Blueberry root bound
Quick answer
If your Blueberry is root bound, the most likely cause is: Blueberries have fibrous root systems that easily become root-bound in smooth plastic pots. Roots circle the perimeter, forming a dense mat that prevents water absorption and stunts growth.
Start here:
- 1. Unpot the plant and aggressively score the root ball with a knife, cutting vertical slits to sever circling roots.
- 2. Tease the roots outward before repotting into a significantly larger container (at least 24 inches deep and wide).

Keep this Blueberry from ending up root bound again
