What are the precautions for growing Phalaenopsis orchids?
1. Some friends always worry that their Phalaenopsis is short of water, so they water it every day no matter whether the growing medium is dry or not, causing severe root rot. Although water is the source of life, staying soaked in water all day will still make it swell up!
2. Some friends apply fertilizer whenever they have some, and pay no attention to the concentration, thinking that fertilizing will make the plant grow faster. You should know that Phalaenopsis should be given dilute fertilizer, applied little and often. Remember that "tonic feeding" must not be excessive, otherwise it will backfire.
3. Some friends think that using a large pot can give the Phalaenopsis a spacious environment and plenty of material. In fact, after using a large pot, the sphagnum moss does not dry out easily. You should know that Phalaenopsis likes good ventilation, and with free airflow it thrives.
Having introduced the growing methods and precautions for Phalaenopsis, let us look at the value and uses of Phalaenopsis.
How to grow Phalaenopsis: precautions for growing Phalaenopsis
Growing some flowers and plants at home is a hobby of many friends. Many delicate little flowers make life full of hope. Phalaenopsis is one of the most popular potted plants in our daily lives. Its flowers are graceful in form and gorgeous in color, and it has the reputation of being the "queen of orchids". However, many people are not very familiar with the growing methods and precautions for Phalaenopsis. Below, we will explain the growing methods and precautions for Phalaenopsis, hoping to help everyone.
Introduction to Phalaenopsis
Phalaenopsis likes a high-temperature, high-humidity, well-ventilated environment; it is not tolerant of waterlogging, tolerates semi-shade, and dislikes direct blazing sun and standing water; it fears cold. The optimum growing temperature is 22-28°C, and the overwintering temperature should not be lower than 15°C. Phalaenopsis is a tropical plant, and the cultivation temperature should be maintained between 15-34°C. At different growth stages, the required temperature also differs.
The growing stage is 26-27°C, and the flowering stage is 19-21°C. To obtain more flower spikes, the temperature can be maintained at 18-20°C for a total of 4-8 weeks. When light is insufficient or the day temperature is too high, maintain 18°C to strengthen flower forcing (inducing flower buds). Because leaf growth must also be maintained during the flowering period, do not keep the low-temperature period too long. When light is insufficient, if the temperature is above 23°C for more than 24 hours, it will cause excessive vegetative growth and the loss of flower buds.
Growing methods for Phalaenopsis
1. There is a natural sowing method, which is to sow the seeds released from already split seed capsules into the pot of the parent plant. This method is simple and easy, requiring no complicated sterile procedures or operating tools, and is suitable for ordinary home Phalaenopsis growers, but the chance of success with this method is very small, so it is rarely used.
2. There is also a sterile sowing method. This method first washes the unopened mature seed capsules, then soaks them in 75%-90% ethanol or chloroform for 2-3 seconds, and then soaks them in a 5%-10% bleaching powder solution or 3% hydrogen peroxide for 5-20 minutes. Take out the seeds and soak them in the same disinfectant solution for 5-20 minutes, then remove the solution by filtering, take out the seeds, and use a fine needle to spread the seeds evenly on the surface of the prepared culture medium in a bottle.
The culture conditions are a light intensity of 2000-3000 lux, 10-18 hours per day, with the temperature kept at 20-26°C. After 9-10 months, when the small seedlings have grown 2-3 leaves, they can be taken out of the bottle and planted in pots.
For cultivating Phalaenopsis, sphagnum moss and moss are generally chosen as the growing medium. The principle of fertilizing should be to apply less fertilizer and dilute fertilizer. During normal growth, apply orchid-specific fertilizer at 2000 times dilution as a root fertilizer; depending on the growth situation, once every 2-3 weeks. Before flowering, a 15-30-15 water-soluble high-phosphorus fertilizer at 1000-2000 times dilution can be used, sprayed about once every 10 days; stop fertilizing during the flowering period and in seasons with lower temperatures.
Precautions for growing Phalaenopsis
1. First, it must get through the summer smoothly. If possible, place it in a spot with bright light but not direct sunlight; reduce water supply (although summer temperatures are high, excessive water can easily cause root rot and lead to plant death); if you feel you do not know how to fertilize, you can keep using clean water, especially in summer, and try not to fertilize or fertilize less; after summer, to be safe, you can check the root system and growing medium again to ensure the basic elements for normal plant growth.
2. Temperature: not lower than 15°C at night, and not lower than 18-20°C during the day; a larger temperature difference is better. Air humidity: higher air humidity is better, but in home cultivation air humidity is very hard to regulate, so let the plant slowly adapt. At first you can mist the leaves every day, but the amount should not be too large; just moistening the leaves is enough.
3. Usually pay attention to observing the root growth. Living roots are the basic element for maintaining plant growth. If the root color is green, robust, and firm, and the root tips are red, it shows vigorous vitality; if you find roots escaping from the pot, it indicates a problem with the growing medium or care, and adjustment is needed; if the roots turn black and rot, it indicates too much water; if some roots show symptoms of drying up, it indicates excessive water shortage.
In a normal state, Phalaenopsis leaves are bright, glossy, thick and firm, showing good growth, and new shoots will keep emerging.
The above is the explanation of the growing methods and precautions for Phalaenopsis. Is everyone clear now? For more home decoration knowledge, please stay tuned.
Growing methods for Phalaenopsis: precautions for growing Phalaenopsis
Phalaenopsis is a beautiful flower. Many people like to keep a pot of Phalaenopsis at home; it looks very elegant and brings a good mood. But Phalaenopsis is also a rather delicate flower. So here are the growing methods for Phalaenopsis and the precautions for growing Phalaenopsis.
