The grass turtle's hibernation probably begins after entering autumn. In different regions, due to different climates, the beginning of hibernation is also different. Generally speaking, grass turtles will enter a state of hibernation when the temperature is below 15 degrees Celsius.
In the south, the temperature has always been relatively high, so it usually enters the hibernation period in November at the latest. But in the north, the temperature is generally low, and it may enter the hibernation period in October. After entering the hibernation period, there is no need to change the water for the tortoise, feeding can also be stopped, to avoid food residues polluting the water quality.
Generally speaking, the grass turtle's hibernation period will end from February to April of the second year. Generally speaking, when the temperature rises to 15 degrees Celsius, the tortoise will wake up from hibernation. In the north, because the temperature rises slowly, the time to wake up will be delayed, and the hibernation period will end in April of the next year. In the south, the temperature rises quickly, and the hibernation period can end as early as February. After the end of hibernation, it is necessary to check the eyes and other parts of the tortoise for infection, in order to prevent them from getting sick.
