Privacy Hedge: Best Plants for Geneva Gardens

For a privacy hedge in Geneva, the most reliable plants are yew, hornbeam, privet, osmanthus, photinia and elaeagnus, or a mixed informal hedge combining several shrubs. The right choice depends on the height you want, how exposed the site is to the bise, the space available and how much clipping you are prepared to do. Avoid cherry laurel and thuja, for reasons this guide explains.

What you expect from a privacy hedge

Before choosing a plant, be clear about what the hedge needs to do. A hedge is not judged on density alone: it must also last, without demanding more work than you planned for.

• Opacity: do you want a screen all year round, or only in summer?
• Final height: a 2 m hedge is not a 4 m hedge, either for maintenance or for neighbourhood rules.
• Available width: some plants need room to spread.
• Exposure: full sun, partial shade, prevailing wind.
• Maintenance you can accept: a precisely clipped hedge needs more visits than an informal one.

The most reliable evergreens

Evergreens keep their foliage in winter and provide a continuous screen. These are the ones that perform well in our climate.

Hornbeam deserves a special mention: although it is deciduous, it holds on to its dry leaves through the winter. It therefore forms a decent screen all year, with a more natural look than a conifer hedge.

The informal, countryside-style hedge: a solid alternative

An informal hedge mixes several shrubs (for example dogwood, hazel, viburnum, spindle and dog rose), some evergreen, others deciduous. It is not clipped to a line: you let it take a natural shape and thin it out as needed.

Its advantages are clear:

1. Biodiversity: flowers, berries and shelter benefit insects and birds.
2. Resilience: if one plant suffers in a dry summer or from disease, the others compensate. A single-species hedge can be affected as a whole.
3. Lighter maintenance: one trim a year is generally enough.
4. Appearance: flowers and autumn colours change with the seasons.

Its drawback: it is wider and less opaque in winter than an evergreen hedge. It suits large plots and boundaries that look onto open countryside.

Plants to avoid

Cherry laurel (laurelle) is among the invasive exotic plants whose sale has been banned in Switzerland since 1 September 2024. It remains very common in existing gardens, but it should no longer be planted: it is better to choose something else for a new hedge, and to consider replacing it gradually if you already have one.

Thuja forms a dense screen, but it is very thirsty and suffers in dry summers: brown patches, dieback, sometimes the loss of entire plants. It does not regrow from old wood, which makes the damage hard to repair. Our guide to watering your garden during a drought shows how to limit losses on existing hedges.

Planting and maintaining the hedge

Planting

• Season: planting in autumn, outside frost periods, helps roots establish before the following summer. Early spring also works.
• Soil preparation: loosen the soil deeply and enrich it with organic matter, especially in heavy soils.
• Spacing: it depends on the plant and the density you want; plants should neither crowd each other nor leave gaps. Follow the nursery’s advice for each variety.
• Watering to establish: generous at planting, then regular during the first two summers.
• Mulching: a layer of straw or wood chips limits evaporation and weeds.

Maintaining

Clipping depends on the plant and the shape you want. For dates and techniques, see the guide on when to trim a hedge; for a very long or very tall hedge, hedge trimming can be entrusted to a professional. Remember also to feed the soil and keep an eye out for pests, particularly after a dry summer.

When a hedge is not the right solution

A hedge takes several years to reach its height. If you need an immediate screen, or if space is limited, other solutions exist:

• a privacy screen in wood or composite, installed in a few days;
• a planted trellis for climbing plants, which needs very little width: see fencing and metal trellis;
• a fence backed by a young hedge, which protects while the planting develops.

Combining a structure with planting is often the best compromise. In a wider project, landscape design or garden creation allow the hedge to be placed in harmony with the rest of the grounds.

In Geneva: what is different

The Lake Geneva climate offers fairly mild winters, but the bise can dry out evergreen foliage and batter young plantings, especially on open ground. Summers are increasingly dry: water-thrifty plants such as osmanthus, elaeagnus or a mixed informal hedge are more sensible than thuja. The clay soils common in the canton hold water in winter and crack in summer: loosen the soil and mulch.

Since the sale of cherry laurel has been banned in Switzerland since 1 September 2024, Geneva nurseries offer other options. Needs differ by municipality: open properties on the left bank, such as in Cologny or Vandœuvres, more compact gardens in Carouge.

Hiring a gardener-landscaper

The choice of plants depends on the site, its exposure and your expectations. A gardener-landscaper visits in person, looks at the soil and the bise, then advises you on planting and how to carry it out. The quote is free and without obligation, and you are contacted within 24 hours of your request. To get your project started, you can request a quote.

Frequently asked questions

What is the fastest-growing privacy hedge?

Privet and elaeagnus are among the fastest. In return, they need more frequent clipping to stay under control. Yew grows slowly, but it offers lasting density.

Which hedge best withstands drought?

A mixed informal hedge, or water-thrifty plants such as osmanthus and elaeagnus, cope better with dry summers than thuja. Whatever the plant, regular watering for the first two years and mulching remain essential.

Can you still plant cherry laurel?

No, its sale has been banned in Switzerland since 1 September 2024, because it is one of the invasive exotic plants. If you already have some, find out the rules before replacing it, and avoid dumping clippings in the countryside.

Which hedge keeps its leaves all year?

Yew, osmanthus, photinia and elaeagnus are evergreen. Hornbeam keeps its dry leaves in winter, which maintains a partial screen. For full opacity in every season, choose true evergreens.

When should you plant a privacy hedge?

Autumn is the best time, as the roots settle in before summer. Early spring also works, with closer attention to watering. Avoid periods of frost and intense heat.
