Who doesn’t know an orchid. It’s such a popular houseplant that it’s found in just about every apartment. Its flowers really play with a variety of all colors, so you can choose a color that fits your taste exactly. But to keep it blooming beautifully for a long time, you need to take good care of it, even in winter. Some of the biggest problems with orchids in the cold season include:
- Wet soil
- Cold
- Dry room air
Changes in watering
In winter, an orchid does not need as much water, so water it much less than you are used to. Just once every ten days. Also make sure that excess water does not run off in large quantities onto the flower tray and the plant stands in it for several days. As the orchid is very sensitive to cold, that would be a real bummer! Therefore, the best that can be done is to let the pot stand in lukewarm water for ten minutes. During this time the plant will absorb the necessary water and there is no danger of overwatering. And if after all the plant has taken in more than it really needs, the excess water will then drain off onto a tray where you pour it out.
Caution for colds
If the orchid is standing by a window that is well insulated, then you can safely leave it on the windowsill in winter. However, if it is not insulated or you have any doubts, then wrap the pot in clear plastic sheeting to protect the plant from the cold. Also, place a warm blanket between the plant and the window to prevent the plant from being pulled against it.
Humidity and ventilation
When freezing temperatures hit, people heat like crazy. However, an overly heated room is not good for orchids, as the air is too dry and the plant is more susceptible. So if you have an orchid on a windowsill, place a tray of water on the heater, which will moisten the air. If you need to ventilate the room, protect the orchid from sudden cold air or draughts. You can move it to a warmer room for a while. However, never handle it without reason and do not move it to new locations during the winter. The only exception is if it has been attacked by pests or serious diseases.
Nutrition in winter
Fertilisation is not strictly necessary during this period. If you skip it over the winter, nothing fatal will happen. However, if you do want to give the plant a little boost in the growth of new leaves and roots, you can fertilise lightly. For winter fertilisation, however, you should choose a fertiliser with a significantly reduced nitrogen content in favour of potassium and phosphorus.
