When do green onion orchids bloom? What month is the flowering season of onion orchids?

Onion lotus, also known as Yulian, onion orchid and so on, perennial herb, bulb ovate, about 2.5 cm in diameter, with an obvious neck, neck length 2.5-5 cm. Leaves narrowly linear, fleshy, bright green, 20-30 cm long and 2-4 mm wide. So when do green onion orchids bloom? What month is the flowering season of onion orchids?

According to the understanding of onion orchid growers, the flowering period of onion orchid is between July and September. Green onion orchids bloom from bloom to fall: each flower can bloom for about 2-4 days, and it won't work for 1 day if the sun is exposed to the sun for too long.

Species distribution

Green onion lotus is native to South America and is distributed in warm areas. It has been introduced and cultivated in Central, East, South and Southwest China.

Growth habit

Green onion lotus likes fertile soil, sufficient sunshine, tolerance to semi-shade and low humidity, fertile, sticky and well-drained soil. It is more hardy, can keep evergreen in the Yangtze River basin, and can survive for a long time below 0 °C. Under the condition of-10 °C, it will not be frozen for a short time, but it may freeze to death for a long time. Onion lotus is easy to divide balls naturally, and it is easy to propagate in separate plants. in order to cultivate it, we should pay attention to the proper protection against cold in winter.

Cultivation techniques

Field management

Temperature

Onion lotus likes a warm climate, but the environment of high temperature and muggy summer (more than 35 ℃, air relative humidity more than 80%) is not conducive to its growth; it is very strict on winter temperature, when the ambient temperature is below 10 ℃, it can not safely survive the winter when the frost occurs.

Water and fertilizer

Onion lotus likes plenty of sunshine, but it can also withstand semi-shade and requires a warm and moist environment, which is suitable for sandy loam rich in humus and good drainage. When cutting the land, we should apply enough base fertilizer, keep the soil moist during the growth period, and apply thin cake fertilizer and water 2-3 times a year, which can grow well and bloom luxuriantly. When cutting the basin, the basin soil should be loose, fertile and drained. It can be mixed with rotten leaf soil or peat soil, garden soil and river sand. Watering during the growth period should be adequate, it is appropriate to keep the basin soil moist, but not stagnant water. When the weather is dry, water is often sprayed on the leaves to increase air humidity, otherwise the leaf tips are easy to yellow and wither. In the vigorous growing season, rarefied liquid fertilizer should be applied every half a month.

Pest control

Green onion lotus is mainly damaged by insect pests, such as onion orchid night moth, mainly harmful to green onion lotus, Zhu Dinghong, Lycoris and other plants, is a secondary pest. Spodoptera litura can eat up all the aboveground stems of onion lotus when it is serious. Although the stems and leaves of onion lotus were fed by the insect, the aboveground part could still germinate and grow, which did not cause the death of onion lotus, but its growth potential was obviously weakened.

Prevention and cure method

Turn the ground in winter or early spring, dig out the overwintering pupae and reduce the population number; when the larvae occur, spray 1500 times of rice, 1500 times of Lesbon or 800times of phoxim EC, and choose to spray when the larvae come out in the morning or evening. The control effect is better.
