How to eradicate my pea-like shrub that is taking over my property?
I have an unidentified shrub/bush/tree growing on my property. It has pea-like pink flowers in spring. It has dark green leaves growing in a ash tree pattern, but the stems are brown,prickly and thorny. It grows like a sumac, roots going everywhere and new plants popping up everywhere. They grow to 8 ft tall. How can I eradicate?
From your description, it sounds as though you have a locust shrub. It may be bristly locust (Robinia hispida), or a hybrid between the bristly locust and the black locust (Robinia pseudoacacia). In either case, the way to control a suckering multi-stemmed shrub such as this is either through constant mowing, preventing any sprouts from developing. This could take several seasons to accomplish. Applying a brush killer to the shoots would also work. However, use caution with brush killers. They also can kill desirable plants if the herbicide comes into contact with them. Alternatively, you could dig out the root systems and spray any shoots the pop up afterward with a nonselective herbicide such as the brush killer or glyphosate. In any case, there's no easy solution.
