How to deal with the frostbitten leaves of succulents
Softening of the lower leaves is an early sign of frostbite, indicating that the ambient temperature is already low. The pot can be moved to a slightly warmer place to allow it to recover naturally. Most can recover on their own when the ambient temperature slightly increases. Apart from the leaf tips and the outermost leaves being slightly soft and withered, there are generally no other problems. These frostbitten leaves will gradually dry up and fall off with subsequent growth and metabolism.
For succulents that are not cold-resistant, 5°C is a warning line:
Although different varieties of succulents have different tolerance levels for low-temperature environments.
For most succulents, as long as the temperature is above 5°C, growth may slow down or almost stop, and as long as the potting soil is kept dry and the leaves are not sprayed with water, frostbite will generally not occur.
When the ambient temperature consistently drops below 5°C, various degrees of frostbite may appear. In northern regions, it is advisable to move the plants into a warm room for the winter in a timely manner.
In southern regions, it is necessary to stop outdoor cultivation and move the plants to enclosed balconies or window sills for the winter. Apart from avoiding drafts, a small warm pot or short-term use of plant grow lights can be set up to increase light and raise the ambient temperature.
Frostbite in succulents also varies in severity, and should be treated accordingly:
Succulents, with their small and thick leaves, are less tolerant to the cold and are prone to frostbite.
In such cases, many people simply throw away the succulents, which is quite a pity. So, how should frostbitten succulents be treated?
⑴ Soft leaves are an early sign:Saxifraga, being a thin-leafed variety, has poor cold resistance. Softening of the lower leaves is an early sign of frostbite, indicating that the ambient temperature is already low.
The pot can be moved to a slightly warmer place to allow it to recover naturally. Most can recover on their own when the ambient temperature slightly increases.
Except for the leaf tips and the outermost leaves being slightly soft and withered, there are generally no other problems. These frostbitten leaves will gradually dry up and fall off, which basically does not affect the appearance.
⑵ Semi-transparent leaves are moderate:When the leaves of Saxifraga become semi-transparent, it indicates that the water inside the cells has frozen, and this type of frostbite is relatively serious. It can only be moved to naturally freeze in an environment of about 10°C or slightly warmer than the current one.
Never place it near heat sources such as radiators, electric heaters, or grow lights in an attempt to quickly freeze it. Rapid warming can accelerate the leaves' waterlogging and blackening.
This type of frostbite can self-heal in a few days for a small number of cases, but most will leave some black marks due to frostbite or show varying degrees of leaf tip or tender leaf withering.
⑶ Fully transparent leaves are "ultimate":When frostbitten succulents show fully transparent leaves and soft stems, it indicates very severe frostbite. Even if moved to a warmer environment to thaw, the result is usually waterlogging and blackening.
If the roots and stems of such succulents have not yet been frostbitten, you can try to cut the top. If the roots and stems are also transparent from frostbite, there is little that can be done.
