For thousands of years in China, there have been the four gentlemen of plum, orchid, bamboo, and chrysanthemum, who have been loved by generations due to their simple and elegant qualities. As one of them, orchids have been cultivated in our country for more than two thousand years. The phrase "Autumn orchids are fresh, green leaves with purple stems, the whole room is filled with beautiful people" is a fine word praised by ancients. You must want to keep a pot of orchids at home, so how do you care for orchids? Next, I will discuss orchid cultivation methods.
Orchid Cultivation Methods
1. Soil Selection
To care for orchids well, good soil is essential. Generally, the soil should be dominated by humus, using decomposed leaf soil or mountain humus. In southern regions, decomposed leaf soil, vermiculite, and perlite are used to artificially compound a loose, ventilated, and permeable growing medium.
2. Fertilization
When orchids grow vigorously, fertilization is necessary. It is divided into two parts: one is applying base fertilizer in the growing medium, and the other is top-dressing during the growing period. In the orchid growing season, apply dilute cake fertilizer water (about 15%) every two to three weeks, or 0.1% urea fertilizer water mixed with 0.2% potassium dihydrogen phosphate fertilizer water. Orchids should be changed every year, and uncomposted fertilizer should not be applied to avoid root rot.
3. Watering
In spring and autumn, water every two to three days. In the hot summer, water once or twice a day. In winter, with low temperatures, orchids are in a dormant state, so water once a week. When watering, prevent water droplets from splashing on the leaves to avoid black spots. In summer, it is necessary to sprinkle water around it from time to time to increase humidity. Rainwater or snowwater is the best for watering, and if tap water is used, it is best to let it sit for a few days.
4. Temperature
For orchids grown in northern China, they should be moved indoors when the temperature drops to 5°C around the time of Frost's Descent. Initially, after moving indoors, windows should be opened frequently to maintain air circulation. Keeping the room temperature at about 10°C in winter is ideal. After Guyu, move it outdoors for maintenance. The suitable temperature for orchid growth is 16-24°C. In winter, the indoor temperature should be between 10-12°C during the day and 5-10°C at night, and the summer temperature should not exceed 30°C.
5. Lighting
Orchids enjoy shade and are afraid of direct sunlight. Therefore, shading is appropriate in spring, summer, and autumn. Usually, shading is done from 9 am to 6 pm, and the curtains are opened in the morning and after 6 pm to allow scattered sunlight. In winter, it can be moved to a place with diffused light indoors to avoid direct sunlight.
6. Pruning
During the growing period, orchids need to be pruned, such as removing old yellow leaves, which is beneficial for leaf growth. It is especially important to prune leaves with diseases to prevent infection. The pruning shears should also be disinfected to prevent infection.
7. Repotting
Orchids should be repotted once every 1-2 years after flowering. When potting, first place 3 centimeters of tile pieces or cinders at the bottom of the pot for drainage. Then, add a layer of growing medium and place the orchid seedling in the center of the pot, straighten the roots, and let them naturally unfold. Gently lift the orchid seedling halfway while shaking the pot to make the soil adhere closely to the roots. Fill the soil to 2-3 centimeters away from the pot opening and gently press it down.
