Why do Cymbidium orchids die?
The internet tells everyone about the knowledge of growing Cymbidium orchids at home. Why do Cymbidium orchids die? Next, the website editor will introduce the topic to netizens.
When Cymbidium orchid seedlings show symptoms like burnt tips, yellow leaves, yellow foot shells, rotten hearts, rotten roots, and rotten pseudobulbs, and eventually the whole plant dies, it causes significant economic losses to investors in high-quality Cymbidium orchids. There are various opinions among orchid enthusiasts, and only when faced with difficulties do they realize the challenges of growing orchids. After investigation and analysis, the main reasons are:
Firstly, excessive fertilizer. The growing medium for Cymbidium orchids should be lean rather than rich. When configuring the medium, do not worry about insufficient fertility and add too much heavy-fertilized material. If the cultivation soil is too fertile, it should be replaced or treated technologically promptly. During the management of Cymbidium orchids, if the plants can grow normally relying on the medium, there is no need for additional fertilization. If fertilization is necessary, use organic fertilizers primarily, and the organic fertilizers must be decomposed before use. Undecomposed grass, bone meal, and oilcake should not be used directly as fertilizer for orchids. Specialized orchid nutrient formulas are also a type of fertilizer and caution must be exercised to avoid overuse, which can cause fertilizer damage. When using organic or chemical fertilizers, they should not be overly concentrated and should be applied frequently but thinly.
Secondly, excessive medication. Any medication has side effects, just like a healthy person who takes medicine every day without illness can develop health problems. Medications used in Cymbidium orchid management can be divided into sterilizing, insecticidal, and hormonal agents. Frequent or excessive use of different medications can cause damage. Prevention is the main strategy, and healthy Cymbidium orchids may not need medication. Only use the appropriate amount when pests or diseases are present. When temperatures rise and humidity decreases, prevent the natural increase in concentration of medications or fertilizers from damaging the seedlings.
Thirdly, excessive temperature. Cymbidium orchids need to grow in a suitable temperature and temperature difference environment. The suitable temperature range for Cymbidium orchid growth is 15 to 30 degrees Celsius, with a day-night temperature difference of 5-15 degrees. When the potting soil temperature exceeds 35 degrees Celsius and the day-night temperature difference is minimal, or when exposed to UV lights for extended periods, the plant conduits that transport nutrients to the orchids are easily mechanically damaged, and the繁殖 speed of viruses and bacteria in the environment is very fast, making it easy for Cymbidium orchids to become infected and die.
Fourthly, excessive humidity. The growing environment for Cymbidium orchids should be dry rather than wet. Do not water too frequently or water overhead during hot and humid seasons to prevent waterlogging, root damage, and heart rot, which can lead to seedling death.
Fifthly, insufficient ventilation. Both the orchid pots and the orchid room need ventilation. The growing medium should be coarse rather than fine. The orchid room should not be stuffy and should be well-ventilated to prevent kitchen or factory fumes from entering, as harmful gases can breed viruses and bacteria, making it easy for orchids to get sick.
Sixthly, too much separation. Cymbidium orchids are clumping plants that prefer to grow in groups. They generally should not be divided too frequently or planted singly. Weak, old, or diseased seedlings that are too isolated have poor disease resistance. Introduce healthy new seedlings without disease, and promptly disinfect and isolate diseased seedlings. Only after normal growth can they be placed in the orchid room to prevent cross-infection. Tissue culture seedlings and greenhouse seedlings have relatively weaker adaptability to natural environments and require careful care. Do not rush to success or force growth.
In summary: Cymbidium orchids are killed by over-fertilization, over-medication, heat, waterlogging, suffocation, over-separation, and even by too much love.
That's all for the knowledge about why Cymbidium orchids die. I hope this article can provide you with some help!
