Trimming the Taxus baccata hedgerow (common name yew, or European yew) we mostly do this only once a year.
In general this hedgerow does not perform well. We expect two reasons for that, one being the water household is not okay and secondly, on the other side, there are too many plants too close to it.
The total length is 28 meter (92 feet). The West half (toward the waterfront and shown on the photo’s) of this hedge performs much better than the East part (toward the street). To trim the West side I use a hedge shears. The East half is so open that I can not use a hedge shears and hence for that I use a hand pruner.
To get to the top the ladder is needed.
