Reason: Orchids generally do not need much water, so long as the potting soil of the plant is kept slightly moist.If the amount of watering is not well controlled and exceeds the amount that its roots can absorb, the excess water will accumulate in the soil to form water accumulation, and then have an impact on the roots, which will gradually soften the roots.
Measures: It is necessary to take off the pot as soon as possible, cut off some damaged and rotten roots, and then soak them in potassium permanganate solution or carbendazim solution for 20 to 30 minutes for disinfection, and then take them out to dry and re-potted.The amount of water should be controlled in the later period of maintenance, and watering should be carried out according to the state of potting soil.
Reason: In the usual maintenance, if the amount of water irrigated to the orchid is too small to keep up with the amount of water consumed by the plant, resulting in insufficient water supply, then the root of the plant will become soft because of dehydration.
Measures: It is necessary to replenish water in time and gradually increase the amount of watering, so that the plants can slowly absorb water and recover.
Reason: The demand for fertilizer for orchids is not very strong, but the requirements for fertilization are relatively strict, and they do not like thick fertilizer, so the amount of fertilization should be strictly controlled.If there is too much fertilizer, the plant can not absorb it, resulting in excess nutrients, then the residual fertilizer in the pot soil will cause its roots to soften.
Measures: It needs to be watered in time to dilute the excess fertility in the pot soil and let the excess fertilizer flow out from the drainage holes at the bottom of the pot.Then put it in a ventilated place with scattered light, loosen the soil for it, and let the pot soil recover as soon as possible.
