When the soil in the basin is slightly dry, weeds in the basin should be removed first to loosen the soil, which is conducive to the infiltration of fertilizer and water into the soil, so as to accelerate the decomposition and absorption of fertilizer and avoid fertilizer damage.

2. Due to the quantity

Stump bonsai should master the principle of small amount and multiple fertilization, and the amount of fertilization should be small and thin each time. Generally, from beginning of spring to beginning of autumn, topdressing should be performed every 10 day/time (divided into 7 parts of water and 3 parts of fertilizer), and no fertilizer should be applied after beginning of winter.

3. Because of being fat

Nitrogen fertilizer promotes the vigorous growth of plants and has more pregnant buds. Commonly used nitrogen fertilizers are bean cake, ammonium sulfate and fertilizer water. Phosphate fertilizer promotes bright colors and plump fruits, such as calcium superphosphate crushed bone powder. Potassium fertilizer promotes the development of root system and the fruiting of plants, and is often used, such as potassium citrate and plant ash. Fertilization should be carried out according to the growth of plants, and at the same time, it should be mastered flexibly according to the characteristics and growth of tree species.

What stump is the best for bonsai?

Type selection:

If you want to see its piles, you can take leafy plants, preferably the kind with tortuous stems and small leaves, but many flowers and heavy fruits. For example, pyracantha fortunei, nandina domestica, Mahonia fortunei, Elaeagnus angustifolia, nanmu, oak, bird's element, etc. These are all evergreen varieties.

There are also deciduous varieties: wisteria, elm, anzhen xiaoye, triangle maple, crape myrtle, ebony, bayberry, boxwood and so on. Deciduous varieties are also divided into winter and spring, and stumps are suitable for bonsai.

The choice of vitality

How to see if the vitality of the stump is tenacious? Start with its bark and cut the bark of the stump with a knife. The inside is turquoise, with small water droplets oozing out. When you look at its branches, you can bend gently and resist bending, and you can obviously feel the strong moisture after they are broken; Finally, look at its roots, and there are also small water droplets oozing out after cutting, so this stump is very suitable for bonsai.

Appearance selection

First of all, we should have a strong appearance and a tall and straight posture. The whole plant rises steadily, the roots are thin, and the leaves are broad and shiny. The ascending arrangement of its branches should also have a certain order, and there is no need for additional truncation and trapping. With a little pruning, you can create a natural tree shape, which is suitable for use as a stump bonsai.

Matters needing attention

Special attention should be paid to watering in the process of stump bonsai maintenance. The way to water is not only to water the roots, but also to water the leaves. It is best to choose plants with smaller leaves as bonsai to avoid disproportionality.
