Seedling: stop watering ahead of time, so that the pot soil becomes dry and easy to take off the pot.The mother plant is then carefully removed, shaking off the matrix from the roots.If the substrate is hardened or sticky, it can also be washed away with mild water flow.
Root washing: Wash the roots with tap water to avoid soaking the roots, which is easy to infect diseases and insect pests.After washing the substrate, the plant is placed in a ventilated place with a certain scattering light to dry.
Plant division: After the plant is dry again and the root of the orchid becomes soft, cut the second or third generation of the conjoined body as a unit with sterilized sharp scissors at the bulb with a large gap.
Disinfection: After all the plants are divided, some old roots, rotten roots and withered leaves are cut off, and some fungicides such as charcoal powder or carbendazim are smeared on the wound to disinfect and sterilize the roots.
Potting: After the wound is disinfected, you can start potting.When dividing pots, you can decide how many plants to plant according to the size of the pot you choose, generally three to five plants are more suitable for one pot.When potting, hold the flower seedling in one hand, put it in the middle of the pot, let the roots distribute evenly, and then put the prepared culture soil into the pot.You can add soil while gently shaking the pot, which can make the soil and roots close together.
Management: After potting, you can pour it once, and then put it in a cool place with good ventilation to keep the humidity suitable.Wait until the new shoots have sprouted before watering them again.
After the division of orchids, wounds are usually left, and if not treated, it is easy to invade the bacteria and make the plants sick.You can apply some charcoal powder or sulfur powder on the wound of the root to prevent the invasion and infection of pathogens.Carbendazim or thiophanate bactericide can also be sprayed on the wound of the orchid strain to disinfect it.
