Green Leylandii Hedge

Green Leylandii is the classic choice when the main priority is fast evergreen privacy. Once established and growing well, it can commonly make around 60cm or more of annual growth, allowing a young hedge to develop into a substantial screen much faster than many slower-growing evergreen species.

Its dense foliage also makes Green Leylandii useful for wind protection, larger boundaries and screening unwanted views. The important part is management: start trimming while the hedge is young and keep both its height and width under control. Regular light trimming within healthy green foliage gives a far better long-term result than allowing the hedge to become oversized and then trying to cut it hard back.

The best starting size depends on how quickly you want the hedge to provide visible screening, how long the hedge is and the budget available. Smaller Leylandii plants are easier to handle and are usually the most economical option for long hedge runs. Larger plants give more height and presence from the day they are planted.

Planting density changes as the starting size increases. Use the live plants-per-metre recommendation shown against the exact size you choose rather than applying one spacing rule to every Leylandii plant. The selector above also shows current stock, individual prices and any available bulk-buy options.

Pot-grown Green Leylandii can be planted throughout the year when ground conditions are suitable. Prepare the planting line well, avoid persistently waterlogged soil and make sure newly planted Leylandii receives regular deep watering while the root system establishes. Keeping grass and weeds away from the immediate root area will also reduce competition for moisture.

Begin trimming from an early stage rather than waiting until the hedge reaches its final size. Leylandii responds well to regular clipping while healthy green foliage remains on the branches, but it does not reliably regenerate from old bare brown wood. Establishing the width and height you want from the beginning is therefore much easier than trying to reduce an overgrown hedge later.
