How do I kill suckers and runners from my neighbours Robinia Mop Top Tree

I have to date poisoned approx 200 suckers as they appear. They are like mini trees which disappear after poisoning with tree killer only for more to appear in different spots.

Hi Brian,

Applying Yates Zero Super Concentrate to cut robinia suckers is the only way to control them. Dilute the product as directed and paint the cut surface within a minute of cutting. eventually the old root system will starve and start to rot away.
