I recently came across two no name blueberries and repotted them. They've got some new growth and are looking better than when I got them. I've noticed a new sprout coming up and was wondering if this should be culled. I know very little about blueberries and was hoping someone could help. I know there's a wealth of people with experience with blueberries on this site! Aren't most blueberries grafted onto certain rootstocks? If so, this wouldn't be worth keeping or trying to root as another plant, right? It's hard to tell in the pic, but the little sprout/growth is coming out from under the soil line.
