Starting seedlings: Stop watering in advance and let the pot soil become dry to facilitate removal from the pot. Then carefully remove the mother plant and shake off the substrate from the roots. If the substrate is relatively hard or sticky, it can also be washed away with gentle water flow.

Root washing: Rinse the roots with tap water. Avoid washing the roots by soaking, as this can easily infect the roots with insect pests. After washing the substrate, place the plants in a ventilated place with a certain amount of scattered light to dry.

Dividing: After the plants have returned to dryness and the orchid roots have softened, use sterilized, sharp scissors to cut open the bulbs with relatively large gaps in units of second or third generations.

Disinfection: After all the plants are divided, some old roots, Cut off rotten roots and blighted leaves, and apply some charcoal powder or carbendazim and other fungicides on the wounds to disinfect and sterilize the roots.

Potting: After the wound is disinfected, potting can be started. When dividing pots, you can decide how many plants to plant according to the size of the flower pot you choose. Generally, it is more appropriate to divide three to five plants into one pot. When potting, hold the flower seedling with one hand and place it in the middle of the pot so that the roots are evenly distributed, and then put the prepared culture soil into the pot. You can gently shake the pot while adding soil to make the soil and roots closely fit together.

Management: After potting, you can water it once and then place it in a cool place with good ventilation to keep the humidity appropriate. Wait until the new shoots sprout before watering again.
