Ball Depths & Ball Weight Commercial Plant Production
Minimum Ball Diameter Grading table will indicate minimum ball diameter for each grade. Bigger plants should have a larger diameter ball to capture a larger percentage of the root system.
Ball Depth Ball depth is related to ball diameter. Ball DiameterBall Depth (Height) < 20 inchesDiameter x 75% 20 – 30 inchesDiameter x 66% >30 inchesDiameter x 60%
Ball Depth A 18 inch diameter ball should have a depth of: 18 x.75 = 13.5 inches Round that up to 14 inches.
