How to cultivate orchid

1. Maintenance methods

1. Temperature: Orchids grow better and bloom more beautifully in a warm environment. Therefore, it can be kept between 20 and 28 degrees under normal circumstances. When it is hot, it needs to be ventilated in time and not left in a stuffy place. In winter, try to keep the temperature above ten degrees.

2. Light: Orchids like light, especially when they are in the flowering period, they cannot grow without sufficient sunlight. You can always place it in a place with sufficient diffuse light, and try to keep the sunlight time no less than six hours a day. But strong direct sunlight must be avoided, and a slightly shaded or semi-shaded place is more suitable.

3. Watering: It likes semi-wet conditions and is afraid of waterlogging. Therefore, watering should be based on the method of "water thoroughly when dry". In other words, wait until the substrate is completely dry before watering, and water thoroughly each time. But water cannot accumulate in any season.

4. Fertilization: It needs to be used once every half a month. The main types of fertilizers used are phosphorus and potassium fertilizers, especially during the flowering period.

2. Breeding techniques

1. Reproduction: Sowing method can be used. This method is suitable when the temperature is between 18 and 20 degrees. If you choose good quality seeds and suitable substrate, germination will be faster. When they grow into seedlings, they can be transplanted. When transplanting, be careful not to damage its roots.

2. Pruning: After flowering, the remaining flower stalks must be cut off immediately. Because if they are not cut off in time, some nutrients will be consumed and nutrients will not be well supplied to the bulbs. The next step is to prune its branches and leaves. Those that are too dense, messy, or dry need to be cut. Its shape can also be repaired regularly.

3. Problem diagnosis and treatment

1. Disease: In summer and autumn, a common disease is "powdery mildew". It will cause varying degrees of damage to both leaves and flowers, which can be treated with chlorothalonil.

2. Pests: "Scale insects" and "aphids" are common pests that we are familiar with. They can be treated with omethoate and other drugs.
