The Culture method of Ling Jian Hua

Soil: fertile, loose, good drainage neutral or slightly acidic sandy loam should be used. Light: like warm sunlight, not direct sunlight, winter moved to indoor sunlight. Humidity: Keep humidity in the air in spring and summer. Temperature: The temperature should not be lower than 10℃. Frame: thin bamboo pole as a pillar, the stems and leaves will be distributed on the frame. Fertilization: apply decomposed thin cake fertilizer water once every 15-20 days. Diseases and pests: stem rot, brown spot and root knot nematode, etc.

1. Selection of soil

Arrow flowers like to grow in a humid environment, so it is suitable to choose fertile, loose, good drainage neutral, or slightly acidic sandy loam culture.

II. Sufficient light

1. The flower likes to grow in warm sunlight, but it should not be exposed to strong light. It can generally be maintained outdoors in sunny places. In winter, it should be moved to indoor sunny places for maintenance. In summer, it can be maintained in ventilated and semi-shady places. During this period, direct sunlight should be avoided.

2, should not rain, otherwise there will be yellow stems, or even withered phenomenon, if placed in a cool place for a long time, will affect the differentiation of flower buds, if not ventilated environment growth, will easily occur pests.

III. Maintaining humidity

In spring and summer, water can be sprayed regularly to the plants, and water can also be sprayed around the flowerpots, which is conducive to improving the humidity in the air and promoting the growth and flowering of the plants.

IV. Suitable temperature

The flower is not resistant to cold. In the middle and late October in the north, it can be maintained in a place with sufficient sunshine. From November to March of the following year, the temperature should be kept at 10-15℃, from March to June at 13-18℃, from June to November at 20-25℃, and in summer, ventilation, cooling and shading should be carried out appropriately.

V. Setting up support

Because the stems and leaves of the flowers are relatively soft, it is necessary to use thin bamboo poles as pillars, which can generally be tied into oval brackets, and then distribute the stems and leaves neatly and evenly on the brackets, and then bind them with ropes, so as to avoid breaking, and it is conducive to ventilation and light transmission, so as to promote the symmetrical and beautiful shape of the plants.

VI. Rational fertilization

During the growth season of the flower, the decomposed thin cake fertilizer can be applied once every 15-20 days, and after the Spring Festival, the liquid fertilizer should be applied once every 10 days. During this period, the overgrown lateral buds and the buds sprouting from the base should be cut off in time, which is conducive to reducing nutrient consumption and maintaining beautiful plant shape. In the bud stage, the quick-acting phosphorus fertilizer can be applied 1-2 times, which is conducive to promoting the flower to be large and colorful.

VII. Prevention and control of diseases and insect pests

Stem rot, brown spot and root knot nematode are easy to occur in flowers of Lingjian. Stem rot and brown spot generally occur. 50% carbendazim wettable powder can be sprayed with 1000 times solution. Root knot nematode can be irrigated with 80% dibromochloropropane emulsifiable solution with 1000 times solution. Aphids, scale insects and red spiders are easy to occur if ventilation is poor. 50% fenitrothion emulsifiable solution can be sprayed with 1000 times solution.

VIII. Change the basin at the right time

1. The flower needs to be replaced once every 2 years or so. Generally, it can be replaced in spring and autumn. Organic sandy soil can be used as pot soil. When replacing pots, part of the old soil and dead roots should be removed, and then new culture soil should be supplemented. Generally, 4 parts of rotten leaf soil, 3 parts of garden soil, compost soil and 1 part of sand should be mixed and prepared, and appropriate amount of bone powder should be added as base fertilizer.

2. The potted flowers can be grown under scattered sunlight. In summer, shade should be carried out to prevent the leaves from being damaged due to excessive light intensity. In rainy days, they should be moved indoors for maintenance. After autumn, they can fully see the light. Otherwise, insufficient light will lead to difficulty in flowering.
