"Halo" doesn't apply to the entire object, only to its lower section

So I added an Halo component to my tree object, and as you can see with the attached screenshot, it only appears to apply the Halo on the tree’s lower section. How can I amend it and get it to be for the entire tree?

The tree has a capsule collider that reaches its top, for the record.

It might be at the bottom because its origin is at the bottom. You could move it up, but the terrain system would probably make the trees be in the ground.

Make an empty gameobject the child of the tree, give that the halo and move it wherever you want the halo to be.
