Method of Cultivating White玉兰
Main Content Introduction: This article covers the topic of cultivating White玉兰 at home, including the cultivation methods. Let's find out more in the introduction provided by the editor.
White玉兰, also known as White Orchid or Yellow Angle兰花, is an evergreen tree with a strong fragrance. Its leaves are green, the flowers are white as jade, and they have a fragrance similar to orchids, with a long blooming period. If the environmental conditions are suitable, it can bloom continuously throughout the year. However, it is afraid of drought, waterlogging, cold, and alkaline soil, and is considered a delicate and difficult-to-grow flower in the northern regions. Cultivation requirements:
1. Requires fertile, loose, and well-drained potting soil. A mixture of 5 parts of pine needle decomposed leaves, 2 parts of coarse rice husk ash, 2 parts of coarse sand, and 1 part of matured livestock manure can be used. Avoid using fine sandy soil or heavy clay soil with poor breathability. Use a well-ventilated and breathable earthenware pot (unglazed pot) for potting, avoiding glazed, porcelain, or purple sand pots. It's best to use a deep cylindrical pot, placing an inverted empty pot underneath and elevating it with bricks to prevent poor drainage; place about 5 cm of furnace slag or small stones at the bottom of the pot.
2. Watering should be appropriate. White兰花 has a succulent root system; overly wet potting soil can cause the leaves to turn yellow and fall off, or even rot the roots, while overly dry soil can cause the leaves to wilt and curl. It is a flower that fears both waterlogging and drought. When the petals are excessively open during the blooming period, it indicates insufficient water; when the soil surface is dry and hard, it's time to water immediately. Watering requires that the water and soil temperatures must be consistent, avoiding sudden cold or hot water. Watering must be thorough; frequent half-watering can cause shallow roots. In spring and autumn, watering should not be excessive, in the heat of summer, water every evening, and from late autumn, reduce watering, and in winter, water once every 10 days. During rainy seasons, it should be moved to a sheltered area.
3. It dislikes alkaline soil. White兰花 prefers acidic soil with a pH requirement of 5.5-6.3. In the northern regions, it is difficult to cultivate White兰花 because most of the water and soil there are alkaline, which dissolves the protoplasm in the cells, causing slow growth and poor development of the flowers. Regularly watering with fermented rice washing water has a good effect.
4. It dislikes heavy fertilization. White兰花 likes phosphorus and potassium fertilizers but dislikes high concentrations, which can cause reverse osmosis, leading to "physiological drought" in the plant, causing it to wilt or even die. The principle of fertilizing White兰花 is: "dilute, frequent, and fertilize in the evening." Practice has shown that using a dilute solution of human waste or soybean cake water mixed with crushed fish, rotten shrimp, and chicken innards, composted and applied at a ratio of 1:9, every 3-5 days, with calcium sulfate added during application, has a good effect, making the White兰花 fragrance stronger.
Other tips: Pruning leaves and pinching the growing tip. I cultivate White兰花 from the time of Chunfen to Qingming, choosing overcast or cloudy days for this process. After moving it outside, let the potted plant adapt to the outdoor environment for 2-3 days before removing the old leaves, leaving only a few young leaves on the tips to promote new growth. After each bloom, a small number of old leaves should also be removed to promote new branch growth and bud formation. During the growing period, pinching the growing tip is necessary to control the apical dominance and promote more lateral branches.
Appropriate lighting, White兰花 is a sun-loving flower that requires plenty of sunlight. During the growing period, it should be cared for in a sunny location with long daylight hours and strong sunlight, especially during the blooming period. Daily sunlight should not be less than 6 hours. If it is kept in a shaded area, it will only grow leaves and not bloom, or bloom very few flowers, with thin, pale leaves without luster, which is disadvantageous for growth. However, during the hot and humid "dog days," some shading is needed, avoiding direct sunlight from 12-16 hours and the high-temperature radiation from brick walls or concrete ground. During this time, not only should the plant be sprayed with water to cool down, but the ground should also be watered or sprayed to dissipate heat and increase humidity.
