Basing soil: Choose soil with strong air permeability; Watering: There is sufficient moisture during the growth period, but no water accumulation. Water once every 20 days in spring and autumn, and once a week in summer; Fertilization: Apply thin fertilizer and liquid fertilizer every month, stop in winter Fertilization; Temperature: It likes a warm and humid environment, but is not resistant to high temperatures. When the temperature is higher than 35°C, it will grow slowly. In winter, it should not be lower than 10°C.

Pot soil requirements

Basing soil requirements

It is very important to plant onions in soil. Clay, powdery, and alkaline soils are not suitable. These soils are not conducive to rooting and drainage. Moreover, the air permeability is poor, and the plants are likely to become stiff and gradually die without any changes.

Watering method

Onion orchids should have sufficient water during the growth period, and keep the pot soil moist, but not waterlogged.

In spring and autumn, water once every 20 days, water thoroughly, and spray appropriately according to the dryness of the environment.

In summer, water once a week. Of course, the watering cycle should be determined according to the local environment. If the weather is dry, water and spray frequently to keep the soil moist.

In winter, reduce watering and keep the soil dry to allow the bulbs to survive the winter safely.

Fertilization method

< /p>

Onion orchids, like other grass flowers, require a lot of nutrients. Except in winter, watering with thin liquid fertilizer once a month can ensure good growth and luxuriant flowering.

Generally, the fertilizing time is when the temperature is relatively moderate during the day and the sunlight is not strong. Keep the leaves and flowers dry at night after fertilizing. The fertilizer can be diluted with appropriate watering the next day.

Temperature requirements

< /p>

Onion orchid likes a warm environment and is not resistant to high temperatures. When the temperature is higher than 35°C, it will grow slowly, especially in summer when the environment is stuffy and improperly ventilated, which can easily induce various diseases and insect pests.

It is relatively strict on temperature in winter. When the temperature is lower than 10℃, it will stop growing, the above-ground parts will slowly wither, and it will slowly re-sprout in the following spring. Therefore, control the temperature well to allow the onion orchid bulbs to survive the winter safely, which is beneficial to the growth in the second year.
