Can Crossvine Damage Or Kill Off Other Plants?

Question

I had a native beauty berry shrub that seemed healthy for several years and a crossvine on a nearby trellis started growing on it and it died

Answer 1

This might happen with aggressive overtaking, but this would have to had covered the plant and surrounded it, preventing it from light and moisture.Typically, with regular pruning, it will not overtake anything.

However, if it was REALLY nearby- it may have choked the roots out with its own.

Here is some more information on the crossvine:
