I have an issue with my 2nd year blueberry bush. I purchased this "Blue Jay" (I think) variety of blueberry bush two years ago and it has fruited satisfactorily both years. However, it's now sending up much larger-leaved "suckers". Am I looking at a possible grafted variety? Should I cut back the suckers? (They all appear to derive from under the soil). The suckers aren't flowering but I wouldn't expect them to anyways since they came up after the smaller leaved bush finished its fruits. I'm new to Vaccinium culture, would love some advice.
Update: it seems that you were correct. I dug up the bush and found an entangled root system of 2 clearly different species. I didn't think blueberries were grafted but these shoots did have the same aggressive nature as suckers that appear from below ground with other grafted plants. After careful separation, I now have a perfectly happy blueberry bush and what I believe to be some sort of Salix. Thanks everyone!
