Certified GKH Gardening Expert
If you have planted a bulb, then there may have been a packaging error. Blueberries will not produce a bulb.
I will need quite a bit of information to be able to give you a good solution. What is your USDA climate zone? At what time of year are you attempting to plant? How did you come across the plants?
There are many, many factors that could be the reason for the failure to thrive. As much description as you can offer will help me to give you the best diagnosis possible.
