Dont be parasite

Parasite is a plant that for its survival depends some or all of its energy sources on other plants (called host plants) and causes its host to lack energy (see article symbiosis). In this sense does not include inter-organism competition, nor predation by some insectivorous plants.

While I was exercising around the house, I found parasitic plants. He bit by bit will spoil the plant he is looking for. So do not be a parasite.
