A variety of magnificent cacti are completely hardy and perfectly suited to life outdoors. In order for the prickly exotics to survive the winter he althy and happy, they cannot simply be left to their own devices. We have summarized for you here what you should pay attention to when overwintering outdoors.
How can I overwinter cacti outdoors?
To overwinter cacti outdoors, plant them in permeable, well-drained soil, reduce the water and nutrient supply from August onwards and offer them locations protected from the rain, e.g. under a canopy or through a frame with greenhouse film.
Wetness protection from above and below sets the course
In order for cacti to overwinter outdoors, they reduce the amount of water inside. The s alt content in the cell water then increases and the freezing point drops. For this strategy to be successful, hardy cacti must be protected from moisture. By planting the plants in permeable, well-drained soil, an important criterion is met. Also, stop drinking water and nutrients from August onwards.
To protect against excessive moisture caused by snow and rain, frost-resistant outdoor cacti are given a rain-protected location under a canopy. Alternatively, a simple frame made of posts and transparent greenhouse film (€16.00 on Amazon) acts as a rain cover.
