Not true. VFTs prefer nutrient poor soil. In fact, the main reason owners of these plants fail to keep them alive is not watering them with pure enough water. You’re supposed to use water with a TDS below 100ppm. Rain water or RO water preferred.
The reason these plants can survive in such low nutrient soils is because they evolved a different mechanism for obtaining nutrients.
I was wondering about that, I saw a botanist’s video about a carnivorous plant nursery and he mentioned plants like VFTs and pitcher plants evolved in high-precipitation areas where the soil has been leached of nutrients.
I’ve seen both conditions with pitcher plants, don’t know what to think.
The swamp down the street is packed with nutrients, has to be, and that’s where I’ve seen them thrive. OTOH, I’ve seen fields of them where it’s marshy, but I’d guess the soil is thin like everywhere else around here.
What country/region is this? If you don’t mind me asking
I water all my indoor plants with rainwater, makes a stunning difference.
Even better is aquarium water!
Obviously not if they can’t handle the nutrients, like Venus fly traps
