The editor brings you the best time for repotting orchids with some small plant cultivation experience. Detailed content will be shared next.
When is the Best Time to Repot Orchids
The repotting time for orchids can usually be done in spring and autumn. The season is just a supporting reference condition. Temperature is the most critical factor. The optimal temperature for repotting orchids is between 16 to 28 degrees Celsius. Under this temperature range, orchids grow at their peak without experiencing growth停滞 periods due to high or low temperatures. Repotting orchids within this suitable temperature range is conducive to their recovery and growth.
Best Time for Dividing and Repotting Orchids
The repotting time for orchids can usually be done in spring and autumn. The season is just a supporting reference condition, and temperature is generally the most critical.
The optimal temperature for dividing orchids is between 16 to 28 degrees Celsius. Under this temperature range, orchids grow at their peak without experiencing growth停滞 periods due to high or low temperatures.
Within this suitable temperature range, repotting orchids after dividing is beneficial for their recovery and can lead to rapid root establishment.
With temperature as a reference, orchids that bloom in spring are best repotted in late spring, while those that bloom in autumn can be repotted in the following spring.
After blooming, orchids need some time to recover their energy. Once the flowers fade, it's essential to supplement nutrients to allow them to enter a vigorous growth period, which is a good time for dividing and repotting.
Precautions for Dividing and Repotting Orchids
Preparation Before DividingBefore repotting orchids, it's appropriate to supplement some organic fertilizer to stimulate the plant's growth ability. Fertilization can be done about 15 days before repotting.
Watering should be controlled before repotting, generally after the surface of the potting soil is dry, about 5 to 7 days before dividing. This operation allows the growing medium and soil to separate, making it easier to remove the plant from the pot.
Dividing ProcedureStep 1: After removing the orchid from the pot, observe the root condition, trim the circling roots and any overly long roots, remove dead and hollow roots, and properly comb dense roots. Trim the wounds smoothly without any rough edges.
Step 2: When pruning, consider the root distribution after dividing to protect the balance as much as possible. During division, use a sharp utility knife to cut at the connection point near the pseudobulb. Apply healing agent to the wound and let the root wounds dry in a shaded and well-ventilated area for a day.
Step 3: It is not recommended to use carbendazim to soak and disinfect the divided orchids, as the beneficial bacteria on the roots will also be killed. Healthy orchid plants do not need to be disinfected.
Step 4: The mixed orchid growing medium can use the traditional "three old materials" soil, with a small amount of pine needles added. The growing medium should be sterilized before use. Make the growing medium slightly moist before potting.
