Hello and welcome to FlytrapCare!
i live in chicago and the winters can get nasty like below zero what would you reccomend doing?
An unheated room in a house, a heated garage that stays fairly cool, and an unheated south facing porch are all good options. You basically have to decide on what to do with your plants based on what you have available to you. If you have no other options, the fridge method can be used as well. Just leave the plants outside until the chance of freeze comes and then put them in their chosen place for dormancy.
if i buy a venus fly trap online it says over night shipping an adult venus fly trap but how do I know if the soil the plant comes in is healthy for the flytrap?
I'd imagine that most places that sell flytraps know what kind of soil to pot them in. But if you are uncertain, you can ask them or simply repot when you get it.
