To make the white orchid tree grow thicker, the following comprehensive management measures can be taken: 1. Soil management
Soil selection: White orchids are suitable for growing in slightly acidic soil, with a pH value between 5, 5, 6, and 3. You can choose fertile, loose, and well drained sandy soil for planting.
Soil improvement: If the soil does not meet the requirements, improvement can be carried out. For example, adding an appropriate amount of pine needle rot soil, coarse bran ash, coarse sand, and composted manure to the soil can improve its fertility and permeability. 2、 Light management
Adequate sunlight: White orchids are positive flowers and require sufficient sunlight. During the growth period, the white orchid tree should be placed in a sunny area with long and strong sunlight for maintenance, ensuring that the daily light exposure time is not less than 6 hours.
Avoid direct sunlight: Although white orchids require sufficient sunlight, they also need to be appropriately shaded in the summer when the sunlight is too strong to prevent the leaves from being burned. 3、 Temperature management
Suitable temperature: White orchids prefer warmth and are afraid of cold. The optimal temperature for growth is between 15 and 28 degrees Celsius. In winter, white orchid trees should be moved indoors and placed in a sunny area. It is best to keep the room temperature above 10 degrees Celsius and not below 5 degrees Celsius. 4、 Water management
Reasonable watering: White orchid trees are afraid of both waterlogging and drought, so watering should be done in moderation. When the surface of the potting soil is dry and the soil is hard and cracked, watering should be immediately carried out. The water temperature and soil temperature must be consistent, and cold or hot water should not be poured suddenly. Watering once a day is generally sufficient in spring and autumn, and the frequency and amount of watering can be increased appropriately in summer. Watering should be controlled in winter.
Maintain humidity: It is best to keep the relative humidity of the air between 60% and 80%. When it is below 50%, the leaves will show yellowing, shedding and other phenomena. It is necessary to regularly spray water or water to increase humidity. 5、 Fertilization management
Reasonable fertilization: White orchids prefer fertilizer, but excessive fertilizer can cause fertilizer damage. Fertilization should be done in moderation and at the right time. Before the new shoots sprout from February to March, composted cake fertilizer can be applied as a base fertilizer; During the growth period, thin liquid fertilizer can be applied every 7-10 days; Before spring and autumn flowering, a quick acting phosphate fertilizer should be applied once to promote flower bud growth.
Fertilizer selection: You can choose humus fertilizer, human manure, cow manure, and chemical fertilizers as fertilizers. But the amount of fertilizer application should be strictly controlled to avoid excessive fertilizer damage. 6、 Pruning management
Timely pruning: During the growth process of white orchid trees, the plants should be shaped and pruned. Cut off diseased dead branches and overgrown branches, remove some lower leaves to suppress plant growth and promote more flowering of pregnant buds.
Pruning time: It is best to choose pruning time in spring or autumn, when the temperature is suitable, which is conducive to wound healing and the growth of new branches. 7、 Disease and pest control
Prevention and control of diseases: The main diseases of white orchids include yellowing and anthracnose. You can use 50% carbendazim wettable powder 500 times liquid or 50% tobramycin wettable powder 500 times liquid for spraying and control.
Pest control: The main pests of white orchids include red spider mites, scale insects, etc. You can use a 1000 fold dilution of 20% trichlorfon or a 1000 fold dilution of 50% triphosphon for spraying and control. At the same time, manual capture methods can also be used for prevention and control.
Through the implementation of the above comprehensive management measures, the growth and development of white orchid trees can be effectively promoted, gradually becoming thicker and maintaining a good growth state.
