In principle, trees should be cut as little as possible. If it has to be every now and then, there are a few things to keep in mind.
- Pruning should be done in summer, if at all. At this point, the tree is strong enough to close the wound itself.
- Cuts should always be straight and clean. That means the interface should not fray. This is for the simple reason that a smooth interface is not as easy for germs to penetrate as if it were uneven.
- Should one be tempted to cut the tree in the springtime, then one cannot avoid treating the wound. The edges of the wound are coated with a special wound closure agent that is available in specialist shops. The wood core remains free, so the wound can dry faster and the tree can continue to breathe.
- The wound should be checked regularly. After a few weeks, wound tissue must have formed that closes the wound. If this is not the case, the treatment must be repeated.
