Hey everyone, this year i believe around March i planted a seed of a peach in a pot in my house, and in about a month it came out .. so for about 2-3 months it was in my pot and early summer or mid summer i believe i planted it in the ground... SO it is living right in my backyard and everything is ok... but i know its still small and winter is coming...
the size is only about 3 feet off the ground and its very thin.. but it has many leaves

...
so iam thinking what would i do to make sure it doesnt freeze in winter time?
please help me, iam new to this kind of stuff and will listen to advice and do anything possible to make my tree go through my cold winter here in New Jersey
