So I've been doing some research and it looks like many people recommend repotting fly traps yearly. I feel like this is too much work(i have around 100 plants and im a full time student) and waste of medium(peat & sphagnum), so is there any method that will still allow the plants to thrive such as by only changing the top or lower portions of the potting medium? Would it have the same effect when simply unpotting, loosening the mix, then repotting with the same mix? And how can you tell when the medium is not good anymore? Will the repot drastically change vft growth? I have watched the relatively recent video made by FTS relating to this.
