Goldfish hanging orchid basin change is best in spring, after March is mainly after flowering or after autumn cool, these two periods of basin change is ideal
Remove the Ipomoea lobata from the basin. The root system of the plant grows too long in the basin. The root system mainly grows in the area where the soil contacts the flowerpot. The old root should be cut off with scissors or knives. The original soil ball should be removed one third of the periphery, and the whole soil should not be removed, otherwise the root system would be difficult to recover. Then put the drain under the flowerpot on the insect screen. If it's a breeding seedling, you can change it into a bigger basin.
After the insect control net is padded, a centimeter of soil is paved, and a bit of mature organic fertilizer or slow-release compound fertilizer is added, and then a centimeter of soil is covered. Place the original soil ball with the outer root removed in the center of the flowerpot, and start filling. When the soil is filled to half the height of the flowerpot, lift the original flowerpot soil ball upward to make it three to four fingers lower than the flowerpot. Then fill the soil evenly, adjust the flower ball, make it just in the center of the flowerpot, compact the newly filled soil, pour water, and place it in a cool and ventilated place for two to three days.
