When orchids change pots, the diseased roots, empty roots and rotten roots should be cut off. After pruning, spray disinfectant on the wound to avoid infection and decay.

Move the orchids to a cool environment for maintenance, so that the plants can adapt to the new soil. After 2 weeks, it is necessary to provide sufficient light to promote the full photosynthesis of plants. The spring equinox, autumn equinox and about 20 days after the flowers wither are all suitable seasons to fertilize orchids. The best fertilization time is at night, and the next morning, 1 times water is poured. Every 2-3 weeks 1 time.

During flowering and budding, there is less water. In the rainy season, you should move back indoors or build a shed to shelter from the rain. There should not be too much water in the early morning or evening in summer, and the amount of water can be increased appropriately in autumn. In dry season, spray every evening. Orchids under the curtain should be rotated 1 time every half month, so that the orchids can receive light on all sides, which is beneficial to the balanced growth of plants. When it is cool in autumn, potted orchids should be moved out of the shade and allowed to bask in the sun for half a day in the morning, but attention should be paid in autumn.
