How cacti survive outdoor winters
This article introduces how cacti survive outdoor winters and provides detailed insights into the care of cacti during the winter season, as follows:
Mentioning cacti often brings to mind their easy maintenance and longevity, but this perception is incorrect. I used to have no interest in cacti, as they are covered with spines and are not particularly beautiful. However, in recent years, they have become popular plants, complementing various styles perfectly. Now, it is hard to imagine home care without their presence. They look great in cement pots or red clay pots, so today I want to share with you how to care for cacti in winter.
Cacti thrive in well-lit environments with a growth temperature around 20 degrees Celsius. The temperature during winter should not drop below 5 degrees. For cacti recently purchased from the flower market or those that have been acquired for a short time, it's best to move them indoors. If the cacti have been acclimated for a long period, they can remain outdoors.
Cacti moved indoors should be placed in a well-lit and well-ventilated area. Sufficient light not only promotes photosynthesis but also helps raise the temperature, providing warmth, especially during winter. Full sunlight is best for safe wintering. Larger cacti do not need to be shaded during summer, while smaller cacti need some shade.
Cacti are plants that grow in desert areas and are highly drought-resistant. They require minimal watering, and during winter, it's best not to water them at all to avoid root rot and death.
How cacti survive outdoor winters
In winter, there is no need to fertilize cacti. Since they grow relatively slowly, we don't expect them to grow tall or fast. Therefore, no fertilizer should be given during their dormant period in winter. After about two years of care, it's good to repot them during the spring and autumn seasons. Fresh soil will provide sufficient nutrients, and adding some base fertilizer will meet their growth needs.
The soil for repotting does not have special requirements; it just needs to be permeable and breathable. Well-draining sandy soil or sandy loam can be used, as long as the particle content is higher.
