PlantRoot bound.
A condition in which roots have densely occupied a container and may circle around its shape.
What it means for your plants
Inspect the whole root ball and the plant’s behavior. One root at a drainage hole does not prove severe crowding. A modestly larger pot is often more manageable than a dramatic jump in size.
