The correct method and steps for dividing and repotting orchids

Apply a light fertilizer 5-6 days before dividing the orchids to ensure the potting soil is dry at the time of division; after removing the orchids from their pots, forcefully separate the roots, then prune the roots once more, and afterward soak them for half an hour in a disinfectant solution such as 800-fold carbendazim or thiophanate-methyl; when potting, hold the orchid plant with one hand and fill in soil with the other, firm the soil, and after watering thoroughly, let the plants recover for 3-4 days, then resume normal care.

Preparation before repotting

The quality of the division directly affects the growth of the orchids, so it must never be taken lightly.

Apply a light fertilizer 5-6 days before dividing, which helps replenish nutrients for the plants after division and speeds up their recovery.

Do not water in the 2-3 days before dividing, to ensure the potting soil is dry at the time of division, so as not to damage the orchid roots and flower buds. During the division process, do not pull or tug forcefully; tap the pot wall lightly to make it easier for the soil to come out of the pot.

Disinfection

After removing the orchids from their pots, shake off part of the soil, and use sterilized scissors to cut off withered leaves and dead roots.

Then grasp the roots with your hands and forcefully separate the roots, without damaging the leaves.

After dividing the clumps, prune the roots once more, cutting off the diseased roots and old roots hidden in the middle.

After pruning, soak for half an hour in a disinfectant solution such as 1:800 carbendazim or thiophanate-methyl. Rinse briefly in clean water. Place in a cool, ventilated spot to air-dry for one to two hours, and once the orchid roots are slightly white, apply charcoal ash or sulfur powder to the cut surfaces of the orchids to prevent infection.

Potting

An orchid in a pot is like a person living in a room; comfort and suitability for the orchid are what matter.

First, prepare a pot according to the size and number of the seedlings, and by all means avoid a small seedling in a large pot.

Hold the orchid plant with one hand and fill in soil with the other, firm the soil, one plant per pot. After placing it, gently shake the orchid pot so that the orchid roots and the growing medium have a slight degree of contact.

Care after division

Provide care according to the actual situation; if there is some moisture in the soil, then let the plants recover for three or four days, and then water thoroughly, which is more beneficial for the recovery of the orchid cut surfaces.

For newly planted orchids, there is also no need to spray water; place them in a cool, ventilated environment for 7-10 days, then switch to normal care.
