How to help Tillandsia survive the winter
Winter does not provide the ideal conditions for Tillandsia plants, which are accustomed to a warm, humid and bright climate. Here are a few ideas to help them get through the winter more comfortably, looking at each key point.
Light for Tillandsia in winter
Some days are sunny, and even if the sun sets early, you should make the most of it. Tillandsias will thrive near windows, but preferably behind a curtain or blind… especially for species with fewer silvery scales. Ideally, use artificial light so you can choose where to grow them and control the photoperiod.
Humidity for Tillandsia in winter
Heating, whether electric or gas, dries out the air. Firstly, avoid placing Tillandsia near radiators. Secondly, to increase humidity, you can spray water into the room where the plants are kept, or place saucers filled with water nearby to provide a large surface area for evaporation. The plants themselves should be thoroughly moistened at least once a day. Ideally, use a well-ventilated terrarium, where humidity levels are consistently higher and easier to maintain.
Ventilation for tillandsias in winter
The most important thing is that their foliage dries out between waterings; otherwise, they are at risk of rotting. They should therefore not be kept in a confined space where the air is not circulated. In a terrarium, you could install a small fan. And here’s some good news to finish with: the average indoor air temperature suits them perfectly.
Conclusion
Ensuring Tillandsias get through the winter well hinges on a few essential rules: sufficient light, appropriate watering, good ventilation and a stable temperature. By adhering to these conditions, your air plants will remain healthy during the cold season and will spring back to life vigorously when spring returns.
FAQ – How to care for Tillandsia over the winter
How can you ensure Tillandsia get enough light in winter?
In winter, make the most of sunny days by placing your Tillandsia plants near windows, preferably behind a curtain or blind to avoid excessive light, and supplement with artificial light if necessary.
What role does humidity play for Tillandsia in winter?
Indoor heating dries out the air, so it is advisable to increase the humidity by spraying water into the room, placing saucers of water around, or using a well-ventilated terrarium; plants should be thoroughly watered at least once a day.
How can you ensure that Tillandsia plants are well ventilated in winter?
It is essential that the foliage of Tillandsias dries out between waterings to prevent rot, so they must not be kept in a confined space without fresh air.
Can we just leave Tillandsia indoors without taking any special precautions?
The average indoor temperature is suitable for Tillandsia, but to ensure they survive the winter, you need to adjust the light, humidity and ventilation rather than simply leaving them where they are without any care.
Is heating beneficial or harmful to Tillandsia in winter?
Heating dries out the air and can be harmful if it is too close to plants; you should therefore avoid placing Tillandsias directly next to heat sources, whilst increasing the humidity.
