The egg laying time of grass turtles is mostly about 30 days after mating. Under normal environment, grass turtles start mating in late April every year, so the egg laying time is mostly from May to August, especially from June to July, which is the peak period of their egg laying. The number of eggs laid by grass turtles is relatively large compared with other turtles. They can lay eggs 3-4 times a year, and each time they can lay 5-8 eggs. After laying eggs, breeders need to hatch eggs. At this time, they can choose natural hatching, that is, relying on natural temperature and humidity to hatch. Although this method is relatively simple, the success rate of hatching is low. In addition, breeders can also incubate artificially, so they need to prepare an incubation tool and ensure a stable incubation environment.

The breeder needs to prepare a soft land and sand pool for grass turtles before laying eggs, because they will dig a pit before laying eggs. When grass turtles lay eggs, breeders need to keep their surroundings quiet and not make too much noise and noise. In addition, although grass turtles lay a large number of eggs in one year, they are not produced at one time, so breeders need to carefully observe their state, and if they find signs of laying eggs, they will immediately transfer to the laying site.
