Detailed Explanation of the Planting Methods and Techniques for the Tuberous Sword Fern
The tuberous sword fern (Nephrolepis cordifolia) is a terrestrial herbaceous plant in the family Nephrolepidaceae, widely distributed in China, with high ornamental value in its appearance. Its tubers are also rich in starch and can be eaten. It is also a very traditional Chinese medicinal herb, mainly used to treat common minor ailments such as colds and coughs. So how should the tuberous sword fern be planted? Below, the editor brings you the planting techniques for the tuberous sword fern. Let's take a look!
1. Soil Selection
The roots of the tuberous sword fern do not spread deep, its nutrient absorption capacity is relatively weak, and it also has a certain epiphytic nature. Therefore, before planting, we should choose soft soil that is rich in fertility and has normal drainage and irrigation. Keep the soil rich in humus and high in nutrients, and do a good job of land preparation to improve soil quality, which is more conducive to the growth of the tuberous sword fern. And after land preparation, apply sufficient base fertilizer. Although the tuberous sword fern has strong growth ability, in a suitable environment, sufficient nutrients can effectively increase the yield of the tuberous sword fern, which is very beneficial to its growth.
2. Temperature Control
The tuberous sword fern is not suitable for growing in low-temperature environments, so in winter, attention should be paid to cold protection and heat preservation, and the temperature should not be lower than 5°C. At around 10°C, the tuberous sword fern can grow normally. However, the temperature should not be too high either. If the temperature is too high, it will cause the tuberous sword fern to grow excessively, which not only affects the growth of the underground tubers but also reduces its ornamental value. Therefore, in summer, we should also pay attention to heatstroke prevention and cooling, strengthen ventilation, shorten the watering frequency, and improve the ornamental value. By controlling the temperature at around 32°C, the tuberous sword fern can grow normally.
3. Adjusting Light
The tuberous sword fern has strong shade tolerance and can generally grow normally under scattered light. Moreover, if the light is too strong, it will have a certain impact on the growth of the tuberous sword fern, for example, causing its leaves to turn yellow and fall, and in severe cases, even death. If it has been under scattered light for a long time, do not let it suddenly receive direct sunlight, otherwise it will cause leaf moisture loss, wilting and yellowing, and a serious decline in ornamental value. And we should also provide appropriate light and ensure regular exposure to light, so as to maintain a long-term good ornamental effect of the tuberous sword fern.
4. Reasonable Fertilization
The tuberous sword fern is a fern without flowers or fruits, so its nutrient requirements are not great. However, during the planting process, attention should still be paid to fertilization. The nutrient requirement of the tuberous sword fern is mainly nitrogen fertilizer. In spring and autumn, during the peak growth period of the tuberous sword fern, fertilize about twice a month, mainly with nitrogen fertilizer. But pay attention to the concentration; it should not be too strong, otherwise it is easy to cause fertilizer damage to the tuberous sword fern. Reasonable fertilization can maintain the glossiness of the tuberous sword fern leaves and improve the growth ability of the plant. If fertilized excessively, on the contrary, it will cause the tuberous sword fern to grow weakly and develop undesirable phenomena such as excessive growth.
The above is a brief introduction to how to plant the tuberous sword fern. In fact, these are also the management aspects that we need to pay special attention to during the planting process. Planting the tuberous sword fern is very simple, but the management methods should also be controlled according to the planting direction to ensure normal growth.
