When is it better to repot orchids
Regarding the best month for repotting orchids and the precautions for detailed orchid division, the following is a specific introduction to the content of green plant flower planting:
Repotting is necessary for orchids when they have too many seedlings or the pot looks unattractive, or when the growing medium has been used for over two years (repotting without changing the pot is also called turning the pot). However, some orchids die after being repotted. So, what issues should be considered when repotting orchids?
1. First, choose the correct repotting time. It is best to repot orchids in spring and autumn, but not when the season is just changing. During this period, the temperature is not too high or too low, which is conducive to the orchids adapting to the new pot as soon as possible. Winter is also acceptable, but summer should be avoided unless there is a rotting seedling that needs saving. Another timing option is to repot after controlling water for three to five days when the growing medium is slightly dry.
2. Next, prepare the growing medium. Nowadays, orchid growing media tend to be made of hard granular materials. I personally use a mix of bark, brick chips, granular coal slag, and ceramsite, with volcanic stones or planting stones as a topping, and a breathable cover and foam blocks at the bottom. If you find it troublesome, you can also buy some pre-mixed orchid-specific soil on the market. But I enjoy doing it myself; the fun is in the process!
3. Take the orchid out of the pot. Some orchid enthusiasts directly dig out the soil and pull out the orchid with great force, which is incorrect and can easily damage the orchid's roots. The correct method is to wait until the growing medium is relatively dry, then tap the sides of the pot with the palm of your hand to loosen the growing medium. After that, stabilize the base of the plant with one hand and turn the pot over with the other hand to safely remove the orchid.
4. After removing the orchid from the pot, gently shake off the growing medium from the roots and check for any rotting or empty roots. Any rotting or damaged roots must be cut off; don't hesitate to cut them, and cut until the roots look white. Then place the roots in a shady and well-ventilated area to dry, and only repot when the wounds have healed and contracted.
5. The growing medium should be slightly moist but not dripping when repotting. After planting the orchid with such growing medium, there is no need to water it. Place it in a shady and well-ventilated area, and water thoroughly after a week. The old growing medium should be kept at 20-30% if there is no disease and should be placed as close to the orchid's roots as possible. This makes it easier for the roots and old growing medium to adapt.
6. After repotting the orchid, it is like entering a new environment. During this adaptation period, which can last for one to two weeks or even one to two months, the orchid should only be exposed to diffused light and not direct sunlight, and it should be well-ventilated but not windy. The soil should not be too moist, maintaining a slightly damp state. Most importantly, do not fertilize. Some people say that fertilizing is okay after new seedlings appear, but I disagree. Orchids mainly require maintenance and don't need much fertilizer. Isn't the new growing medium you just changed already fertile? Why rush to fertilize?
