When stressed by drought, the spherical maple leaves become limp
As more typical Heart root if a spherical maple spreads its roots predominantly just below the soil surface. Only in loose, sandy-loamy soil do the strands reach a depth of 80 cm and more.

- Water the globe maple regularly with normal tap water for the first 5 years
- Thoroughly water older trees during summer drought
- Two to three times a week Water hose Let it run for 30 minutes

mildew there. Both fungal infections spoil the shapely leaves on the spherical maple. How to act correctly:- Tar stains: remove all maple leaves from the garden in autumn to break the pathogen's development cycle
- mildew: cut off all infected leaves and burn them
- Then spray the crown with a mix of water and fresh milk in a ratio of 9: 1

Burn the foliage or otherwise get it out of the garden so that the fungal spores don't spread from wind or rain again the next year.
Tips

The planting depth within the nursery should be maintained as precisely as possible in the garden. Otherwise, the roots will suffer from a lack of oxygen and stop supplying the crown.
