What are the benefits of growing camellia in the field
Camellia is a traditional and precious flower, and its cultivation method directly affects its growth status and ornamental value. Due to its unique advantages, the ground planting model has become a planting method respected by professional gardeners. This article will deeply analyze the five core advantages of planting camellia locally and help you create a flowery camellia landscape. The main root of Camellia japonica can be as deep as 1.5 meters, and the ground planting space allows the root group to form a natural nutrient network. Comparative experiments show that the root volume of ground planted camellia is 3-5 times that of potted plants, and a pot with a diameter of 30cm can only accommodate the growth needs of the plants for 3-5 years. Adequate underground space ensures a 40% increase in oxygen exchange rate and effectively prevents the occurrence of root rot. Soil environment optimization The cultivated soil has a self-regulating function, automatically draining water in the rainy season and replenishing water through capillary phenomena in the dry season. It is recommended to mix 30% humus soil to improve the substrate during planting and maintain the pH value within the optimal range of 5.5-6.5. Water and fertilizer management Scientific land planting can use drip irrigation systems to accurately control humidity, reducing the watering frequency by 50% compared with potted plants. The "three-period method" for fertilization is recommended: apply nitrogen fertilizer to promote new buds in spring, supplement phosphorus and potassium to protect flower buds in summer, and add organic fertilizer in autumn. The annual fertilization amount of locally planted camellia is 30% less than that of potted camellia, but it can increase the flowering amount by 20%. Ecological and environmentally appropriate open-air cultivation allows camellia to obtain a 270° lighting surface, and the average daily light duration is increased by 2 hours. It is recommended to configure deciduous trees as natural sunshade, and the best shade rate in summer is 60%. The air circulation speed in the ground-growing environment is three times that of indoors, effectively reducing the incidence of pests and diseases such as red spiders. Possibility of landscape shaping Planting camellia can form a visual focus with a crown width of 3-5 meters, and the annual flowering volume of a single plant can reach more than 500 flowers. During garden application, camellia and rhododendrons can be combined to create a three-dimensional flower landscape, or pruned into hedges to form spatial divisions. The double-petal variety "Eighteen Scholar" is specially recommended as the main landscape tree, with a flowering period of 120 days.
Through scientific local planting management, camellia can not only show the best growth state, but also become the soul element of the courtyard landscape. It is recommended to select suitable varieties based on the local climate and conduct regular soil testing to give this traditional famous flower new vitality.
