What are the methods and precautions for growing Phalaenopsis orchids
The article discusses the methods and precautions for growing Phalaenopsis orchids and the correct approach for beginners in plant care. Let's continue with the introduction by our site editor.
Phalaenopsis orchids, also known as Moth orchids, belong to the Orchidaceae family, Phalaenopsis genus. They are a popular orchid species for home potted cultivation, thriving in warm, humid, and semi-shaded environments. They are intolerant to cold, dry air, and wind. The optimal growth temperature is between 14-24 degrees Celsius, with a recommended relative humidity of 60%-80%; a shading rate of 60%-70% is most suitable.

Phalaenopsis orchids are the guardian flower of Sagittarius and the lucky flower of Leo. They are suitable for giving to girlfriends on Valentine's Day, symbolizing "purity and beauty."
So, how should potted Phalaenopsis orchids be cultivated, and what precautions should be taken? Let's briefly discuss the methods for growing Phalaenopsis orchid pots.
For Phalaenopsis orchids, remember these 5 points for successful growth and blooming!
One, Buying Guide
For beginners, it is recommended to choose white or red Phalaenopsis orchids. Opt for plants that have started blooming, with intact petals and bright colors. For those purchasing flowering branches, it's best to choose branches 3-4 days after the buds have opened and promptly transfer them to hydroponic culture.
Two, Pot and Soil Selection
For potted Phalaenopsis orchids, a shallow pot with a diameter of 20-30 centimeters is ideal. The soil should be loose, well-draining, and breathable. Common soil mixtures include: humus, peat, coal cinders, charred soil, a mixture of coarse sand and wood ash, and you can also place orchid stones or moss on top of the soil. The best time to repot Phalaenopsis orchids is in late May. They require well-aerated, decomposable, slightly acidic soil. You can use a mixture of pine needles, peanut shells, bark fibers, and clay balls as a soil matrix, or purchase special Phalaenopsis orchid soil from the flower market.
Three, Seasonal Watering and Maintenance
In spring, when Phalaenopsis orchids are in full bloom, water them every 2-3 days, keeping the soil moist. In summer, when temperatures exceed 20 degrees Celsius, move them indoors to avoid direct sunlight and place them in a location with diffused light. Water them once a day, and during hot, dry weather, spray their leaves to increase humidity. In autumn, water every 2-3 days, preferably not at night. In winter, move them to a warm indoor area, maintaining a temperature of 12-15 degrees Celsius for blooming. If the temperature drops below 10 degrees Celsius, they are prone to frostbite and disease.

Four, Fertilization Method
To ensure that Phalaenopsis orchids grow well and bloom to fill the pot, fertilization is a crucial step! In late May, for Phalaenopsis orchids that have just been repotted, they are in the root recovery stage and should not be fertilized. From June to September, during the growth period of new roots and leaves, fertilize once a week. During high summer temperatures, fertilization can be paused for 2-3 times. After October, as the growth of the plant slows down, reduce the amount of fertilizer to avoid excessive growth, which can affect the formation of flower buds and prevent blooming. In winter and during the blooming period, fertilization should be stopped to prevent root rot.
Five, Pruning and Propagation Methods
After the Phalaenopsis orchid flowers have completely wilted,剪除 the flower spike entirely to avoid excessive nutrient consumption. The propagation method by division: when the roots of the potted Phalaenopsis orchid grow out of the pot and the axillary buds on the flower spike develop into new plants with new roots, they can be separated from the mother plant with a knife and planted separately. It is best to divide after the flowers have completely wilted, often combining division with repotting in late spring and early summer.
Six, Precautions
1. Some people, worried about their Phalaenopsis orchids lacking water, water them every day regardless of whether the growing medium is dry, leading to severe root rot. Although water is the source of life, being constantly soaked in water can cause swelling!
2. Some people apply fertilizer whenever they have it, without paying attention to the concentration, believing that more fertilizer means faster growth. Remember, Phalaenopsis orchids prefer light fertilization and should be fertilized in small amounts multiple times. Avoid over-fertilizing as it can be counterproductive.
3. Some people think that using a large pot can provide a spacious environment and sufficient materials for Phalaenopsis orchids. However, a large pot makes it harder for the soil to dry out, and Phalaenopsis orchids prefer well-ventilated conditions.
