How to grow orchids? Why don't orchids bloom?

1. How to grow orchids

Temperature: To grow orchids, you need to provide them with an environment with suitable temperature, ensuring that the temperature is between 20 and 25 degrees. It grows better in a warm environment. Therefore, when it is too cold or too hot, you need to take warming and cooling measures in advance.

Light: Orchids need sufficient light to grow well, but they are afraid of strong light and cannot tolerate direct sunlight. Therefore, it can be maintained in an environment with more scattered light or semi-sunlight. It still needs to be shaded when the midday sun is too strong in summer.

Water: Orchids do not like moisture and do not have a strong demand for water. If there is too much water in the potting soil, it will hinder the breathing of the roots, and if water accumulates, it will cause root rot. Therefore, you must control the amount of water when watering, and keep the soil 80% moist. You don't need to water in winter to avoid frostbite.

Soil: Orchids do not like moisture, so the soil for growing them needs to be well-drained and loose, which is not easy to form water accumulation. And it needs to be rich in humus to provide certain nutrients for the plants. Moreover, the pH value of the soil should be between 5 and 5.6, preferably slightly acidic.

Temperature discomfort: Orchids need sufficient temperature difference between day and night to bloom. The daytime temperature should be between 18 and 21 degrees, and the nighttime temperature should be between 7 and 10 degrees, ensuring that the temperature difference between day and night is about 10 degrees. This will allow it to bloom faster.

Insufficient light: Orchids need a certain amount of sunlight to grow. If it is deprived of light for a long time, it will not be able to produce flower buds. It needs to be placed in a sunny place where it can receive scattered light.

Improper watering: If you water too much, it will cause excessive growth. You need to drain the water in time to promote the germination of flower buds. If you water too little and there is insufficient moisture, it will be difficult for the plant to bloom and you will need to replenish water in time.

Improper fertilization: Excessive fertilization will lead to excess nutrients, which will cause the orchid branches to grow vigorously and inhibit the differentiation of flower buds.

Seedling stage: It is difficult for orchids to bloom in the seedling stage. Only mature orchids can bloom beautiful flowers.

Influence of pests and diseases: If the plant is affected by pests and diseases such as leaf spot and whitefly, it may not bloom. To prevent and control the disease in a timely manner, you can spray a solution of thiophanate-methyl.
