Yew hedging, like other evergreens, is best planted in September to October or March to April Buy plants that are 45-60cm (18-2ft) high, as these tend to establish more successfully and grow away better than larger plants. Bare-rooted or root-balled yews are preferable as they are usually cheaper than container-grown stock and seem to establish more readily Once established, a well cared for yew hedge may make up to 30cm (1ft) of growth a year
