How to Transplant Orchids
A comprehensive introduction on how to transplant orchids and the best timing and methods for orchid transplantation, please refer to the detailed introduction below.
Orchids are simple and elegant, with a faint and pleasant fragrance, making them a highly ornamental potted plant. Many people enjoy keeping an orchid as a decoration for their home or courtyard. Although the cultivation method of orchids is relatively simple, to grow them well, it is necessary to repot them regularly. It is best to repot orchids in spring or autumn when the temperature is suitable. When repotting, it is important to choose the right soil and cut away the decayed and dead roots. The following will provide a detailed introduction to the timing and method of repotting orchids.
I. Timing for Repotting
Orchids are generally repotted during the growing season in spring or autumn. The temperature during repotting should be maintained between 10-30 degrees Celsius, preferably on sunny days. The temperature change before and after repotting should not be too great, as it can easily affect the plant's normal growth.
II. Method for Repotting
1. Potting Soil Selection
The new pot should be a larger and deeper ceramic or terracotta pot, and a breathable cover should be placed at the bottom of the pot to ensure good ventilation. Orchids prefer loose and fertile soil. The new soil should be a mixture of half-rotten leaf soil and half-sand. After mixing, the soil should be sun-dried and disinfected before being placed in the pot.
2. Plant Treatment
When repotting, the plant should first be removed from the old pot. Loosen the topsoil first, then gently remove the plant without damaging the roots. Clean and wash the roots to observe and trim them. Cut off the decayed and empty roots and remove the withered and diseased leaves. Then, soak the plant roots in a diluted carbendazim solution for a period of time to disinfect and prevent infection. Finally, place the plant in a shady place to dry.
3. Transplanting Method
When transplanting, hold the pseudobulb with your hand and carefully place it in the potting soil, then fill and compact the soil. Orchids have many roots, so avoid tangling them.
4. Post-Transplant Care
After transplanting, water the plant three times with a 20-minute interval, making sure to thoroughly wet the soil. Then, place the plant in diffused light, and it should recover in about half a month. Do not fertilize before it has fully recovered to avoid root burn. Once new leaf buds emerge, you can apply a light organic fertilizer solution with the watering.
The comprehensive method for orchid transplantation and the best timing and methods introduced above hope to act as a starting point and help solve your problems with green plants.
