Timing for Repotting Phalaenopsis Orchids
The best time to repot Phalaenopsis orchids is around March in spring and October in autumn, as these periods offer the best temperatures, allowing the plant to adapt quickly after repotting, which is conducive to its growth.
Benefits of Repotting and Changing Soil for Phalaenopsis Orchids
After 1-3 years of care, the roots of potted Phalaenopsis orchids fill the pot, the nutrients in the potting soil are exhausted, and the soil becomes alkaline, compacted, with reduced aeration and water retention, which can no longer meet the plant's growth requirements, so repotting is necessary.
When repotting Phalaenopsis orchids, it is important to maintain a suitable temperature, not exceeding 36 degrees Celsius and not below 10 degrees Celsius, and it is best to choose a sunny day to do so.
Methods for Repotting and Changing Soil for Phalaenopsis Orchids
1. Pot removal: Before repotting, Phalaenopsis orchids should be watered moderately, keeping the potting soil slightly dry for easier removal. When removing the orchid from the pot, avoid using sharp tools. Hold the bulb with one hand, invert the pot with the other, and gently tap to remove the roots. After pot removal, cut off the rotted and old roots, soak in a fungicide solution for half an hour, and then dry before repotting.
2. Prepare soil: Phalaenopsis orchids grow best in peat soil or mostly decomposed leaf soil, as the plant prefers to grow in soil rich in organic matter.
3. Planting: When repotting Phalaenopsis orchids, place some small charcoal at the bottom of the pot, then add 1/4 of the soil, mix in decomposed chicken manure, and plant the orchid.
Key Care Points After Repotting Phalaenopsis Orchids
1. Watering: After repotting, the potting soil should only be kept slightly moist, and the environment should be well-ventilated to make it easier for the plant to adapt.
2. Fertilizing: After repotting, once the plant starts growing new leaves, it can be fertilized with decomposed organic fertilizer or sheep manure.
3. Pruning: Generally, no pruning is needed after repotting, as it has already been done before. However, if there are withered or yellow leaves, they should be removed promptly.
4. Light: For the first half month after repotting, Phalaenopsis orchids should be placed in a bright, well-ventilated area and not exposed to direct sunlight immediately, as the roots may not be firmly established yet, and the leaves can easily wilt.
