Reasons Why Orchids Fail to Bloom
Let's talk about the related topics of orchids, a member of the orchid family. The reasons why orchids fail to bloom are as follows:
It is often heard that some orchid enthusiasts have been growing orchids for several years without them blooming, not knowing the reasons why orchids fail to bloom. Generally speaking, a normal adult orchid plant, as long as it has reached a cluster of two to three seedlings, can bloom under proper cultivation conditions (a少数 of orchids can bloom with a single seedling, such as the cold orchid with thick roots and thin leaves). The reasons are roughly as follows:
First, even if seedlings and tissue-cultured seedlings are cultivated for many years, they may not necessarily bloom. Just like other plants, for example, fruit trees need to reach a certain age before they can bloom and bear fruit. Orchids also need to reach a certain age before they can bloom and produce seeds.
Second, the species differences among various orchids and the varying climatic conditions in different regions can make it difficult for orchids to bloom, which is a common phenomenon. Take春兰 (spring orchid) for example; it is difficult to bloom in some regions, or there are fewer that bloom. For instance, in Hainan or southern Guangdong, where the temperature is relatively higher and more balanced compared to other parts of the country, even if the spring orchid has flower buds, it cannot bloom due to the lack of normal spring flowering conditions (cold training). There are also other orchid species where the difference in latitude between the north and south leads to non-blooming or abnormal blooming. For example, some wild orchid species are extremely sensitive to climate and no longer bloom in regions with significant climatic differences. However, such orchid species are rare. In the national orchids, 春兰, 建兰, 蕙兰, 春剑, 连瓣, 墨兰, and 寒兰 can bloom in most provinces of the country. Moreover, it is now possible to use air conditioners and solar greenhouses to control the temperature to promote orchid growth and blooming.
Third, the physiological growth of orchids is disrupted for various reasons, and new leaf buds suddenly appear during the formation of flower buds. In this case, the orchid plant does not have more nutrients to maintain the normal differentiation of flower buds, resulting in the cessation of flower bud growth and failure to bloom.
Fourth, improper cultivation methods may also lead to orchids not blooming. Here are a few situations: 1. The planting material for orchids contains too much nitrogen fertilizer and too little phosphorus and potassium fertilizer, leading to excessive vegetative growth and suppressed reproductive growth. It is similar to the fruit trees planted in front of houses and backyards by farmers, which due to the overly fertile soil and frequent addition of garbage and livestock manure, only grow leaves and do not bloom or bear fruit. The solution is to replace the planting material with a balanced nutrient mix or to increase the application of phosphorus and potassium fertilizers. 2. Excessive watering during the flower bud differentiation stage, with the planting material being too wet, can also lead to excessive vegetative growth and suppress reproductive growth. 3. Insufficient lighting is also one of the reasons why orchids fail to bloom. Although orchids are shade-loving plants, they still need some sunlight to maintain normal physiological activities.
Solutions include allowing orchids that do not receive sunlight to enjoy as much sunlight as possible (but not direct exposure), especially the warm and gentle morning sunlight. Besides sunlight, the accumulation of photosynthetic products (organic matter) also relies on day-night temperature differences. In regions where there is little day-night temperature difference and orchids often fail to bloom, it is necessary to create day-night temperature differences artificially.
Fifth, there is also the special reason of the orchid itself that prevents blooming, or that a few orchids do not like to bloom. This phenomenon has appeared in various orchid species, and I have encountered it personally: in 2004, a simple sprout of Jianlan was collected from the mountains in this area. It has been cultivated in our garden for six or seven years and has developed into more than ten pots, but it has never bloomed to this day. This might be the infertility or sterility phenomenon in plants (orchids).
