How to Care for Phalaenopsis Orchids in High Summer Temperatures
Comprehensive guide on how to care for Phalaenopsis orchids in high summer temperatures and the cultivation methods and precautions related to flower care. Let's learn about it together.
Phalaenopsis orchids are native to subtropical rainforest regions and are epiphytic orchids. They are famous for their butterfly-like appearance and are loved by many. Phalaenopsis orchids prefer to grow in warm environments and are averse to cold. In winter, temperatures below 5 degrees Celsius can easily lead to death, so they should be placed in a warmer environment to grow. It is also necessary to fertilize regularly to ensure nutrient supply. Moreover, repotting should be done in spring and autumn. Let's understand how Phalaenopsis orchids are cared for in summer from six aspects: temperature, fertilizing, repotting, lighting, nutrient and water management, and pest and disease control.
1. Temperature
Phalaenopsis orchids prefer sunlight and dislike shade. Therefore, caring for them in summer is easier than in other seasons. Normally, keeping them in an environment of 12-15 degrees Celsius is fine. In summer, they can be exposed to full sunlight, and they can tolerate high temperatures of 28 degrees Celsius. However, avoid direct sunlight in the summer heat as it can burn the leaves; 50% shading is sufficient. On cloudy and rainy days, additional lighting is needed to make the flowering period shorter.
2. Fertilizing
Since Phalaenopsis orchids have a long blooming period and can tolerate high temperatures, it is necessary to fertilize regularly, especially in the hot summer when the evaporation of water and nutrients accelerates. Fertilizing usually occurs after watering. However, after fertilizing, it is important to rinse the pot and plant with clean water to prevent the inorganic salt components in the fertilizer from burning the roots and leaves.
3. Repotting
The best time for repotting Phalaenopsis orchids is at the end of spring and the beginning of summer, when they are preparing to grow new roots. Repotting during this period will not harm the root system. If the temperature is stable above 20 degrees Celsius, it will be more conducive to the growth of the orchids after repotting. It is not recommended to repot them if the temperature is below 20 degrees Celsius.
4. Lighting
The sun's rays are quite strong in summer, so it is best to take shading measures for the plants promptly and not place them in direct sunlight. Instead, they should be placed in a location with diffused or slanting light, and in extremely hot weather, in a shady place. However, since summer is the flowering season for Phalaenopsis orchids, they should not be kept away from sunlight for too long.
5. Nutrient and Water Management
Phalaenopsis orchids require a lot of water and nutrients in summer. The watering frequency is about once every 1-2 days, and the amount of water should be twice as much as in spring. Additionally,喷洒 water around the plant to increase air humidity. In terms of fertilizing, apply liquid fertilizer once every 7 to 10 days, preferably organic fertilizer, and do not make the fertilizer too concentrated. The best time to fertilize is in the afternoon, which can be combined with watering. After watering, apply the fertilizer and then water again to rinse.
6. Pest and Disease Control
Pest and disease control for Phalaenopsis orchids mainly focuses on prevention. It is important to ensure good ventilation and a clean growing environment and to regularly spray fungicides and insecticides. If pests or diseases are found, timely measures should be taken to prevent further damage.
