Answer:
Hi Tracey, I really need to see a photo to make a diagnosis of your problem. The issue of suckers is a worry – usually robinias only sucker when they are very sick or when the top has been pruned off, or the roots have been cut. About all that I can suggest is that you wait and see what happens. Don
