When to water orchids after potting up in winter

In winter, after potting up orchid plants, whether they are division seedlings or orchid seedlings bought online, the timing of watering should be determined by the air temperature and humidity of the environment where the orchids are kept, and by the moisture level of the growing medium.

According to conventional practice, the time for dividing and transplanting orchids into pots should be in the two periods of early spring and autumn each year. This is because in early spring the leaf buds of the orchid plants have just begun to swell and have not yet emerged from the soil, while in autumn the leaf buds of that year have basically grown and developed into seedlings. Since the temperatures in these two periods are relatively suitable, dividing orchids in these two seasons basically does not affect the normal growth of the orchid plants. After being planted and potted up, they will quickly adapt to the pot or enter the growth phase.

However, when dividing and potting up orchid plants in winter, the first thing to consider is the temperature and humidity of the environment where the orchids are kept. If the temperature of the environment where the orchids are kept is relatively high, around 20°, and the growing medium used for planting the orchids is also relatively moist, then because the indoor temperature is relatively high, the potted orchids can be watered right away. If the temperature is around 10-15° and the growing medium is relatively moist, you can wait three to five days before watering.

If the indoor temperature is relatively low, around 10°, and the growing medium is relatively moist, you can wait one week or ten days before watering again. However, if the growing medium is relatively dry before planting, you must add water to soak the growing medium so it absorbs enough moisture, then take it out and let it drain before planting the orchids. The point is to make sure the growing medium contains a certain amount of moisture, so that after planting the plants there is no need to water for the time being, and watering a while later will not be too late. In addition, no matter which situation applies, the air humidity around the place where the orchids are kept must be a little higher. You can often sprinkle water on the ground around the flower pots to increase the air humidity.

In summary, for orchids transplanted and potted up in winter, the timing of watering should mainly be determined by the temperature of the environment where the orchids are kept, the moisture of the growing medium, and the air humidity of the environment where the orchids are kept. When the temperature is high, because the amount of water evaporating from the flower pot is greater, you can water a bit earlier. Especially in rooms with underfloor heating, you should pay close attention and water appropriately earlier. Also, keep a certain space between the orchid pots and the ground, and at the same time you can place a water tray under the bottom of the pots. In an environment with a relatively low temperature, you can appropriately extend the watering interval. This all depends entirely on the actual situation.
