Krinum

A bulbous plant like crinum (Crinum) belongs to the Amaryllidaceae family. In nature, it can be found in subtropical and tropical areas. And he prefers to grow such a flower on the sea coast, on river and lake shores, as well as in those places that are periodically flooded. Several species can be found in the arid Cape Province of South Africa.

From the Latin language "crinis" is translated as "hair". The name of such a plant is associated with the appearance of the foliage. Very long, xiphoid or linear, hanging down, it really looks like hair. Having a long neck, large bulbs reach 60 to 90 centimeters in length and about 25 centimeters in diameter. The leaves are also very long and grow up to 150 centimeters. Young leaves do not have a flat shape, like most other types of amaryllis, but they are rolled into a tube. This is their hallmark. The peduncle bears an umbrella-shaped inflorescence on which large pink or white flowers flaunt. The fruit is a capsule containing large and fleshy seeds. In their shells there is a supply of liquid, which is enough for germination and the appearance of a new flower bulb, while water from the outside is not required.

Such a plant has found its use in decorating cool rooms, halls, cinemas, terraces, lobbies, and concert halls. It can also be grown in a spacious apartment, and it will also grow well in a cold winter garden. There are also species that are grown in aquariums.

Crinum care at home

Illumination

Needs bright lighting, no shading. Growth is faster under more intense lighting. At the end of the winter period, the flower is gradually accustomed to bright lighting, as burns may appear. It is recommended to place it on a south-facing window, while the leaves should not touch the window glass, as this can cause burns.

In summer, if possible, take the plant outside, while protecting the place from heavy rains. If grown in a room in the summer, frequent ventilation will be required. In autumn and winter, good lighting and regular ventilation are needed.With poor lighting, the leaves below them wither rapidly, but the young ones still grow. Can be grown in artificial light, with 16 hours of daylight.

Temperature regime

Such plants are divided into 2 groups:

• South African, native to the arid Cape (South Africa)... Grown in cold greenhouses. In summer, you can keep in the fresh air, while in subtropical areas they can stay outside for the winter, but light shelter will be required. In spring and summer, temperatures between 22 and 27 degrees are needed. In winter, they feel normal at 2-6 degrees.
• Originally from tropical areas. Grown in a warm greenhouse. In the summer, you can move to the street, but the place must be protected from gusts of wind. In spring and summer, it needs a temperature of 22-27 degrees. In winter, there is a dormant period. At this time, you need a coolness of 16 to 18 degrees (at least 14 degrees).

Humidity

Any humidity is suitable. For hygienic purposes, you need to regularly wipe the leaves with a damp sponge.

How to water

During active growth, watering is abundant and warm water is used. Watering is necessary as soon as the topsoil dries up. When flowering is over, you need to water less, but the soil should always be moderately moist. In winter, during the dormant period, watering should be rare, and the flower itself should be rearranged in a cool room. Do not allow the soil to dry out, as the bulbs have a rather fleshy root system, which performs its function regardless of the season.

If you want flowering to occur in winter, the dormant period must be postponed to the end of the summer and the beginning of the fall, while reducing watering. When the flower arrow begins to grow, you need to resume normal watering. To stimulate flowering, do not water the flower for 7-14 days.

Top dressing

Top dressing is carried out 2 times a month. To do this, use a liquid fertilizer for flowering indoor plants, while the dosage is used as recommended on the package. They begin to feed when young foliage appears, and stop when all the flowers wither.

Dormant period

A dormant period begins after the end of flowering. During this period, old foliage gradually withers, and new ones replace it. Krinum needs deep rest, but if it does not exist, then flowering will not come next year. In springtime, re-flowering sometimes occurs, while it is quite simple to achieve it in the Crinum Moore species.

Earth mix

To prepare the soil mixture, combine leaf and clay-sod soil, peat, humus, and sand in a ratio of 1: 2: 1: 1: 1. It is recommended to add a small amount of charcoal to the mixture.

Transplant features

The transplant is carried out before the beginning of the period of intensive growth. Adult specimens are transplanted once every 2–4 years. When planting, the bulb should rise by a third above the soil surface. You need to plant in large and deep containers, since this plant has a powerful root system. Gently remove old soil along with damaged roots. At the bottom, make a good drainage layer of expanded clay.

Reproduction methods

You can propagate it by bulbs or seeds.

You should not rush to separate the young bulbs, because thanks to them, the flowering will be more abundant. Separated babies bloom after 2–4 years (depending on their size). For planting, use a container with a diameter of 9 to 12 centimeters. After 12 months, it must be transplanted into larger pots, and after the same amount of time - in containers with a diameter of 15 to 17 centimeters. During growth, young specimens need more frequent feeding and watering. In large containers (19-24-28 centimeters), such a plant is from 3 to 4 years old, while it has a lot of baby bulbs, and abundant flowering is observed for 3-4 years.

Pests and diseases

It can settle in the leaf sinuses mealybug... Also, damage to the krinum can cause spider mite... When overflowing during the rest period, root rot appears.
