After selecting the bluegrass, it must be potted properly. Orchids have fleshy roots and require excellent drainage. It's best to use a mix of decomposed leaves or mountain soil rich in humus—commonly known as "orchid mud." This can be purchased at a local flower shop or collected from the mountains. The ideal pH range is 5.5 to 6.5. If you collect the mud from the wild, make sure to sieve out any impurities like stones or debris. For best results, let the mud age for 1–2 years before using it. Before planting, expose it to sunlight for sterilization and then store it in a cool, dry place.
The best time to repot orchids is between March and April in spring or October and November in autumn. Choose pots that are small, deep, or large depending on the size of the plant. Young wild seedlings should be planted in clay pots (deep mud pots) to allow better air circulation and faster drying of the soil, which helps them root more easily. Mature plants, around 2–3 years old, can be moved to zisha or porcelain pots.
When planting, the process differs from regular flowers, especially for famous orchid species. It’s crucial to ensure the roots are fully submerged in clean water. Gently scrub them with an old toothbrush or soft brush, being careful not to damage the delicate roots. Trim off any yellow, broken, or rotting roots, but avoid cutting into the shoots. Once cleaned, let the plants dry in a cool, well-ventilated area until the roots appear white and slightly wrinkled.
Next, prepare the pot by placing coarse stones at the bottom, covering about one-fifth of the pot’s depth. Then add a layer of coarse soil, about 3–5 cm thick. Place the bluegrass into the pot, making sure the roots are spread out and not curled. Always keep the old grass on the outside and position the new growth in the center to allow space for future repotting. Hold the plant in your left hand and the soil in your right, avoiding getting soil on the leaves. Gently lift the plant so the roots can stretch naturally. Add soil while gently shaking the pot to ensure good contact between the roots and the medium. Press the soil around the stem by hand, and shape the surface slightly concave in the middle. Finally, cover the top with moss or pebbles to prevent compaction and reduce evaporation.
Water thoroughly after planting, and place the pot in a shaded area. For the first month, avoid direct sunlight and keep the soil slightly moist, not soggy. After that, choose a location that offers partial shade and morning sun, ensuring good ventilation and airflow.
