Until the narcissus in the bedroom was moved to the living room, there was no more itchy throat when I slept at night.

South American narcissus is native to Colombia and Peru, and prefers high temperatures and scattered light environments, is afraid of strong light exposure, and is not cold tolerant. The overwintering temperature should be kept above 16 C. It grows well in loose, fertile and well-drained sandy loam soils.

Potted South American narcissus should choose sandy culture soil rich in humus, and the plants that have just been potted on the ball should be watered less, and the watering amount should be gradually increased after the leaves germinate. If the room temperature can be maintained at 20 25, it can bloom three times a year in winter, spring and autumn. There is a short hibernation after each flowering, which should be kept moderately dry.

In other growing seasons, keep the potting soil moist and apply liquid fertilizer about once every 10 days.

South American narcissus is a medium line of rapid flowers, generally more than 50% of the degree of shelter, in order to grow and develop well. Therefore, it is necessary to shade in summer to prevent strong light exposure, put half light in spring and autumn, and put indoor light in winter in northern areas, and pay attention to ventilation, then the flowers are lush and grow strong. It is best to change the pot once a year in early spring, add new culture soil and increase basal fertilizer when changing the pot to supplement nutrition.

South American narcissus is commonly used for propagation by dividing the chain and seeding. Split-ball propagation is carried out in the spring in conjunction with repotting, and the daughter balls around the cue ball are peeled off and repotted. Propagation with split balls and seeding.

Plants that grow for 2 to 3 years, the aboveground part begins to differentiate flower buds, the pregnant buds bloom, and some small bulbs sprout around the underground bulbs, and these small bulbs can become a complete young plant after a year of vegetative growth.

South American narcissus likes fertilizer and does not choose fertilizer, in order to develop the root system, liquid fertilizer can be applied every other week during the growth period. It is not sensitive to the length of sunlight, but in summer it should be shaded and the potted plants should be placed in a ventilated place indoors.

In winter, it should be fully exposed to sunlight, so that the flowers can flourish and grow vigorously. Aphid damage will occur under high temperature and dry conditions, and it is also susceptible to viral diseases, so attention should be paid to prevention and control.

1. Temperature: The most suitable temperature for the growth of South American narcissus is 25-28, and the temperature should not exceed 30 in summer, otherwise there will be slow growth, and it should not be lower than 15 in winter.

2. Light: It has no requirements for the length of light time, just give enough sunlight. In winter and summer, you need to pay attention to adjusting the light, in summer you need to put it in a scattered place or a weak light place, and you can give it all-day light in winter.

3. Soil: South American narcissus has relatively high requirements for soil, and it is best to prepare soil with more humus content, and the soil mixed with garden soil, humus soil and decomposing base fertilizer is more suitable for its growth.

4. Watering: Its water requirement is very simple, just keep the soil moist. In winter, it is necessary to reduce the frequency of watering, and do not need to be watered during the flowering period.

1. Repotting: It is best to change the pot in early spring, and the temperature gradually warms up to help fix the roots. Don't forget to add some base fertilizer when changing pots, it still has a relatively large demand for fertilizer.

2. Reproduction: There are many ways to reproduce narcissus in South America, among which the more commonly used is split-ball reproduction. This method can be carried out during the spring repotting, break off the small sub-ball next to the cue ball, and find another pot to plant.

1. Pests and diseases: In the summer when the temperature is high and sultry, aphids are easy to appear. At the same time, aphids can also bring a lot of viruses, which can be prevented by weeding and keeping the potting soil clean and hygienic. At the same time, it can also be controlled with 40% dimethoate 1000 times solution.

2. Yellowing: The yellowing of the leaves is mostly caused by sun exposure or low ambient temperature in winter, and remedial measures should be taken in time to take remedial measures in the case of yellow leaves, and the maintenance position should be transferred in time to avoid exposure to the sun, or the maintenance temperature should be increased in winter.

1. Is it toxic: it has a certain toxicity, try not to touch its juice during the breeding process, and wash it with water as soon as possible if it accidentally touches the body.

2. Can it be placed in the bedroom: There is no problem with raising South American narcissus at home, but its bulb is toxic, try not to breed it in the bedroom.

Cultivation method: suitable soil, South American narcissus is suitable for growing in sandy soil rich in humus; Proper light, in spring and autumn it needs to be maintained in a ventilated environment, and in summer it needs to be placed in a cool place indoors; The temperature is suitable, and the indoor breeding of narcissus should ensure that the ambient temperature is around 20 25, and the winter temperature is best above 16. Notes:

The amount and frequency of watering should be reduced when it is just potted, and watering should also be stopped during flowering.
