Unfortunately, I don't have much that I can share with you on that front.

But it reminds me of searching for protocols when doing a science experiment - everyone says something different. What I learned is to look at multiple sites and then take the "average" of all of them. Tends to work pretty well

Hi! I feel strangely well-placed to respond here - my horticulturalist wife used to tend a garden of carnivorous plants professionally.

I asked her advice and she said,

"Avoid blogger sites. Some are good, but most have no clue and just regurgitate what they read on some other blog. If you want the super in-depth info, use Google scholar and search for the plant name plus whatever you need to know. Soil ph, propagation technique, etc. For more approachable info though, search normally for ' university extension'. University extension work is when a university is doing public outreach stuff - publishing information in easy to read and apply ways. "

So... Searching for "Venus flytrap university extension", I found this page which gives a very straightforward breakdown on how to care for your own personal Audrey-jr.
