Best Plants for Privacy Along Fences and Boundaries

Why Planting Is Better Than Fences for Privacy

Fences have their place, but they have limitations. A 2 metre fence is the legal maximum without planning permission in most areas, and even that may not block overlooking from upstairs windows. Fences also blow down in storms, rot after 15 to 20 years, and look stark. Plants, on the other hand, can grow taller than 2 metres (in the case of trees), filter wind rather than block it (which reduces storm damage), and provide habitat for wildlife.

In Chiltern villages like Princes Risborough, Wendover and Great Missenden, gardens on the hillside are often overlooked from properties above. A 2 metre fence will not solve this. A hedge of beech or yew at 2.5 metres, or a row of pleached trees at 3 metres, will. The planning rules allow hedges and trees over 2 metres as long as they are not a "high hedge" causing unreasonable loss of light to a neighbouring property.

Best Climbers for Fence Privacy

Climbers are the quickest way to add privacy to a fence. They use the fence as a support and grow up to cover it within a few seasons. Plant climbers 30 to 60cm from the fence, train them in with wires or trellis.

• Star jasmine, evergreen, scented, sun or shade, slow to establish then vigorous
• Clematis, fast-growing, wide range of colours, prune by group
• Honeysuckle, native, wildlife-friendly, scented, tolerates shade
• Wisteria, dramatic flowers in spring, needs strong support
• Climbing roses, thorny, good for security, long flowering season
• Ivy, evergreen, but can damage fences and walls

Best Hedges for Boundary Privacy

Hedges are the best long-term solution for boundary privacy. They are more expensive than climbers initially but provide better privacy and last for decades.

• Beech, holds brown leaves through winter on chalky Chiltern soil
• Yew, dense, evergreen, long-lived, formal
• Laurel, large leaves, fast-growing, evergreen
• Leylandii, fast but needs regular cutting, can cause neighbour disputes
• Privet, semi-evergreen, fast-growing, tolerates chalk
• Hornbeam, similar to beech, better on clay soils

See our hedging plants guide for detailed recommendations by soil type.

Best Plants for Quick Privacy

If you need privacy quickly, choose fast-growing plants. Be prepared to maintain them properly, as fast growers can get out of hand.

• Bamboo (clumping varieties only, avoid running bamboo), 3 to 4 metres in 2 years
• Leylandii, 1 metre per year, but needs cutting twice a year
• Laurel, 30 to 60cm per year, evergreen
• Privet, 30 to 60cm per year, semi-evergreen
• Pleached trees, instant screening at 3 to 4 metres, expensive but effective

A warning about bamboo: running bamboo (Phyllostachys) spreads aggressively and can damage paving and foundations. Always choose clumping bamboo (Fargesia) and never plant running bamboo in the ground.

Best Plants for Privacy in Shade

Many boundary spots are shaded by neighbouring buildings or trees. These plants will give privacy in shade:

• Ivy, evergreen, tolerates deep shade
• Honeysuckle, tolerates shade, scented
• Yew, tolerates deep shade, evergreen
• Laurel, tolerates shade, large leaves
• Hornbeam, tolerates shade, holds brown leaves in winter
• Photinia, tolerates light shade, evergreen

Pleached Trees for Above-Fence Privacy

When you need privacy above the 2 metre fence line, pleached trees are the answer. These are trees trained on a clear stem (usually 1.5 to 2 metres) with a flat panel of branches on top. They give privacy at 2.5 to 3.5 metres without blocking light lower down.

Common choices for pleached trees in the Chilterns:

• Hornbeam (best for clay soils)
• Beech (best for chalk soils)
• Lime (Tilia)
• Photinia (evergreen, red new growth)
• Holly (evergreen, slow-growing)

Pleached trees cost 200 to 500 pounds each (mature specimens). A row of 5 trees for a 10 metre boundary costs 1,000 to 2,500 pounds planted. They are not cheap, but they are the most effective solution for overlooking from above.

Tips for Privacy Planting

1. Check boundary ownership before planting on a boundary. The fence may belong to your neighbour.
2. Choose the right height, over 2 metres may need planning permission if it is a fence or wall. Hedges and trees can be taller.
3. Plant at the right distance, 30 to 60cm from the fence for climbers, 60 to 90cm for hedges.
4. Support climbers with trellis or wire attached to the fence.
5. Water regularly for the first season, new plants need weekly watering from April to September.
6. Discuss with neighbours, a tall hedge can cause disputes. Talk first, plant second.
7. Consider pleached trees for above-fence privacy.

Common Mistakes

• Planting running bamboo. It spreads into neighbouring gardens and can cause serious disputes. Always choose clumping bamboo.
• Planting leylandii too close to the boundary. It will grow wide as well as tall, and neighbours can complain. Plant at least 1 metre from the boundary.
• Not supporting climbers. Climbers need wires or trellis. Without support they fall off the fence.
• Planting too close to the fence. Plant 30 to 60cm from the fence to allow for growth and maintenance.
• Not watering in the first year. New plants need regular watering. A dead hedge is an expensive mistake.

Frequently Asked Questions

How high can a privacy hedge be?

There is no height limit for hedges in most areas. However, under the High Hedges Act 2003, a neighbour can complain to the council about a hedge over 2 metres that is blocking light to their property. The council can order you to reduce the height. Discuss with neighbours before planting a tall hedge.

What is the fastest-growing plant for privacy?

Leylandii is the fastest, growing up to 1 metre per year. But it needs cutting twice a year and can cause disputes. Laurel and privet are slightly slower (30 to 60cm per year) but easier to manage.

Can I grow a privacy hedge in shade?

Yes. Yew, hornbeam and laurel all tolerate shade. See our hedging guide for more.
