Have you ever thought about having a Phalaenopsis orchid at home? It's as beautiful as a little princess! The name "Phalaenopsis" itself is delightful. Its dancing petals seem like the embodiment of a butterfly, making you want to get close. So, how do you grow a Phalaenopsis orchid? Don't worry, let me take you step by step into the world of Phalaenopsis orchids and unveil the mystery of their cultivation.
I. The Home of the Phalaenopsis Orchid
First, you need to find a cozy home for your Phalaenopsis orchid. This isn't as simple as just grabbing any pot! Phalaenopsis orchids prefer soil that is well-ventilated and has good drainage. You can choose materials like pine needles, peanut shells, tree bark shreds, or clay balls, or you can go directly to the flower market to buy specialized orchid soil. Remember, the soil should be loose, not too hard, so the orchid's roots can breathe smoothly.
II. Light and Temperature
The Phalaenopsis orchid is a bit of a lazy creature; it likes cool, shady places but cannot be completely without light. Therefore, you can find a place indoors with plenty of diffused light, like a windowsill, but remember to use a window screen to block some of the sunlight to avoid direct sun exposure. As for temperature, Phalaenopsis orchids prefer a warm environment. The minimum temperature during the growing period should be kept above 15°C, and the suitable growing temperature is between 16°C and 30°C. During the transition from autumn to winter and winter to spring, as well as in winter when temperatures are low, be sure to keep it warm.
III. Watering and Fertilizing
The Phalaenopsis orchid is a bit delicate; it likes a moist environment but fears waterlogging. Therefore, when watering, you should follow the principle of "watering when dry, stopping when moist," meaning don't let the soil get too dry, but also don't let it get waterlogged. During the orchid's growth period, frequent lack of water will cause the leaves to turn yellow, which is difficult to recover from. As for fertilizing, the principle for Phalaenopsis orchids is to use less fertilizer and apply it lightly. You can use foliar fertilizer, potassium dihydrogen phosphate, fermented farm manure diluted with water, or specialized orchid fertilizer. During the growing period, you can alternate between foliar fertilizer and potassium dihydrogen phosphate.
IV. Ventilation and RepottingThe normal growth of a Phalaenopsis orchid requires flowing fresh air, so good ventilation is essential. Especially during the high humidity of summer, good ventilation is necessary to prevent heatstroke and also to avoid pest and disease infections. Additionally, a Phalaenopsis orchid must be repotted once a year. The best time for repotting is late spring to early summer. Timely repotting can prevent poor growth caused by substrate decay, as Phalaenopsis orchids prefer soil with strong aeration.
V. Propagation and MaintenanceThe main method of propagating Phalaenopsis orchids is sowing, but this requires certain techniques and is rarely done at home. Phalaenopsis orchids do not use soil as a medium, but rather sphagnum moss. It must be disinfected before use to ensure the healthy growth of the orchid. As for maintenance, in addition to the points mentioned above, you should also pay attention to the following:
1. The roots of a Phalaenopsis orchid are fleshy and are prone to mold rot. Once symptoms of rot appear, you must clean the roots and soak them in potassium permanganate for disinfection. Treat it promptly, otherwise, it will lead to the death of the plant.
2. A Phalaenopsis orchid can bloom after two years of growth. When it has finished flowering, you need to use a support to fix it, otherwise, it will become top-heavy. The flower spike of a Phalaenopsis orchid is very long, and we can use iron wire to shape it into beautiful artistic creations.
3. During the flowering period, the Phalaenopsis orchid needs more light and can be placed on a south-facing balcony.
4. What to do if the Phalaenopsis orchid's leaves turn yellow and fall off? This may be caused by reasons such as waterlogging, over-fertilization, or long-term lack of water. Take corresponding measures for different causes, such as controlling watering, stopping fertilization, or watering moderately.
5. How should you water and fertilize a Phalaenopsis orchid when it's about to bloom? Phalaenopsis orchids like moisture but avoid waterlogging. They cannot lack water during the growing period. Orchids grown with pine needles will not waterlog. When watering, use a watering can to spray water until it flows out from the bottom of the pot. Often spray water around the orchid pot to keep the air moist, but do not let water accumulate in the center of the leaves, especially at night in winter, do not spray water on the leaves. As for fertilizing, you should apply light fertilizer frequently. In May, the orchid has just been repotted and is in a recovery period, so do not fertilize. From June to September, it is the growing period of the orchid, fertilize once a week, alternating between foliar fertilizer and potassium dihydrogen phosphate. You can also use fermented farm manure diluted with water to irrigate. If conditions permit, you can buy specialized orchid fertilizer and "Hua Bao" liquid fertilizer, dilute 2000 times, and spray on the leaves and cultivation substrate. Stop fertilizing during high summer temperatures. In late autumn, the orchid's growth slows down, so reduce fertilization. Over-fertilization often causes the orchid to grow too vigorously, affecting flower bud formation and leading to no flowering.
6. Home cultivation method for Phalaenopsis orchids: In terms of soil, when cultivating Phalaenopsis orchids at home, you can choose soil that is breathable, contains humus, and is slightly acidic. In terms of watering, during the growing period, the Phalaenopsis orchid needs to be watered twice a week to keep the soil moist. Normally, you should also spray water around the plant to maintain humidity, and pay attention to indoor ventilation. When the weather is warm, you need to move the Phalaenopsis orchid outdoors to get more sun. If the temperature is above 25°C, you must...
