Breeding garters is fairly easy. They need to be taken off feed 2-3 weeks before

hibernation to clean out their digestive tract. Any food left can ferment and kill

the snake. The snakes are then placed in a cool area with the temperature around

50-55 degrees for about 3 months. They need water while in hibernation. They will

be somewhat active during this time. I have seen mine moving about their cages

fairly regularly. After the hibernation period, start warming them up, put them

together and they should breed
