Amazed to know that Butterworth plants also lie in carnivorous category as Venus flytrap and pitchers.
However, it's the soil that makes them having to kill!
So Big soil is one of the reason. What will happen if we provide three primary nutrients Nitrogen, phosphorus and pottasium to the soil. Any indifference in plants behavior. @valth
If we add that to the soil, other plant will likely grow and outcompete the carnivorous plants.
nice answer. I never thought in this way @valth
