Before planting
- Allow space for a crown about 5–7 m wide. A spherical habit does not make this a miniature tree for very narrow passages.
- Check the trunk and graft height. Total tree height also includes the crown, which continues to grow.
- Choose sun or partial shade with well-drained soil that retains moderate moisture.
Why choose it
- Its regular crown creates an orderly feature without constant clipping into a ball.
- The leaves give seasonal interest and may turn yellow in autumn.
Care
- Water young trees during establishment and prolonged drought.
- Routine hard shaping is unnecessary. Remove damaged branches and shoots growing below the graft union.
Good to know
- Older crowns become broader and flatter and may no longer form a perfect sphere.
- Acer platanoides is invasive in parts of North America. Check local restrictions before planting outside its native range.
