How to trim a young yew hedge

Whether green or golden, yew hedges are perfect for borders, boundaries and decoration, and can easily grow 30cm or more per year. While annual trimming in summer or early autumn is enough to keep your yew hedge tidy and at the required size, formal hedges require more frequent trimming to keep them in perfect shape – two or even three times each summer.

• Hand-held hedge shears

• Safety gloves 

• Protective goggles

• Stable step ladder or platform (if your hedge is on the larger side)

Before trimming, remember to remove any obstacles around the base of your yew hedge and check for birds that may be nesting. If you suspect birds are active, stop work immediately – trimming can be delayed until October if necessary, so you have plenty of time to look after any wildlife.

First, decide the height and shape you’d like your yew hedge to be. Each hedge has a leader – the tip of the main stem, which will determine your hedge's height. If the leader has already reached your desired height, you can go ahead and trim it into shape along with the side shoots.

Traditionally, it is best to cut your hedge so that it tapers at the top. This is known as cutting the hedge to a batter and allows light to reach the base, helping your hedge grow thicker and stronger. However, you can cut your hedge into almost any shape from a young age, particularly for formal topiaries.

When trimming informal yews, simply use your hand-held shears to remove any misplaced shoots and cut the hedge to the size and shape you require. Use secateurs to make more precise cuts, particularly on larger evergreen leaves.

Don’t worry about cutting your hedge back too far – yew is one of the only conifers that will regenerate from old wood.

Yew is highly poisonous – always wear gloves, dispose of clippings safely and wash your hands thoroughly after gardening.
