Wu Wei
ursus senum severiorum and ex-Bisy Backson
Willow trees and Black LocustWe've experienced that with the other one.
Willows because they look for water sources
Black Locust because they reproduce in 2 ways
1) big seed pod
2) root runners and these runners can get huge, lift up concrete sidewalks, push over stone walls. Just cut one out that was 6 inches in diameter
