How to water orchids during winter vernalization

Vernalization happens in the depths of winter, so watering should strictly follow the rule of "keep dry in winter," keeping the potting soil slightly moist and on the dry side.

During dormancy, orchid plants are in a low-consumption phase, but because the air is dry and there are many strong winds, the potting soil often loses water and dries out. You should check the potting soil regularly and avoid strong winds at the right times. You can water thoroughly once every 10-15 days (it is recommended to use water when the temperature is higher at noon, to avoid stunted buds). Every 3-5 days, spray water once on the surface soil of the pot (the top 1 cm layer) to keep the deeper moisture in the potting soil from evaporating too early or completely, so that the deeper soil remains in a "moist" state, but not wet. That is, it stays in a balanced state with extremely low water content.) In addition, in winter, orchid plants should be misted on the leaves at the right times to replenish water, increase humidity, and remove dust. Leaf misting can be done once every five days. For misting to replenish water, clear water that has settled for several hours is best; for dust removal, a 0.3 percent acetic acid solution is better. In short, in winter it is especially important to maintain the air humidity for orchids!
