Yew Hedge Guide: When to Plant, Spacing and Care

English Yew (Taxus baccata) is one of the most versatile evergreen hedging plants for UK gardens. It can be clipped into a dense, formal boundary, works well in both traditional and contemporary gardens, and is tolerant of a wide range of soil and light conditions. Once established, it is also capable of coping with periods of dry weather.

Planting a Yew hedge successfully starts well before the first plant goes into the ground. Choosing the right planting time, preparing the soil properly and getting the spacing right can all make a difference to how evenly the hedge establishes.

Quick Answer

  • Plant Yew in autumn or spring, avoiding frozen or waterlogged ground.

  • Choose a position with well-drained soil; Yew can tolerate sun, shade and many soil types.

  • Space plants according to their size and planting format rather than using one fixed distance for every hedge.

  • Prepare the planting area by removing weeds and loosening compacted soil before planting.

  • Water newly planted Yew thoroughly and keep the root zone from drying out while the hedge establishes.

  • Allow young plants to establish before concentrating on maintaining the finished hedge shape.

The exact planting density depends on the size and type of Yew you choose, so always check the recommendation supplied for the plants you are purchasing.

When is the Best Time to Plant a Yew Hedge?

The best times to plant English Yew are generally autumn and spring. The RHS recommends planting from late October to mid-December or in March, provided the ground is suitable for planting.

Autumn can be particularly useful because the soil often retains moisture after summer while remaining workable. This gives the plants an opportunity to start developing roots before the following growing season.

Spring is another good option, particularly when the ground has dried out enough to work comfortably. However, newly planted hedges may need closer attention to watering as temperatures rise.

The planting format also matters. Bare-root plants are supplied while dormant and therefore have a more limited planting window, whereas container-grown plants are more flexible.

This distinction is important when planning a new boundary because the suitable planting period can vary between different hedging plants and planting formats.

Avoid planting when the soil is frozen, heavily saturated or difficult to work. Yew is adaptable, but persistently waterlogged conditions can cause root problems.

Where Should You Plant a Yew Hedge?

English Yew is unusually adaptable, making it suitable for many garden situations. It can grow in full sun through to shade and is tolerant of a broad range of soil types as long as the ground drains adequately.

Before deciding where to plant, consider the hedge's eventual height and width as well as the amount of space available at ground level.

A Yew hedge can be useful for:

  • defining a garden boundary

  • creating an evergreen screen

  • separating different areas of a larger garden

  • forming a formal hedge around paths or lawns

  • creating a structured backdrop for other planting

Although Yew tolerates shade well, it is still important to consider the condition of the soil. A shaded site that remains wet for long periods may be less suitable than a drier, well-drained position.

Also consider access for future maintenance. The hedge should have enough room for you to work along it without planting it so close to a wall, fence or pathway that trimming becomes difficult.

What Soil Does Yew Need?

Yew is happy in most well-drained soils and can tolerate chalk, clay and other soil types. Its main requirement is that excess water can drain away rather than remaining around the roots.

If your soil is heavy clay, check how well it drains before planting. Heavy soil itself does not automatically rule out Yew, but persistent waterlogging does.

Where drainage is poor, one option is to create a raised planting ridge so that the roots sit above the most saturated part of the soil. The RHS specifically recommends planting Yew on a ridge in heavy, wet ground where necessary.

Before planting, clear the area of perennial weeds and grass and break up compacted ground. This gives the roots a better environment in which to establish.

There is no need to turn the entire planting area into a heavily fertilised bed. Good drainage, reasonable soil structure and access to moisture are more important starting points.

How Far Apart Should You Plant Yew Hedge Plants?

There is no single spacing measurement that works for every Yew hedge.

The correct distance depends on the size of the plants, their planting format and the density you want the finished hedge to have. Larger plants already provide more physical coverage, while smaller plants need room to develop without leaving excessive gaps.

Everything Plants' English Yew range gives planting densities according to the plant size and format selected, rather than applying one figure across the entire range.

For example, smaller Yew plants may be planted at a higher number per metre than larger specimens. This means you should always use the planting density provided for the specific plants you are buying.

Spacing also needs to reflect the finished hedge rather than simply the size of the plants on planting day. Planting too far apart can leave large gaps for longer, while excessive crowding can increase competition as the hedge matures.

