How to raise torch flower culture methods and matters needing attention

The torch flower, whose origin is in Africa, is a flower variety introduced from there in our country, and now it has been widely cultivated and cultivated in our country. The ornamental value of torch flower is very high, so it attracts a lot of people to buy and breed it. However, many people will have some problems if they do not do it properly, so mastering the breeding method is an important step.

How to raise torch flowers

1. Torch flowers like the semi-shady living environment. The torch flower is its growing season in spring and autumn, so it should be properly watered to keep it moist. During the growing period, we should also pay attention to additional fertilization to ensure the nutritional supply of torch flowers during the growing period, so that they can grow larger leaves and flowers.

2, the general family breeding torch flower is put indoors, can keep its growth environment cool, do not put in the outdoor exposure. When the climate is dry, the torch flowers should be watered in time. Usually in the torch flower growth period, we should also pay attention to increase fertilization. If it is some bonsai, we should pay attention to pruning the shape of the torch flower and remove the weeds in some pots to keep the bonsai beautiful.

Culture method of torch flower

1. Soil: torch flower can be cultivated in open field or potted. The planting site should be selected where the terrain is high and dry, leeward and sunny. Before planting, deep ploughing the land and applying some mature organic fertilizer, pot planting requires sandy loam with deep soil layer, fertile soil and good drainage.

2. Sunshine: Catharanthus roseus likes a warm, sunny environment. If potted plants are placed in shade for a long time, the leaves will turn yellow due to lack of light.

3. Temperature: torch flower can be cold-resistant and can be kept at a temperature above 5 ℃ in winter.

4. Watering: if sufficient water supply and fertilization are needed in the growing season, it will grow rapidly. Split the plant in autumn, apply more base fertilizer before planting, supplement the nutrition of the plant, pour water before freezing in the dry areas of winter and spring, and cover the plant with hay or fallen leaves to prevent drying and freezing death.

5. Fertilization: when the flower stem appears, the extra-root topdressing of 2-3 potassium dihydrogen phosphate should be carried out at a concentration of 0.1%, each time at an interval of 7-10 days, or 1% superphosphate of 2% concentration of calcium superphosphate should be used as soil topdressing once, which can increase the stiffness of the flower stem and prevent bending.

6. Pruning: after flowering, the residual flower branches should be cut off as soon as possible so as not to make them bear fruit, so as not to consume nutrients.

Matters needing attention of torch flower

The main results are as follows: 1. In order to make the torch flower grow well and bloom colorful, fully mature organic fertilizer and certain calcium superphosphate or bone powder should be applied before planting.

2. In order to keep the excellent characteristics of torch flower, ramet propagation is better. Ramet propagation should be carried out in autumn, after the persistent root is dug out, the shortened rhizome is found from the root mass of the old root, and then cut with the fibrous root, it can be planted.

Causes of yellowing of leaves of torch flower and its control

1. Caused by lack of light. Lack of light will cause the leaves of the torch to turn yellow. Because the torch flower actually likes the environment with plenty of light, it needs to keep it with sufficient light when breeding, and do not put it in a hidden place for a long time, which will cause its leaves to turn yellow. Therefore, when cultivating torch flowers, we must meet its demand for light, which can be shaded but not excessive.

2. Poor ventilation of basin soil. When raising torch flowers, if the air permeability of the basin soil used is too poor, or the soil is slightly alkaline, it will easily lead to soil consolidation and poor root growth. If the root is not good, the plant is naturally prone to problems, such as yellowing of leaves. So when raising torch flowers, we must choose loose and breathable soil, pay attention to good drainage, and do not use clayey soil.

In fact, the culture method of torch flower is not difficult, we can first understand its growth habits before maintenance. Torch flowers should not be exposed to the sun for too long in summer. They need shade. The amount of watering and fertilization also needs to be paid attention to, and only when these are done well can its growth be ensured.
