Webb of Ivy

The root of the ivy grabs hard at the soil, 

Leaves creep up the tree in a tangled embroil, winding like a Webb grabbing as it goes, how high it grips, nobody knows

Hard to pull off the bark, some cancers appear the same destroying fresh tissue removing it is insane, doesn't matter how you take it away there's always such destruction to the outer membrane.

Killing the light, stopping the growth, unimaginable damage to the unwary host 

Leaving the tree like a dead wooded ghost
