In winter, conditions change, even at home: your green plants need more attention.
The days get shorter, the sun is less visible: in winter the brightness drops, and what can have an impact on our morale also has an impact on houseplants!
Those which are the most sensitive to it are flowering plants and plants with colored or variegated foliage.
If their leaves start to yellow, it is because of the lack of light.
Which plants to choose for a cold environment?
A cold veranda is actually an unheated veranda. Unheated but not exposed to the climate! During the hibernation period, from November to February, no plant survives the frost. Excessive draughts and humidity never go well with the olive tree or the aster. Once these precautions are taken, many species accept temperatures of 10°C.
In spring, the veranda can even be an ideal transit for your young fruit trees before their stay on the terrace. And as soon as May, from 15°C, it becomes possible to grow your first tomato plants.
