If it is based on whether they can reproduce, the artificially bred grass turtles will grow up in about 5 years. Because they can reproduce after about 5 years of growth, they already belong to adult turtles physiologically.
But if they are adult by size, it takes 8-9 years for them to grow up. Because the body length of grass turtle needs to reach 20 cm before it can be regarded as an adult turtle, it takes longer.
If breeders want grass turtles to grow faster, they should raise them carefully. For example, feeding them more nutritious foods, ensuring their living space and giving them more sunshine can promote their growth and development.
2. How big can grass turtles growThe average body length of grass turtles is about 20 cm, but their body length is different with different genders and different growing environments. For grass turtles raised in the same environment, the female turtles will be relatively large in size, and their body length will be more than 20 cm in adulthood. Some of them have good physique, and their body length can grow to about 28 cm and their weight can reach 3 kg. Male turtles are relatively small in size. Most of them are about 15 cm long in adulthood, the maximum is no more than 20 cm, and their weight is about 1 kg.
