Narcissus cultivation and care techniques
This article provides you with detailed knowledge about growing narcissus at home, including narcissus cultivation and care techniques. Here is a comprehensive introduction to follow.
Narcissus is also known as narcissus, trumpet narcissus, belonging to the Amaryllis family, Narcissus genus. As a temperate bulbous flower, narcissus prefers cool climates and dislikes high temperatures and humidity. The optimal growth temperature is between 10-15°C. In southern China, it is not easy to cultivate flowering bulbs, so bulbs are imported from abroad every year, cultivated for a short period to bloom, and then discarded after flowering. New bulbs are purchased for cultivation the following year.
When purchasing bulbs, check if they have been cold-stored. If the bulbs have not been cold-stored, they should be placed in a refrigerator at 8-10°C for 40-50 days after purchase to break their dormancy, which can effectively promote flowering. The Guangzhou Flower Research Center has been introducing narcissus for forced cultivation since 1987, and it is very popular among the public during the Spring Festival flower market every year.
Cold-stored narcissus bulbs should be planted 50 days before the Spring Festival. The cultivation soil should be a fertile sandy loam rich in organic matter, with organic fertilizer pre-buried in the soil or using organic-rich peat soil mixed with a small amount of river sand for planting. Generally, depending on the size of the planting pot, 3-5 bulbs are planted in a clump, and the bulbs must be completely covered with soil. After planting, move the pot to a semi-shaded area with about 50% sunlight, keeping the soil moist. When the leaf buds emerge from the soil, move the pot to an environment with about 70-80% sunlight.
During growth, apply a dilute solution of potassium dihydrogen phosphate every two weeks, and a small amount of nitrogen fertilizer can also be applied. The optimal growth temperature is 15-20°C. Different light intensities, humidity, and temperatures can be used to adjust the flowering period to achieve the goal of blooming exactly during the Spring Festival.
Narcissus is commonly propagated by bulb division, with a natural reproduction rate of 4-5 times. This is usually done in autumn. During propagation, small bulbs on the sides of the mother bulb are detached and planted separately. To accelerate propagation, the mother bulbs should be planted shallow rather than deep. Planting too deep results in fewer offspring bulbs. Additionally, make 3-4 vertical cuts from the stem plate to the top of the bulb, about half the depth of the bulb. After cutting, place the bulbs in clean dry sand to form callus tissue, then transfer them to a 21°C propagation box. When the temperature rises to 30°C and the relative humidity is 85%, many offspring bulbs will be produced in about 3 months, which can be separated and planted. It takes 3-4 years of cultivation for the offspring bulbs to become flowering bulbs.
Narcissus播种繁殖 is carried out in mid-September, using a mixture of decomposed leaf soil, peat soil, and coarse sand for sowing, which is sterilized before use. After sowing, careful management is required, and small plants will emerge the following spring. In early summer, the leaves and roots wither, forming small bulbs. It takes 4-5 years of cultivation for the sown small bulbs to bloom.
The above information provides a detailed introduction to the cultivation and care techniques of narcissus, hoping to bring some flower knowledge to flower enthusiasts.
