Growth environment of Euphorbia japonica
As a star variety in the succulent plant world, Euphorbia euphorbia is highly sought after for its unique variegated brocade variation characteristics. The growth status of this succulent shrub native to South Africa is closely related to its living environment. In order for it to show the beauty of orange and yellow markings, factors such as light, temperature and humidity must be accurately controlled. The factors of the growth environment of Qiangge Brocade, lighting conditions and placement position, sufficient scattered light is the key to maintaining Qiangge Brocade. It is recommended to place it on the east-facing or south-facing windowsill. In spring and autumn, soft light is guaranteed for 4-6 hours per day, and in summer, strong ultraviolet rays need to be avoided from 11-15 o'clock. Experimental data shows that when the light intensity is below 5000 lux, the area of the new leaf spotted brocade will decrease by 40%. Temperature control and seasonal management 15-25℃ is the best growth range, and controlling the temperature difference between day and night within 8℃ can promote nutrient accumulation. In winter, it is necessary to maintain overwintering temperatures above 8℃. When the environmental temperature is below 5℃ for 72 hours, irreversible damage will occur to the roots. In northern regions, it is recommended to use double insulation films with fill light for winter. Water management and soil allocation adopt the "see dry, see wet" watering method, and the soil is completely dried before watering. Soil matching needs to ensure breathability, and the golden ratio of red jade soil: volcanic rock: leaf soil =5:3:2 is recommended. It is worth noting that when the air humidity exceeds 75% in the plum rainy season, watering needs to be suspended and dehumidification equipment started. Air circulation and disease prevention An air flow rate of 0.5-1m/s per hour can effectively prevent scale insect infestation. It is recommended to install circulating fans in the maintenance space, especially in closed balcony environments, where forced ventilation for more than 4 hours per day is required. Regular spraying of garlic extract can improve plant disease resistance. Key points for daily maintenance of Euphorbia Pavilion brocade apply phosphorus and potassium slow-release fertilizer once a month in spring and autumn, and stop fertilizer and control water during high temperature periods in summer. Pot replacement should be carried out in spring, and a new container 5 cm larger than the original pot should be selected. By observing the color changes of the top growth points, the maintenance plan can be adjusted in time: when the new leaves are greener, the light needs to be enhanced, and when gray patches appear, the root condition needs to be checked.
Mastering the environmental needs of the Euphorbia Pavilion Brocade can not only maintain its strong vitality, but also stimulate the greatest ornamental value of the brocade. By simulating the climate characteristics of the native area and cooperating with scientific monitoring methods, even novices can cultivate amazing brocade plants. Regularly recording changes in environmental parameters and establishing a dedicated maintenance log will significantly improve the success rate of cultivation.
