The best time is in February
Without its splendid foliage, a spherical acacia gives a clear view of its crown branches. Pruning measures shortly before the start of new shoots achieve an optimal effect, when there is no longer any need to fear severe frosts. By choosing this date, you are also compliant with the Federal Nature Conservation Act, which from the 1st March marks the beginning of the grace period to protect our threatened flock of birds.

Thin out the spherical crown every 3 years
Its spherical crown forms a spherical acacia because the grower's hand is the law of growth Top funding overrides. Instead of concentrating growth on dominant buds, all crown shoots thrive evenly and form a ball. Interventions with scissors and saw are limited to occasional thinning for a light, airy and therefore densely leafed crown. How to do it right:
- Take protective measures against the toxins in the bark
- Dead shoots on Astring saw off
- Shorten broken, weak and annoying branches by up to two thirds
- Scissor blades are set just above an outwardly directed leaf knot
The leaves behind on older spherical acacias Clearance cut sometimes larger cuts with a diameter of more than 2 centimeters. Smooth the exposed wood surface with a knife. Then coat the edges of the wound with a thin layer Tree wax,(€ 18.62 at Amazon *) to the valuable Cambium to protect against late night frosts.
Cut the spherical crown into shape - this is how it works
Wind breakage and lack of space require a shape cut that goes beyond the clearing. Thanks to a high cut tolerance, the spherical acacia cooperates with every cut, as long as the refinement point remains untouched. To cut back the spherical crown:
- Put on gloves to protect against the poisonous bark
- Shorten excessively long crown branches by up to two thirds
- Apply cutting tool a short distance from a leaf knot or sleeping eye
Can't you see a leaf knot as a starting point for the cut? Then first cut the branch in question back to the desired length. In the course of the coming season, a juice jam causes that previously invisible sleeping eyes drive out. If a long stump forms over the shoot, saw off the old wood down to half a centimeter, because it harbors the risk of rot and disease.
Tips
The well-formed crown of a spherical acacia sits enthroned on the trunk of a robust wild species. With the emergence of cheeky trunk shoots, the vigor of the wild rootstock becomes noticeable. Cut off a wild shoot at the base as soon as you discover it below the thickened grafting point. The unloved sprouts Drive type straight out of the root disc, tear off the young wood with a strong jerk.
