Opinions are divided about the usefulness of cutting cucumber.
The fact is, that cut plants bring harvestable fruit earlier and also have a better overall yield. The cutting methods are quite different.
Has proven itself u.a. following method: Once the plants 4 to 5 have formed normal leaves, you sharpen them 2 or 3 leaves. The resulting side shoots 1. trim one cuts across that 4. leaf. You can leave it at that. Who doesn't shy away from the effort, cuts the side shoots 2. Order after the fourth or fifth leaf. In the case of hybrid varieties, pruning can be omitted.
