How to grow a giant crinum lily? Cultivation methods and precautions
The giant crinum lily (Crinum asiaticum) is suited to loose, fertile, well-drained soil. It likes a fairly humid air environment; when the air is dry, you need to spray water around the plant to increase air humidity, and during the growing season water it more to keep the soil moist. The giant crinum lily loves light, and a growing temperature of 18-22°C is most suitable. During the growing period, apply light fertilizer frequently.
1. Soil environment
The giant crinum lily needs plenty of nutrients to grow, so growing it requires loose, fertile, well-drained soil rich in humus. For a homemade mix, you can use leaf mold, coarse sand and garden soil in a 1:1.5:1.5 ratio. It is best to loosen the soil once a month.
2. Water and humidity
The giant crinum lily likes a fairly humid environment. When the weather is dry, it is not enough for the plant to absorb water through its roots alone; at this time you need to spray water around the plant to increase air humidity. During the growing period it needs more watering; just keep the soil moist according to the temperature. In winter, watering must be strictly controlled.
3. Light and temperature
The giant crinum lily has a fairly high demand for light; it is best to let it get more than 4 hours of sun every day, and in summer shade measures should be taken. During the growing period, turn the pot every day to keep the plant from growing lopsided. The giant crinum lily likes a warm climate; conditions of 18-22°C are most favorable for its growth. In winter, keep it warm to avoid cold damage.
4. Fertilizer application
During the growing period, the giant crinum lily should be given light fertilizer frequently. In spring, apply fertilizer mainly of nitrogen; when the plant produces flower buds and during flowering, you can apply phosphorus and potassium fertilizer, which helps the giant crinum lily bloom more and prolongs the flowering period. In autumn, apply decomposed fertilizer. In winter, when the temperature is low, there is no need to apply fertilizer.
