How to divide orchids to increase the seedling rate (introduction to the precautions for division)

Generally speaking, after two or three years of orchid cultivation, it will fill the pot. At this time, in order to increase the germination rate and the number of varieties bred, and to promote the healthy growth of orchids, you can consider starting to divide the plants. Timely division can also prevent one orchid from becoming sick and infecting other healthy seedlings.

1. Time

Orchid division should be carried out in a relatively warm time, with the temperature preferably between 12-30 degrees. In addition to considering temperature, the best time to divide orchids is generally at the end of their flowering period. Because the growth points of the new buds of the plant have not yet expanded and the flower buds will not grow anymore, the chance of damaging the plant can be minimized when dividing the plant.

2. Remove from the pot

Before removing an orchid that needs to be divided from the pot, you need to stop watering it for a few days to allow the plant's planting material to become dry and loose, making it easier to remove from the pot. When removing the orchid from the pot, be careful not to remove it violently and do not pull the orchid out by grabbing it. You can directly pour out the planting material and remove it from the pot to avoid damaging the orchid seedlings and buds.

3. Root washing

Rinse the orchid seedlings under tap water, and after the substrate is completely washed away, place them in a ventilated and cool place to dry. Appropriate light can also stimulate the dormant buds of the orchid plant and promote later germination.

4. Division

Sort out the root system of the plant, find the division point based on the second or third generation of conjoined plants, and slowly cut them off with sharp scissors. Wait until the plant is completely separated before cutting it a second time. Note that pruning tools need to be sterilized before pruning. After the division is completed, cut off some old roots, rotten roots and diseased leaves, and then spray fungicides such as carbendazim on the wounds to prevent some pathogens from invading the plant through the wounds.

5. Planting

After treating the orchid's wounds, you can plant them in pots separately. Be sure to choose flower pots with drainage holes and loose, breathable planting materials. It is best to sterilize and disinfect them before use. When potting, do not fill it with planting material. You can leave the wound exposed one or two centimeters below to promote wound recovery. Wait a week or two before completely covering with planting material.
