Tree Sizes and Weights

The following tables represent the recommended root ball sizes for trees that are grown in the ground in a nursery and harvested by being balled and burlapped (B&B). Root ball size is based on height or caliper size of the trees. These root ball sizes can vary according to growing conditions surrounding a tree. For example, a plant might require a larger root ball than required due to a wide spreading root system because of natural habit, infrequent root pruning or out of season transplanting. There also might be circumstances when a smaller root ball is recommended as with container stock, or plants that have been frequently root pruned or transplanted. The following tables will help in determining estimated sizes and weights for trees.

Standard root ball sizes for Upright Evergreens

2’ – 3’ 12”
3’ – 4’ 14”
4’ – 5’ 16”

Helpful Hints

Tree and Shrub Measurement Standards

    • To determine the height of field and container grown plant material, measure from ground level (or soil level) at or near the top of the trunk flare to the top of the plant.

 

    • To determine average height for coniferous evergreens measure from the top of the root ball (or trunk flare) to the midpoint between the upper-most whorl and the tip of the leader.

 

    • Caliper measurement of a tree trunk should be taken six inches above the ground, up to and including four-inch caliper size. If the caliper at six inches above the ground exceeds four inches, the caliper should be measured at 12 inches above the ground.
