You don't have to do anything except not fall in love at first sight.
I'm a plant fanatic, so I understand
I think back to my early days...
Sounds like you're asking how do I keep them apart when I can't keep them apart.. you know the answer to that.
Don't bag a plant .. everything I've ever tried in a bag rotted, even in 30 gallon clear recycling bags with CO2 addition.
Inspect your new plant, and don't bring anything home that's wonky.
