Evergreen hedging plant that will make either a formal or informal hedge as required. If creating a tall hedge, then three or four rows should be planted @ roughly 12" centres to provide stability for a very heavy hedge. Clipping should be done two or three times a year to keep the base dense and the hedge, as it grows, should be tapered in slightly so that it gets narrower at the top than it is at the bottom.
For a normal 4-6ft hedge, one single row should be sufficient. Planting distance 6-9" apart in the row. Box likes good drainage, and should you need to feed the box (if it pales in colour) then use a granulated fertiliser such as Growmore, or similar. Do not water via an automated watering system. They dislike wet and will defoliate if they do not dry out quickly. Water the soil at the base of the plant during dry spells.
