How to enhance the fragrance of orchids
The website introduces you to the knowledge of orchid plants, how to enhance the fragrance of orchids, and the specific details are as follows:
Orchids in nature exude a delicate fragrance, refreshing the mind and soul, and are known as the "king of fragrances," highly favored by people. For thousands of years, people have adored orchids, and their charm lies in their subtle scent. Without fragrance, orchids are not desirable. Practice has proven that to enhance the fragrance of orchids, attention should be paid to the following issues.
Firstly, the planting material should be rich in nutrients
It is best to use improved orchid soil, which has been used by people for thousands of years to plant orchids. As long as the planting method is correct, the orchids will naturally contain fragrance every year. To better solve the problem of ventilation and drainage of planting materials, modern people have kept pace with the times and created various granular planting materials, which is a significant improvement. Since artificial granular materials generally lack nutrients, people have used modern technology to create various orchid fertilizers to supplement the insufficient nutrients, achieving good results. However, artificial fertilizers cannot fully meet the large amount of trace elements and minerals required for orchid growth. Therefore, using only artificial granular materials and fertilizers to grow orchids will affect the flower quality, especially the subtle fragrance of orchids to varying degrees. Practice has shown that the best way to grow orchids is to combine modern and traditional methods, mixing sieved orchid soil with artificial granular materials to plant orchids, resulting in robust growth, beautiful flower colors, and abundant fragrance.
Secondly, appropriately increase sunlight exposure
Allow orchids to bask in the sun more often. The nutrients needed for orchid bud differentiation and flowering are largely produced through photosynthesis. The longer the sunlight exposure, the more nutrients produced by photosynthesis, and the stronger the fragrance of the flowers. If sunlight is insufficient, although the plant may grow lush, the lack of nutrients produced results in few flowers, and even if they bloom, the fragrance is mediocre. Therefore, increasing sunlight exposure appropriately, and allowing orchids to bask in the sun during spring, autumn, and winter are necessary conditions for orchids to bloom and emit fragrance on time.
Thirdly, strive to create a suitable temperature difference
The growth of orchids is a unity of photosynthesis and respiration. On one hand, during the day, the orchid plant continuously produces nutrients through photosynthesis; on the other hand, the plant constantly consumes nutrients through respiration day and night. The higher the temperature, the more nutrients are consumed, and the lower the temperature, the fewer nutrients are consumed. Only when the nutrients produced by photosynthesis are greater than the nutrients consumed by respiration can orchids bloom and emit fragrance. Therefore, a necessary temperature difference is an indispensable condition for the subtle fragrance of orchids.
Fourthly, orchids need full vernalization
In the wild, the temperature of orchids in winter is generally between 0°C and 15°C. Although the orchid seedlings do not grow, the flower buds continue to grow and accumulate nutrients in preparation for flowering, which is an indispensable stage for orchid flowering. If the temperature in winter is too high and vernalization is not sufficient, orchids may exhibit a僵蕾 (stuck bud) phenomenon, and even if they bloom, the flower quality is poor, and the fragrance is faint.
Fifthly, the potting soil should be moist but not too wet during flowering
When orchids are blooming, the moisture level of the potting soil is also one of the factors that affect the quality of the orchid flowers and their fragrance. Before the flowers bloom, water thoroughly once, and generally do not water after the flowers bloom, as this may affect the fragrance of the orchids. Practice has shown that allowing orchids to bloom slightly dry enhances the fragrance, which is a trick to improve the fragrance of orchids.
