As the autumn wind gradually picks up and the temperature gradually cools down, it is a good time to repot orchids and adjust the conservation strategy. Repotting in autumn can not only provide a more spacious and comfortable growth environment for orchids but also effectively prevent the occurrence of problems such as rotten leaves and roots. Next, let's learn in detail how to repot orchids in autumn to ensure the healthy and vigorous growth of orchids.
The importance of repotting in autumn
After a year of growth, the roots of orchids may have filled every corner of the old pot, and even the phenomenon of intertwined roots may occur. Repotting at this time can remove aged and rotten roots, make room for new roots, and promote the roots to absorb nutrients and water better. The nutrients in the old soil have been largely consumed and harmful microorganisms may have accumulated. Changing to fresh, loose and breathable soil during repotting helps improve the soil environment and provide more sufficient nutrient support for orchids. During the repotting process, you can carefully check the leaves and roots of orchids and find and deal with potential pest and disease problems in time to reduce the impact of pests and diseases on the growth of orchids.
Steps for repotting in autumn
Choose a new pot that is slightly larger than the original pot and has good air permeability. Prepare suitable soil according to the orchid variety and growth habit. Generally, it is required to be loose, breathable, and able to retain water and fertilizers. Prepare repotting tools such as a small shovel, scissors, and a watering can.
Remove the pot and clean. Gently tap the pot wall to separate the soil from the pot wall, and then take the orchid out of the old pot. Remove the old soil attached to the roots, check the health status of the roots, and cut off aged and rotten roots. Put the treated orchid in the new pot, fill the new soil to an appropriate height, and gently compact the soil. Water thoroughly to settle the roots and place it in a ventilated and shaded place for about a week to recuperate.
Precautions
Do not let orchids be directly exposed to the strong sunlight at noon to avoid leaf burns. Regularly check the state of orchid leaves and adjust the angle and duration of sun exposure in time. While sunbathing, keep the ventilation of the orchid growth environment good to avoid diseases caused by a hot and humid environment.
Repotting orchids and sunbathing are two important conservation measures in autumn. Through scientific and reasonable repotting operations, we can provide a more suitable growth environment for orchids and promote their healthy and vigorous growth.