Plant size and hedge design both affect how far apart to plant hedge plants, so the correct spacing for Yew should be based on the plants you're buying rather than one fixed measurement. 

Should You Plant Yew in a Single or Double Row?

A single row is often the most practical option for a narrow boundary and requires fewer plants.

A double staggered row takes up more room but can create a fuller screen. It may be worth considering where there is sufficient planting width and where a particularly substantial hedge is required.

The choice should be made before ordering your plants because the number of specimens you need will change considerably between the two arrangements.

How Many Yew Plants Do You Need?

Start by measuring the full length of the intended hedge.

For a single row, the basic calculation is:

Hedge length × recommended plants per metre = approximate number of plants required

For example, a 12-metre boundary planted at four Yews per metre would require approximately 48 plants.

However, do not use four plants per metre as a universal Yew recommendation. Your chosen plant size and planting format may have a different density. Everything Plants provides different planting recommendations across its Yew range for this reason.

It is worth measuring the planting line carefully before ordering and accounting for gates, openings and any sections where a hedge cannot be planted.

How to Plant a Yew Hedge Step by Step

Once you have selected your planting position and worked out the spacing, the actual planting process is straightforward.

1. Mark the Planting Line

Use a string line to create a straight planting route. This makes it easier to maintain consistent spacing and prevents the hedge gradually drifting away from the boundary.

For an informal garden design, you can use a gentle curve instead, but mark it out clearly before digging.

2. Prepare the Ground

Clear grass and perennial weeds from the planting strip.

Break up compacted soil and check that water can drain away. If the ground remains saturated after rainfall, deal with the drainage issue before planting rather than expecting the new hedge to tolerate permanently wet roots.

3. Mark the Plant Positions

Measure the recommended spacing for your particular Yew plants and mark each position along the planting line.

This is much more accurate than estimating distances as you work and helps create an even hedge.

4. Dig the Planting Holes

Dig a hole wide enough to accommodate the root system without bending or compressing it.

For container-grown plants, loosen the rootball as appropriate before planting. Bare-root plants should have their roots spread naturally rather than being forced into a narrow hole.

5. Check the Planting Depth

Position each plant at an appropriate depth for its root system, avoiding unnecessarily deep planting.

The root system should have good contact with the surrounding soil while the stem remains at a suitable level rather than being buried excessively.

6. Backfill and Firm

Replace the soil around the roots, filling any obvious air pockets as you work.

Firm the soil gently around the plant so it is stable, but avoid compacting the ground excessively.

7. Water Thoroughly

Give each Yew a thorough watering immediately after planting.

Continue monitoring the soil during establishment and water when conditions require it, particularly during dry spells. Newly planted hedges need reliable moisture while their root systems are developing.

Which Type of Yew Hedge Plant Should You Choose?

The size and planting format you choose can influence both the initial appearance of your hedge and how many plants you need.

Bare-root Yew can be a cost-effective option for planting longer lengths of hedge. The RHS recommends choosing relatively small bare-root Yew plants, which are supplied during their dormant period.

Pot-grown Yew provides greater flexibility and is available in different sizes, making it useful when you want to choose the balance between initial cost and visual impact.

Root-ball Yew provides another option where a larger plant is required while retaining the root system within a ball of soil.

Instant Yew hedging is suited to situations where you want a much more established-looking boundary immediately rather than starting with young individual plants.

The choice will depend on the length of the hedge, your budget, planting season and how quickly you want the boundary to look established. Everything Plants currently offers English Yew hedge plants in pot-grown, bare-root, root-ball and instant hedging formats.

How to Care for a Newly Planted Yew Hedge

The first priority after planting is establishment. Good aftercare helps the plants develop their root systems before you focus heavily on shaping the hedge.

Keep the Root Zone Moist

Newly planted Yew should not be allowed to become excessively dry while it establishes.

Check the soil regularly rather than following a fixed watering schedule. Weather, soil type, rainfall and the time of year will all affect how much additional water is required.

At the same time, avoid creating persistently wet conditions. Yew is relatively drought-tolerant once established, but excessive moisture around the roots can be damaging.

Control Competition

Grass and weeds around young Yews compete for moisture and nutrients.

Keep the immediate planting area relatively clear while the hedge establishes. Applying an appropriate mulch can also help retain moisture and suppress weeds, but keep it away from direct contact with the stems.

