Flower turtles don't grow fast. After they are born, they can only grow 1-2 cm a year. Compared with other turtles, the growth rate is relatively slow. Under different growth environments, their growth rates are also different. If they live in a comfortable environment and have plenty of food, they will grow faster. If the breeding environment is harsh and the food and nutrition are abundant, they will grow faster, but they can only grow 3-4 cm a year at most.

The length of the Chinese turtle in adulthood will be about 20-30 cm, the length of the carapace can reach about 20-25 cm, the width is mostly between 18-20 cm, and the height is also 10 cm. Turtles of different genders have different sizes in adulthood. If they are raised in the same environment, the size of male turtles will be smaller, about 20-25 cm. Female turtles will be larger, and their body length will be about 30 cm in adulthood.

If breeders want them to be bigger, they should give them enough space so that they can move freely. They should also be given enough food to ensure adequate nutrition in the process of their growth and development. They should also be given a suitable living environment, so that their bodies can grow bigger.
