The profile indicates that ball maple is the refined breeding form of the Norway maple. This note raises the question of growth. The following data will familiarize you with the proportional relationship between trunk diameter, size growth and crown volume.
How does the maple tree grow?
The growth of a ball maple (Acer platanoides Globosum) depends on the trunk circumference and reaches heights of 350-600 cm and crown diameters of 110-600 cm. The crown starts out spherical and flattens with age.
Interesting data on the growth of ball maple
| Trunk circumference | 18-20 cm | 20-25 cm | 25-30 cm | 40-45 cm | 50-60 cm |
|---|---|---|---|---|---|
| Height | 350-400 cm | 400-450 cm | 450-500 cm | 450-500 cm | 550-600 cm |
| Crown diameter | 110-130 cm | 130-180 cm | 180-250 cm | 250-350 cm | 500-600 cm |
These data apply to an Acer platanoides Globosum that is not subjected to regular topiary. Furthermore, the information should only be viewed as average values under normal conditions. Typical for the growth of the crown is a spherical shape in youth, which gradually flattens with age.
