Orchid Repotting Time and Methods
Tips on the best time for orchid repotting and division, with detailed information as follows:
Friends who grow orchids know that after a certain period, it is necessary to repot the orchids. The purpose is to help the orchids grow better and stronger.
When orchids grow in a pot for a long time, the growing medium in the soil settles, the overall permeability decreases, the development of the root system is affected, and the frequent yellowing of the leaves is closely related to this reason. Moreover, the root system of orchids grows quickly, and once the soil quality decreases, too many roots may rot, leading to various diseases.
Therefore, repotting orchids is an essential operation in the cultivation process. So, when is the best time to repot orchids? What are the good methods? There are indeed some principles to follow.
The best time for repotting orchids: I believe it is in spring and autumn, especially at the spring and autumn equinoxes! Imagine when you take the orchid out of the old pot, it is covered with dense tiny roots, which are the new force for the plant to absorb nutrients. After changing the growing environment, the most significant impact is temperature.
When the temperature is not constant, it is very easy to freeze the roots, affecting the growth rate after repotting. In spring and autumn, the temperature is very stable, perfectly avoiding the situation of large temperature fluctuations. Even after being planted in a new pot, they will quickly enter a state of rapid growth.
The method of repotting orchids also requires a proper sequence and attention to detail, otherwise, it is easy to fail.
1. Cut off the diseased and rotting roots.
After taking the orchid out of the old pot, first wash the soil off the roots with clean water, then use a sterilized pair of scissors to cut off the diseased (black roots) and rotting roots, which can not only reduce the density of the roots but also prevent the spread of diseases. Place them in a properly prepared disinfectant solution to thoroughly disinfect the entire root system and further kill the pathogenic bacteria of root rot disease.

2. Potting.
First, place a breathable cover at the bottom of the pot, then fill in the coarse growing medium. When it reaches one-fourth of the depth, hold the orchid in the pot with your hand, comb the roots well, and let them evenly distribute inside the pot without being too concentrated on one side.
When the coarse growing medium is filled to 5 centimeters away from the pseudobulb, tap the side of the pot to let the coarse medium settle evenly. Then test the stability of the orchid plant and then place a layer of fallen leaves on the top layer to help retain water and moisture.
In addition, during the repotting process, be sure to protect the orchid's roots from breaking, as it is very easy to become infected with pathogenic bacteria otherwise.
After the above steps are completed, water the orchid properly and place the pot in a position with scattered sunlight!
The above is the complete introduction to the orchid repotting time and methods, and the best time for orchid division, for everyone to learn and understand!