Growing methods for Phalaenopsis:
1. Temperature:
When growing Phalaenopsis at home, the first thing to ensure is temperature. Phalaenopsis likes a high-temperature, high-humidity environment. During the growing period, the minimum temperature should be kept above 15°C, and the suitable growing temperature for Phalaenopsis is 16-30°C. In autumn and winter, at the turn of winter and spring, and when winter temperatures are low, attention should be paid to raising the temperature. Generally, in rooms with heating equipment in winter, this temperature is not difficult to reach, but note that the flower should not be placed directly on the radiator or too close to it. When summer temperatures are on the high side, cooling is needed, and attention should be paid to ventilation. If the temperature is higher than 32°C, Phalaenopsis usually enters a semi-dormant state, and continuous high temperatures should be avoided. Around the Spring Festival is the full flowering period; appropriately lowering the temperature can prolong the viewing time. During flowering, the nighttime temperature is best controlled between 13-16°C, but it must not be lower than 13°C.
2. Humidity: Phalaenopsis originates from primitive forests, where there is more mist and higher temperatures. Phalaenopsis has no thick pseudobulbs to store nutrients, so if the air humidity is insufficient, the leaves will wrinkle and become weak and limp. Therefore, Phalaenopsis should be cultivated and cared for in a ventilated, high-humidity environment. The suitable air humidity for growing Phalaenopsis is 60%-80%. During the vigorous elongation period of new roots, water more; during the dormant period after flowering, water less. In spring and autumn, water once every day around 5 p.m.; in summer, when the plant grows vigorously, water once each at 9 a.m. and 5 p.m.; in winter, when light is weak and temperatures are low, watering once every other week is enough, and it is best done before 10 a.m. If a cold wave strikes, it is not suitable to water; keep it dry, and resume watering after the cold wave passes.
3. Light: Although Phalaenopsis prefers shade, the plant still needs to receive some light, especially before and after flowering. Appropriate light can promote flowering in Phalaenopsis and make the flowers more colorful and long-lasting. Generally, it should be placed in a spot indoors with diffused light, and direct sunlight should be avoided.
4. Ventilation: The normal growth of Phalaenopsis requires flowing fresh air, so home-grown Phalaenopsis must have good ventilation, especially during the high-humidity period in summer. Good ventilation must be used to prevent heat stress, and it can also avoid infection by pests and diseases.
5. Fertilizing: Phalaenopsis should be fertilized throughout the year, and unless low temperatures persist for a long time, fertilizing should not be stopped. Winter is the flower bud differentiation period for Phalaenopsis, and stopping fertilizer can easily lead to no flowers or few flowers. Spring and summer are the growing period, and a dilute liquid fertilizer can be applied once every 7-10 days. Organic fertilizer is preferable, and Phalaenopsis-specific nutrient solution can also be applied, but do not apply it when there are flower buds, otherwise the buds may easily drop early. In summer, when leaves grow (that is, after the flowering period), nitrogen fertilizer and potassium fertilizer can be applied as a top dressing. In autumn and winter, during the flower stem growth period, phosphorus fertilizer can be used, but it should be dilute, applied about once every 2-3 weeks.
6. Pruning: The flowering period of Phalaenopsis is generally around the Spring Festival, and the viewing period can last as long as 2-3 months. When the flowers wither, the faded flowers must be cut off as early as possible, which can reduce nutrient consumption. If the flower stem is cut at the 4th-5th node from the base, it can bloom again after 2-3 months. But this consumes too many nutrients from the plant and is not conducive to growth the following year. If you want it to bloom well again the next year, it is best to cut the flower stem from the base. When the medium ages, it should be replaced in good time, otherwise the air permeability will worsen, causing root rot and weakening the plant's growth or even death. Generally, it is suitable to repot in May when new leaves grow.
Precautions for growing Phalaenopsis:
1. Watering too frequently: Friends who cultivate Phalaenopsis always worry that the Phalaenopsis is short of water, so they water it every day no matter whether the growing medium is dry or not, causing severe root rot.
2. Temperature too low: Usually, flowering Phalaenopsis plants are mostly marketed in early spring, and after being bought home they are generally placed in places such as the living room for viewing. Although the daytime temperature in these places is sufficient, the nighttime temperature is slightly on the low side. On the other hand, professionally cultivated orchids are mostly kept in well-equipped greenhouses. By comparison, the temperature and humidity at home are somewhat insufficient, making the plant's growth increasingly weak. Therefore, sometimes no matter how well it is cared for, the orchid still fails to bloom.
3. Excessive fertilizing: Applying fertilizer whenever you have some, and not paying attention to the concentration, thinking that fertilizing will make it grow faster. You should know that Phalaenopsis should be given dilute fertilizer, applied little and often. Remember that "tonic feeding" must not be excessive, otherwise it will backfire.
4. Planting a small plant in a large pot: Thinking that using a large pot can give the Phalaenopsis a spacious environment and plenty of material. In fact, after using a large pot, the sphagnum moss does not dry out easily. You should know that Phalaenopsis likes good ventilation, and with free airflow it thrives.
5. Dry buds on flowers: Most Phalaenopsis on the market now have been forced into bloom, and after leaving the base, once the environment changes, dry bud problems easily appear. At this time, do not think it is dryness and do not water more; instead, increase indoor humidity and control indoor temperature, which must not be too high. When buying flowers, try to choose ones with thick petals.
6. Common diseases: Phalaenopsis is prone to soft rot and gray leaf spot. Soft rot is extremely contagious; once discovered, immediately isolate the diseased plant. The diseased plant can be treated with mancozeb or copper-based fungicides, generally sterilizing once every 15 days. The common growing media for Phalaenopsis are mainly sphagnum moss and moss, so the potting material should not use soil; instead, use sphagnum moss, pumice, tree fern crumbs, charcoal fragments, and so on.
