Container Sizing

Plants sold in nursery pots (also called “containers”) are required to be sold based on the volume of their roots and soil, not just the size of the pot or the plant’s height. This standard helps ensure consistency and accuracy across the industry.

Balled & Burlap (B&B) Sizing

Balled & burlap (B&B) trees are sized in two common ways: caliper or height.

Caliper refers to the diameter of the tree trunk measured 6 inches above the soil line for smaller trees, and 12 inches above the soil line for larger trees. It’s a key indicator of the tree’s maturity and overall strength.

Some trees are also sold by height, which measures from the base of the trunk to the top of the canopy.
