How to cultivate珍珠黄杨 better
This article provides information on how to cultivate珍珠黄杨 better and the methods and skills for growing it. The following is a detailed introduction.
珍珠黄杨 is a typical high-altitude evergreen species with fine and solid wood, glossy leathery leaves, and slow growth, consuming little water. Cold resistance, drought resistance, and shade preference are its most notable characteristics.
Generally speaking, depending on the age of wild珍珠黄杨 and the degree of root damage, with proper watering and careful care within a few months to even two or three years after transplantation, there will not be significant changes in the appearance of branches and leaves. The younger the tree, the stronger the vitality of root cells, and the higher the chance of survival. However, even if it survives, it often shows slow recovery in spring, long dormancy periods, sparse and weak branches and leaves, and is often in a state of僵 but not dead. The older the tree, the faster the roots shrink, although the nutrients in the trunk can still maintain the leaves from immediate withering, it is ultimately difficult to change the fate of death. If new roots occur, attention should be paid to controlling water and providing appropriate lighting to help preserve and strengthen the roots, and it is crucial to avoid fertilizing too eagerly.
Long-term and extensive cultivation experiments under extreme conditions have shown that the care and management of potted珍珠黄杨 is not difficult if the following key points, similar to those of other trees, are mastered to maintain its normal growth state.
One: Potting - Avoid direct sunlight in summer
Potting珍珠黄杨 can be done in any season, with the dormant period or the plum rain season being the best. The soil for potting should be dominated by humus soil, paddy soil, or mountain soil, with slightly acidic, neutral, or slightly alkaline soil. If you are not satisfied with the local soil, you can mix the soil brought by the plant with one-third orchid soil or vermiculite, peat, etc. You can also add a small amount of soybean cake or soybean meal to the soil, which can ferment and volatilize into slow-release fertilizer, benefiting the plant slowly. The roots of plants grown in the ground are very developed, and some of the main roots can be cut and some fibrous roots removed when potting, avoiding compacting them in the pot. When potting, first place a screen or tile over the bottom hole of the pot, then place the plant and fill it with potting soil and water thoroughly.
After repotting in summer, it should initially be placed in a shady and well-ventilated area. More sunlight should be provided in spring and autumn.
Two: Watering - Water when dry, and water thoroughly when watering
How to cultivate珍珠黄杨 better
Watering is the main measure for the care of potted珍珠黄杨. After potting, the plant should be watered sufficiently or soaked, and then follow the principle of watering when dry and watering thoroughly when watering. Dryness refers to the soil surface starting to look dry and white, not completely dry.
When trees are planted in pots, the soil is limited, and the water content is also limited. Without long-term water supplementation, the trees will lose leaves and even wither due to lack of water. Generally speaking, when珍珠黄杨 is placed indoors, watering does not need to be too frequent. If watering is too frequent, the potting soil will be too wet for a long time, lack ventilation and sufficient sunlight, and easily cause root rot due to hypoxia. The frequency of watering should be determined by the season, weather, and soil permeability. Watering can be done by spraying the leaves or watering the roots or soaking the pot for a few minutes, making sure not to create a situation where the surface is wet and the inside is dry. If you often go out and can't water, you can use 2-3 cotton or wool threads, with one end inserted into the pot and the other end soaked in a pot, cup, or other container, using the principle of self-suction for water supply. In winter, when water evaporation is slower, 1-2 roots can be immersed in water, and in summer, it can be increased appropriately, depending on the climatic conditions of your area.
Three: Fertilizing - Apply thin and refined fertilizer
The soil in the pot of a bonsai is limited, and the nutrients are also limited, so attention should be paid to the supplementation of fertilizer. However, as珍珠黄杨 grows relatively slowly, fertilizing does not need to be too much or too frequent, twice a year in early spring and autumn is suitable. Fertilizing potted珍珠黄杨 should focus on nitrogen. For a plant with a diameter of about 20cm, you can use about 20 soybeans or soak and fully mature soybean cake and dilute it with water before applying it to the potting soil.
When using other liquid fertilizers, be careful not to make them too concentrated to avoid root damage. newly potted and repotted plants should not be fertilized too eagerly.
Four: Pest and Disease Control - Address when seen
除春夏两季偶有可见得的黄杨绢野螟外,少有其他虫害.危害症状为局部叶片变黄，发现后只要及时捉除或以敌百虫等普通农药喷施即可.
珍珠黄杨病害发生,参照瓜子黄杨的病害特点,如叶面出现黑色斑点、小枝枯萎等症状,有可能是枝枯病或叶斑病,可用多菌灵、代森猛辛等广普杀菌剂溶液间隔5-7天连续喷洒3-4次。
Five: Pruning - Master the season
