Before planting

- Avoid prolonged drought, which can cause stress and browning.
- Do not cut hard into old brown wood because gaps may remain.
Why choose it

- It naturally keeps a narrow vertical form.
- It tolerates cold winters well.
Good to know
- Dense green growth can conceal dry dead material inside the plant, especially in a continuous dry hedge.
