How to grow large orchids and precautions

Growth habits of large orchids

Large orchids prefer a semi-shaded growing environment and are afraid of direct sunlight. The most suitable growth temperature is 18-30 degrees Celsius. If the temperature is below 5 degrees Celsius or above 35 degrees Celsius, it will grow slowly. During the reproductive growth period, it is best to control the temperature at 5-18 degrees Celsius. It likes a humid growing environment and needs to be replenished with water in time. It should be planted in fertile soil rich in humus.

Light requirements for large orchids

Large orchids are suitable for planting in places with strong scattered light but not direct sunlight. However, some varieties prefer more sunlight and can be placed in places where they receive short periods of direct sunlight. The light intensity is lower in winter, so they can be exposed to the sun appropriately. In other seasons, they can be shaded and receive scattered light.

Orchid growth temperature

The suitable growth temperature for large orchids is between 15-25 degrees. When the temperature is lower than 5 degrees or higher than 30 degrees, its growth will stagnate and then slowly enter a dormant period. In addition, when the orchid is reproducing, it is best to provide a growth environment of 15 degrees, which is conducive to its seedling cultivation.

How to grow large orchids

Large orchids are suitable for planting in loose, fertile, humus-rich, slightly acidic soil. Water them moderately at ordinary times, and do not allow water to accumulate. Just keep the soil slightly moist. If it is dry in summer, spray water in time. In winter, water them after the potting soil is dry. In addition, apply thin fertilizer once every half a month.

Watering large orchids

The maintenance seasons of large orchids are different, and the climate and other conditions are different, so the watering intervals are also different. In spring and autumn, it is too difficult to water once every 2-3 days. In winter when the temperature is relatively low, water once a week. During the flowering period and the leaf bud growth period, water less often.

Fertilizing large orchids

When planting large orchids, you can apply some base fertilizer. During the growth period, mainly apply fertilizers containing nitrogen, phosphorus and potassium. Pay attention to applying thin fertilizers frequently and do not use concentrated fertilizers. Generally, it is sufficient to apply it once a month.

Large orchid pruning

The main objects of pruning for large orchids are withered and yellow leaves, old, weak and diseased roots, and stems left after the flowers have withered. They all need to be cut off in time to avoid these "problem" flowers, leaves and roots competing for and consuming a large amount of nutrients, which can easily result in the inability to provide the plant with sufficient nutrients needed for growth in time, thereby weakening the overall growth of the plant.

Precautions for caring for large orchids

Large orchids need to be maintained in a suitable place. In spring and autumn, they can be moved to a sunny place outdoors. In summer, they can be placed in semi-shade for maintenance by providing shade. Also, pay attention to keep water away when it rains a lot. If the temperature is low in winter, move them indoors. After flowering, pick the flowers in time and keep 1-2 flower buds.
