Crinum - Crinum.
Content:
Crinum is a bulbous, member of the Amaryllidaceae family. It grows wild in the subtropics and tropics. This culture grows on the sea coasts, along the banks of rivers and lakes, and also in areas of periodic flooding. Several varieties are found in the Cape of South Africa with periods of drought.
Translated from Latin, "crinis" means "hair". Crinum is named so because of the shape of the leaves. Elongated, in the form of a sword or lines, hanging down - all signs of hair. The bulbs are large, have an elongated neck, their length is 0.6-0.9 cm, and their diameter is about 25 cm.The leaves are also very elongated, reaching a length of up to 1.5 m. Young foliage is not flattened compared to the foliage of other varieties of this family, it rolled into a tube. This sets the species apart from the rest. On the peduncle there is an umbrella-shaped inflorescence, it bears large flowers of pink or white color. The fruit is a capsule containing large and dense grains. Their shells have reserves of water, it will be enough for germination and the emergence of a new flower bulb, and no liquid from external sources is needed.
This culture is used to decorate rooms, halls, cinemas, terraces, lobbies, and concert halls. Krinum can be grown indoors and in a winter garden with cold climates. There are varieties cultivated in the aquarium.
Agrotechnical techniques for indoor growing krinum.
Illumination level.
The plant needs bright light, no shadow is needed. If the lighting is more intense, then the crinum will grow faster and more actively. At the end of winter, the culture gradually learns to bright light in order to avoid the appearance of burns. It is advisable to place the flower pot on the southern windowsill, and there should be no contact of foliage with the glass of the window, because the leaves can burn.
In the summer, if possible, you need to take the flower out into the street, the place should be protected from heavy rain. If you grow a plant in the summer in indoor conditions, then the room must be often ventilated. In the autumn and winter seasons, it is required to light well and regularly ventilate the room. In poor light conditions, the lower leaves wither very quickly, but the growth of young foliage still continues. Can be grown under artificial light sources with 16 hours of daylight hours.
Temperature conditions.
Vegetation falls into two categories.
South African, homeland - Cape province, South Africa (arid climatic conditions). Vegetation is cultivated in a greenhouse with a cold microclimate. In the summer season, the plants are kept outdoors, and in the subtropics, you can leave flowers outdoors for the winter season, but you will need to easily cover them. In the spring and summer seasons, temperature conditions are required in the range of 22-27 degrees. In the winter season, the bush grows well at a temperature of 2-6 degrees.
Homeland - the tropics. Plants are grown in greenhouses with a warm microclimate. In the summer season, flowers are transferred to outdoor conditions, and the place must be protected from strong winds. In the spring and summer seasons, the krinum needs a temperature regime in the range of 22-27 degrees. In winter, the plant is dormant. During this time period, a cool temperature of 16-18 degrees (at least 14 degrees) is required.
Moisture level.
The humidity level can be anything. For hygiene reasons, regular wiping of the leaves with a damp cloth or sponge is necessary.
Watering.
When the plant is actively growing, you need to water it with large volumes of warm water. Watering is carried out when the surface soil layer dries up.When the crop finishes blooming, watering is reduced, but the soil must be constantly moderately moist. In the winter season, at the dormant stage, they rarely watered, the krinum is rearranged in the cool. The soil should not be allowed to dry out, because the bulbs have a sufficiently dense and voluminous root system that does its job, despite the season of the year.
If you want the crinum to bloom in winter, the dormant stage is transferred to the last summer days or to the first autumn, watering in this case is reduced. When the flower arrow begins to grow, you need to water it again as usual. To stimulate flowering, do not water the bush for one to two weeks.
Fertilization.
Vegetation is fed twice every 30 days. For this purpose, a liquid top dressing is used for flowering indoor vegetation, and the dose recommended on the pack or sachet of fertilizer is used. Top dressing begins when young leaves appear, and ends when all flowers wither.
Rest stage.
The dormant stage begins after flowering ends. At this stage, there is a gradual withering of old leaves, they are replaced by new ones. The flower needs deep rest, otherwise it will not bloom next year. In spring, the plant begins to bloom again.
Soil mix.
To prepare a soil mixture, you need to combine leaf and clay-sod soil, peat, humus and sand in a ratio of 1: 2: 1: 1: 1. Also, a little charcoal is poured into the substrate.
Transfer.
Crinum is transplanted before it begins to grow rapidly. Mature plants are transplanted every two to four years. When planting, the bulbs should rise 1/3 above the surface soil layer. Planting is required in large and deep containers, because the root system of this vegetation is powerful and strong. The old soil should be carefully removed along with the damaged roots. At the bottom of the tank, it is necessary to build a good drainage system using expanded clay.
Reproduction.
Reproduction can be done using bulbs or by seed.
Take your time to separate the young bulbs, as they decide how the plant will bloom - abundantly or poorly. The separated baby will begin to bloom in two to four years (depending on its size). The bush is planted in a container with a diameter of 9-12 cm.A year later, the plant is transplanted into a larger container, and a year later - into a container with a diameter of 15-17 cm.When young seedlings grow, they need to be fed and watered more often. In large containers (sizes - 19-24-28 cm), the culture grows for 3-4 years, a large number of baby bulbs appear, it begins to bloom profusely in three to four years.
Harmful insects and diseases.
In the axils of the leaves, the appearance of a mealybug may occur. A spider mite is also harmful to the plant. If the krinum is overflowed with water during the dormant stage, then it can be affected by root rot.
