Why don't the flower buds of the black orchid swell? What are the reasons? How do beginners take care of it?
The article brought to you by the editor is about why the flower buds of the black orchid do not swell and its causes, and how beginners take care of it, with related introductions to green plants and flowers. The specific introduction is as follows:
Black orchid, scientific name Cymbidium sinense, is a very popular variety among Chinese orchids, known for its elegant posture and rich fragrance. However, beginners may encounter the problem of non-swelling flower buds in black orchids, which may be related to improper care. Next, let's explore the reasons why the flower buds of black orchids do not swell, and how beginners can correctly care for black orchids.
Reasons for the non-swelling of black orchid flower buds
Insufficient lighting: Although black orchids are semi-shaded plants, they still need moderate sunlight. If they are in a dark environment for a long time, the flower buds may not develop properly, leading to non-swelling. Improper temperature: The optimal growth temperature for black orchids is 15-25°C. High or low temperatures may affect the growth of the flower buds. Especially in winter, if the temperature is too low, the flower buds may stop growing. Improper water management: Black orchids prefer a humid environment but dislike excessive moisture. If overwatered, resulting in waterlogging in the roots, it may affect the growth of the flower buds. Conversely, insufficient water may also prevent proper swelling of the flower buds. Insufficient nutrients: Black orchids require moderate nutrients during growth. If the soil lacks essential nutrients, the flower buds may not develop properly. Diseases and pests: Diseases and pests may also affect the growth of black orchid flower buds. For example, if the roots are invaded by pathogens or eaten by pests, it may lead to non-swelling of the flower buds.
Key points for beginners to care for black orchids
Select the right pot and soil: Black orchids have developed roots and need to choose breathable pots, such as ceramic or plastic pots. For soil, it is recommended to use specialized orchid compost or homemade mixed soil, such as a mixture of leaf mold, perlite, and sand. Lighting management: Black orchids need scattered light and should be protected from direct sunlight. You can place black orchids in a bright area indoors, but avoid direct sunlight. Temperature control: Maintain indoor temperatures between 15-25°C, avoiding high or low temperatures. In winter, pay attention to insulation to prevent low temperatures from affecting the growth of flower buds. Water management: Black orchids prefer a humid but not waterlogged environment. When watering, pay attention to controlling the amount of water to keep the soil moist but not waterlogged. You can adopt the "dry-wet" principle, i.e., water when the soil surface is dry. Fertilization: Black orchids need moderate fertilizers during growth. You can use specialized slow-release fertilizers or liquid fertilizers, fertilizing 1-2 times a month. Avoid over-fertilization to prevent root burn. Pruning: After flowering, black orchids can be pruned moderately to remove weak and dense branches, promoting ventilation and lighting. Disease and pest control: Regularly inspect the leaves and roots of black orchids, and deal with diseases and pests promptly. You can use biological or physical methods for control.
By following these methods, beginners can better care for black orchids, promoting the swelling of flower buds and flowering. At the same time, pay attention to the growth status of black orchids and adjust care measures in a timely manner to ensure the healthy growth of the plants.
