normally we pull it out a bit...saw part of the root n cut it off. The remain roots will melt n become the food for other plants. But this apply to mature tank which with micro-organism and bacteria grown. If not, the root melt and will kill all the bacteria. then that area will turn into black color..(died bacteria.) Any plants you planting it there..sure will died coz of root melting.
