There is no need to feed a carnivorous plant. They will catch their own. More food doesn't = more or larger leaves per se. Is your plant outside? If not, MOVE IT outside.

It is outside(and I know it will catch enough food because of it) but I'm looking to make sure it doesn't have an idle trap at ant time. I'm not looking for larger leaves, but more leaves and a bigger plant as a whole. Since feeding is basically fertilizing, will constant feeding cause much difference?
