Orchids grow slowly, and it takes 3 to 4 years to start dividing roots, and the spring orchid should have 5 to 6 bundles of leaves, while the Huì orchid should have 8 to 9 bundles before dividing roots. The period around Qingming and Qiu Fen is the most suitable time for dividing roots of spring orchids and Huì orchids respectively. When the potting soil is slightly dry, gently turn out the orchid plant from the pot, as wet soil can easily break the roots. Shake off the soil, cut off the withered roots and leaves, and the shrunken pseudobulbs, being careful not to injure the tender buds and fleshy roots. For newly purchased seedlings, cut off the broken roots, and if the broken surface is rotting, cut until the slightly white tissue is visible. Then wash the roots and place them in a shady place until the root color turns white and dry, and then divide the roots. Find a wide distance between two bulbs and cut them apart, applying plant ash or charcoal powder to the cut surface and broken surface to prevent rot. Both parts cut apart should have new buds. Also, cut off excessive old roots to facilitate the development of new roots, and finally repot.
It is better to use a clay pot, while purple sand pots and glazed pots should have good drainage, and magnetic pots are not recommended. The size of the pot should be suitable for the roots to spread out comfortably. The potting soil should be fertile, loose, and well-draining, without alkalinity, with a pH value between 5.5 and 6.5. Mountain soil is a good choice for planting orchids, and if not available, homemade humus soil can also be used.
Orchids are most afraid of waterlogging, so first place a few small stones and charcoal at the bottom of the pot to prevent clogging the drainage holes, then cover with a plastic mesh about 3 to 4 centimeters high. Next, fill in coarse soil, followed by fine soil up to the middle of the pot, forming a convex shape like a steamed bun. Place the orchid in the center of the pot, ensuring the roots are evenly distributed, cover with fine soil, and gently lift the orchid seedling while shaking the pot to make the soil adhere closely to the roots. Then cover with more fine soil, and use your fingers to press the soil from the edge of the pot towards the roots, making the center slightly higher. Finally, add a layer of pebbles, then water from the edge of the pot, place in a shady and well-ventilated area for half a month, and then move to a shaded greenhouse for regular maintenance.
