Control of soil and temperature in Culture of Camellia Bonsai

In most cases, the new ones are the seedlings sold in the nursery, with nutrition bowls, or removed from the original soil and sold in the pot. Whether it is necessary to remove the original soil depends on the difference between the original soil and the new soil. If the composition of the newly replaced medium is not much different from that of the original soil, it can be put on the basin directly. For example, some people use red soil to add rotten leaf soil to sand, and if the original soil is very loose, it does not need to be removed. But if the original soil is thick laterite and the new medium is peat perlite, it is better to wash the roots.

You can soak it in a water basin or rinse the surface of the soil ball slightly to expose the white roots. I usually use peat mixed with red jade, whether the effect of washing the root is all right. Because the medium of growing tea is generally tight, the light medium of the drainage layer should be put in one more layer to prevent stagnant water. Check whether there are any diseases and insect pests in the new seedlings when you put them on the pot. Shell insects are common. Spray the medicine once and water it for the first time. After pouring it thoroughly, water it slowly again.

It is helpful to mix new and old media. Don't treat camellias in the same way as rose. Camellias grow slowly, if there is no special reason, it is best not to cut a large number of roots or leaves, otherwise the seedlings may hang. I think camellias basically do not need pruning when they slow down, unless they grow too long, and there is no need to get rid of all the buds, just remove some of them according to the age of the seedlings. Camellia originated in China. Like warm, moist and semi-overcast environment. Afraid of the high temperature, avoid the scorching sun. The optimum growth temperature of Camellia is 18-25 ℃.

It is 13-18 ℃ from March to September and 10-13 ℃ from September to March of the following year. When the temperature is above 12 ℃, it starts to sprout, and when it is over 30 ℃, it stops growing. The initial temperature of flowers is 2 ℃, and the suitable temperature for flowers to open is 10-20 ℃. The cold-tolerant varieties of Camellia can tolerate-10 ℃ for a short time, and the general variety-3-Murray 4 ℃. Leaf burns occur when the summer temperature exceeds 35 ℃. Camellia is suitable for sufficient water, humid air environment, avoid drying. Hot and dry summer and autumn

It should be watered or sprayed in time, and the air relative humidity should be 70% and 80%. Pay attention to drainage during the rainy season so as not to cause waterlogging and rot on the roots. Camellia likes fertile, soft, breathable, well-drained and slightly acidic soil. Generally, black soil, red soil, loose soil, sandy soil and mixing are used to prepare nutritious soil. Red soil contains a lot of organic matter, black soil has solidification effect, rotten soil has loosening effect, and soil can be improved by mixing.

The pH value of the soil is 6.5-7, which is the most suitable for the growth of camellia. In view of the fact that the single soil of camellia can not meet the requirements, it is necessary to choose several kinds of soil and medium to meet the requirements of camellia growth to the maximum extent. Mountain mud, perlite and rice chaff ash (6 ∶ 3 ∶ 1) are commonly used. This formula soil is especially suitable for family potted plants and has a good effect. After the nutritious soil has been prepared, sift it with a sieve, spray water slightly and bake it with fire.

Made into sterilized soil for spare, the sterilized soil has the advantages of no insects, no mildew roots, no smell and so on. Camellia flower seedlings must be planted in flowerpots in the shortest possible time in order to grow as they rise and not plant overnight seedlings. This requires that the flowerpot and pot soil (matrix) be prepared before buying camellia seedlings, otherwise the flower seedlings may lose water and affect the survival rate and rejuvenation after survival. The essentials of planting techniques: the roots of camellias should be extended.

Do not bend excessively to prevent the root system from being broken by pressing the soil above the root after covering the soil. The soil above the root should be pressed properly to make the root soil close together so as to improve the water absorption capacity of the root. After potted plants were placed indoors to prevent the wind from moving the camellia seedlings, resulting in a gap between the roots of camellia seedlings and the soil, affecting the absorption of water by the roots. The roots of the newly transplanted camellia seedlings were more or less damaged, and the water absorption capacity of the roots was poor.

Therefore, camellias must be pruned properly after planting to reduce water evaporation. Camellia must be watered thoroughly after planting. In order to prevent the water from being watered thoroughly, it should be watered again on the second and third day after planting. In the future, depending on the weather conditions, it will be watered every 1-3 days, and gradually transition to the watering frequency after normal management.
