How to Care for Phalaenopsis Orchids in Summer
Let's talk about how to care for Phalaenopsis orchids in summer and some small gardening knowledge about their daily care techniques. Please see the detailed introduction below.
Phalaenopsis orchids are native to subtropical rainforest areas and are epiphytic orchids. They are famous for their butterfly-like appearance and are loved by many people. Phalaenopsis orchids prefer to grow in warm environments and are afraid of the cold. In winter, they can easily die when the temperature drops below 5 degrees Celsius, so they should be placed in a warmer environment. 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 the following six aspects: temperature, fertilizing, repotting, lighting, water and fertilizer, and pest and disease control.
1. Temperature
Phalaenopsis orchids enjoy sunlight and dislike shade. Therefore, caring for them in summer is easier than in other seasons. It is sufficient to keep them in an environment of 12-15 degrees Celsius, and in summer, they can be exposed to full sunlight. Phalaenopsis orchids can tolerate high temperatures of up to 28 degrees Celsius, but avoid direct sunlight in the intense summer sun to prevent leaf burn, with a shading level of 50%. On cloudy and rainy days, supplemental lighting is needed to make the flowering period start earlier.
2. Fertilizing
Because Phalaenopsis orchids have a long flowering 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, it is important to rinse the pot and plant with clean water after fertilizing 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 damage the roots. If the temperature remains stable above 20 degrees Celsius, it will be more beneficial for the growth of Phalaenopsis orchids after repotting. If it is below 20 degrees Celsius, it is not recommended to repot.
4. Lighting
The sunlight in summer is quite strong, so it's best to take timely shading measures for the plants. Do not place them where they can be directly exposed to the sun. Instead, put them in a place with diffused or slanted light, and during extremely hot weather, keep them in a shady place. However, because summer is the flowering season for Phalaenopsis orchids, they should not be kept away from sunlight for too long.
5. Water and Fertilizer
Phalaenopsis orchids require more water and fertilizer 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, you can spray water around the plant to increase air humidity. For fertilizing, apply liquid fertilizer once every 7 to 10 days, preferably organic fertilizer, with the concentration not too high. The best time for fertilizing is in the afternoon, combined with watering. After watering, fertilize 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 ventilate regularly and ensure a clean growing environment for the plants, as well as to spray disinfectants and insecticides periodically. If pests or diseases are found, take immediate action to prevent further harm.
