D. pinguicula will die if temperatures drop below 7 °C with wet soil. However, it can survive near freezing temperatures if the soil is dry. The plant grows best in warm daytime temperatures from 25 to 35 °C with cooler night temperatures from 10 to 20 °C. [4]
Woody plants survive freezing temperatures by suppressing the formation of ice in living cells or by allowing water to freeze in plant parts that are not affected by ice formation. The common mechanism for woody plants to survive down to –40 °C (–40 °F) is supercooling. Woody plants that survive lower temperatures are dehydrating their ...
Freezing tolerance is rapidly enhanced during the first days of the cold acclimation process when temperature drops. Depending on the plant species, maximum freezing tolerance can be reached after only two weeks of exposure to low temperatures. [ 2 ]
The word succulent comes from the Latin word sucus, meaning "juice" or "sap". [1] Succulents may store water in various structures, such as leaves and stems. The water content of some succulent organs can get up to 90–95%, [2] such as Glottiphyllum semicyllindricum and Mesembryanthemum barkleyii. [3]
The more exposed an area is to the freezing air temperatures, the more quickly it will freeze. In the case of plants in containers this means they are less protected than in ground plants.”
As a succulent plant, Kalanchoe daigremontiana can survive prolonged periods of drought with little or no water. During growth periods with higher temperatures and increased water supply, this species requires proper nutrition, without which leaves show deficiency symptoms such as crippled growth and pustule-like lesions.
Non-acclimatized individuals can survive −5 °C, while an acclimatized individual in the same species can survive −30 °C. Plants that originated in the tropics, like tomato or maize, don't go through cold hardening and are unable to survive freezing temperatures. [3]
Most houseplants are species that have adapted to survive in a temperature range between 15 and 25 °C (59 and 77 °F) year-round, as those adapted for temperate environments require winter temperatures outside of normal indoor conditions. [4]