Be Patient During Establishment

A newly planted hedge will take time to develop into a continuous screen.

Smaller plants are naturally going to take longer to create substantial coverage than larger specimens or instant hedging. This is one reason it is worth deciding how much initial impact you need before choosing the plant size.

The right choice is often a balance between the budget available today and how long you are prepared to wait for the hedge to reach the desired appearance.

When Should You Prune a Yew Hedge?

Yew responds well to clipping and shaping, which is one reason it is so widely used for formal hedging. It can be maintained as a neat, structured boundary rather than being left to grow into its natural tree form.

For a newly planted hedge, however, establishment should come first. Formative pruning can then help encourage the dense structure required for a formal hedge.

Once established, the frequency of trimming will depend on how formal you want the hedge to look and how quickly you want to maintain its shape.

When pruning any hedge, check carefully for active bird nests beforehand. Any active nest should be left undisturbed.

Common Yew Hedge Planting Mistakes

Planting Into Waterlogged Ground

Yew is tolerant of different soils, but persistently wet conditions can cause root problems. Check drainage before planting rather than assuming the plant will cope with saturated ground.

Using One Spacing for Every Yew

Plant size and planting format can change the recommended density. Use the guidance for the specific plants you purchase instead of applying a universal distance.

Planting Without Marking the Positions

Trying to judge spacing by eye can easily result in an uneven hedge. Mark each planting position before digging to keep the line consistent.

Neglecting Watering During Establishment

Even a relatively drought-tolerant plant needs reliable moisture while its roots are becoming established. Monitor the soil, especially during dry weather.

Letting Grass Grow Around Young Plants

Grass can compete strongly with newly planted Yew. Keeping the planting strip clear gives young plants better access to available moisture and nutrients.

Planting Too Close to Obstacles

Consider the hedge's future size before planting directly against a fence, wall or pathway. Leaving appropriate working space can make future maintenance considerably easier.

Is Yew a Good Choice for a UK Hedge?

For many UK gardens, English Yew offers a combination that is difficult to match. It is evergreen, tolerant of sun and shade, adaptable to different soil types and well suited to clipped hedging.

It also works particularly well where a more formal appearance is required. Its dense foliage can be clipped into clean lines, while its ability to tolerate shade makes it useful in positions where some other evergreen hedging plants may be less suitable.

However, Yew does require an important safety consideration. The plant is toxic if eaten, including to pets, and the RHS advises wearing gloves and appropriate protective equipment when handling it.

For this reason, think carefully about where the hedge will be planted if children, pets or grazing animals have access to the garden.

FAQs

When is the best time to plant a Yew hedge?

The RHS recommends planting Yew in autumn, from late October to mid-December, or in spring around March. Avoid planting when the ground is frozen or waterlogged.

How far apart should Yew hedge plants be planted?

The correct spacing depends on the size and format of the plants. Smaller plants can generally be planted at a higher density than larger specimens, so use the recommendation provided for the specific Yew plants you are buying rather than applying one fixed measurement.

Can Yew grow in shade?

Yes. English Yew is highly adaptable and can grow from full sun through to shade. Good drainage remains important regardless of the amount of light the hedge receives.

How often should I water a newly planted Yew hedge?

There is no fixed watering schedule because requirements vary with the soil, weather and time of year. Check the soil regularly and water when necessary to prevent the root zone from becoming excessively dry during establishment.

Is Yew suitable for heavy clay soil?

Yew can grow in clay soil, but the important consideration is drainage. Where heavy soil remains waterlogged, the RHS recommends creating a raised ridge so the roots are kept above persistently saturated ground.

Final Thoughts

Planting a Yew hedge is a long-term garden project, and the decisions made before planting can have a lasting effect on the finished result.

Choosing a suitable planting period, preparing the ground, using the correct spacing and providing reliable moisture during establishment will give your Yew hedge the best foundation.

English Yew's evergreen foliage, tolerance of shade and ability to be clipped into a formal shape make it a particularly versatile option for UK gardens. The most suitable plant size and format will depend on the length of your boundary, your budget and how quickly you want the hedge to create an established appearance.

When selecting plants, you can compare the available English Yew hedge sizes and planting formats to find an option that suits your garden and planting plans.
