Your gardener-landscaper in the Canton of Valais

Valais is a canton of striking contrasts. Between the Rhone plain at 500 m altitude and summits over 4,000 m, gardening conditions change dramatically. The main valley enjoys the driest and sunniest climate in Switzerland — Sion records over 2,000 hours of sunshine per year — while the lateral valleys experience harsh winters and short summers. The alluvial soils of the Rhone plain, enriched by alpine sediment, are among the most fertile in the country. SOS Jardin’s team masters these unique conditions — contact us for a free quote.

Gardening specifics in the Canton of Valais

Valais has a climate unlike anywhere else in Switzerland, shaped by contrasts in altitude, exposure and humidity. The Rhone plain between Martigny and Brig is the driest part of the country, with barely 600 mm of annual rainfall in Sion — less than some Mediterranean regions. This relative aridity is offset by exceptional sunshine (over 2,000 hours per year in central Valais) and by the historic network of bisses, open-air irrigation channels that have criss-crossed the hillsides since the Middle Ages.

Gardening conditions vary dramatically depending on altitude and aspect:

Rhone plain (450-600 m): semi-arid climate, fertile alluvial soils, growing season from March to November. Possible to grow apricot trees, fig trees, ornamental vines and Mediterranean plants.
Hillsides (600-1,000 m): vineyards, sloping terrain, schist or moraine soils. Retaining walls and terracing are often essential.
Lateral valleys and mountain zone (1,000-1,500 m): alpine climate, short season (May to October), frequent frost until May. Chalet gardens with very hardy species.

The foehn is a distinctive weather phenomenon in Valais: this hot, dry wind descending from the Alps can raise temperatures by 10 to 15 °C in a matter of hours and rapidly desiccate plantings. Valais gardeners anticipate these episodes and design gardens capable of withstanding them.

Main towns served

Sion — Capital of Valais and the sunniest city in Switzerland, Sion is dominated by the hills of Valere and Tourbillon. Gardens on the plain benefit from rich alluvial soil and an almost Mediterranean summer climate, allowing the cultivation of apricot trees, fig trees and lavender. Residential development around Bramois and Uvrier drives sustained demand for garden creation.

Sierre — Nicknamed the “City of the Sun”, Sierre marks the linguistic border and enjoys record sunshine. Gardens sometimes harbour near-Mediterranean species. The hillsides of Noble-Contree and Miege, covered in vineyards, feature steep terrain where landscaping requires terracing expertise.

Martigny — Located at the bend of the Rhone, Martigny is a crossroads between the Rhone valley and the Val d’Entremont leading to the Great St Bernard. Gardens can suffer from the foehn, a hot dry wind that can desiccate plantings in a matter of hours. A well-sized irrigation system is essential.

Monthey — The main town of the Chablais valaisan, Monthey benefits from a more humid climate than central Valais thanks to the proximity of Lake Geneva. The soils are heavier and more clayey, favouring hedge plants and deciduous trees.

Visp (Viege) — Centre of the German-speaking Upper Valais, Visp experiences semi-arid conditions in summer and cold winters. Gardens must be designed to withstand large temperature swings, with hardy species and an adapted irrigation system.

Brig (Brigue) — Gateway to the Simplon, Brig sits at 680 m altitude with a marked mountain climate. Gardens have a shorter growing season (May to September) and require species resistant to winter frosts that can drop below -15 °C.

Why choose a local gardener in Valais

Expertise in drought management. Central Valais is the driest region in Switzerland, with barely 600 mm of annual rainfall in Sion. A Valais gardener knows how to design water-efficient gardens using xerophilic plants, appropriate mulching and high-performance automatic irrigation systems. They also know about the bisses — traditional irrigation channels — and connection possibilities.

Managing temperature extremes. Valais experiences extreme temperature swings: up to 35 °C in summer in Sion and -15 °C in winter. A local professional selects species capable of withstanding these variations and plans the winter protection needed for sensitive plants.

Knowledge of alpine soils. Valais soils are unique: alluvial and fertile on the Rhone plain, schist and poor on the hillsides, moraine at altitude. A local gardener adapts plantings and soil amendments to the exact nature of your terrain.

Showcasing local heritage. The best Valais landscapers incorporate local materials and craftsmanship into their projects: dry-stone walls, Valais larch wood, native species plantings. They create gardens in harmony with the surrounding alpine landscape.

Frequently asked questions

Which plants tolerate drought in central Valais?

The semi-arid climate of central Valais favours Mediterranean and xerophilic species: lavender, rosemary, santolina, ornamental grasses (stipa, blue fescue), sedums, thyme, yarrow and echinacea. Suitable trees include the downy oak (naturally present in Valais), Scots pine, amelanchier and field maple. A Valais landscaper can design a garden requiring minimal irrigation using these species.

Can you garden year-round in Valais?

On the Rhone plain (Sion, Sierre, Martigny), the gardening season runs from March to November. The dry, sunny winters even allow certain pruning and construction work in December and January. However, in the lateral valleys and at altitude (above 1,000 m), the active season is limited to May through October. Late frosts can occur until the end of April on the plain and into early June at altitude.

Is automatic irrigation essential in Valais?

In central Valais, an irrigation system is strongly recommended for any garden with lawn or non-xerophilic ornamental plantings. With just 600 mm of rain per year and summer temperatures regularly exceeding 30 °C, an unwatered lawn turns yellow by mid-June. A well-designed automatic irrigation system optimises water consumption while keeping your garden green.

How do you protect a garden from the foehn?

The foehn, a hot dry wind descending from the Alps, can desiccate a garden in hours and damage young plantings. Solutions include creating windbreak hedges with resistant species (hornbeam, dogwood, privet), installing temporary shade sails and increasing irrigation on foehn days. An experienced Valais gardener anticipates these episodes and adapts plantings accordingly.

Do Valais gardeners also work on second homes in mountain resorts?

Yes, SOS Jardin offers services for second homes and chalets in mountain resorts. They provide seasonal maintenance, winter preparation for plantings and spring restoration, even in the owners’ absence. Specify the altitude and accessibility of your property when requesting a quote.

Can bisses be used to irrigate my garden?

Bisses are a unique part of Valais heritage. Some are still active and feed communal irrigation networks. If your property borders an active bisse, it may be possible to connect to it by contributing to the consortage (the association of owners that manages the bisse). However, for most modern gardens a programmed automatic irrigation system remains the most practical and water-efficient solution, particularly drip irrigation.

Which fruit trees grow best in Valais?

Valais is the leading fruit-growing canton in Switzerland, with a centuries-old tradition. On the Rhone plain (Martigny to Sierre), apricot trees (Luizet, Bergeron varieties), Williams pears, apple trees and cherry trees produce excellent results. Fig trees thrive in sheltered spots in Sion and Sierre. In the Chablais (Monthey), the wetter conditions suit apple and plum trees. At altitude (above 800 m), apple trees and walnut trees are the best adapted. A Valais gardener can advise you on the local varieties best suited to your situation.

Do you need a permit to build a terrace or retaining wall in Valais?

In Valais, outdoor structures such as covered terraces, pergolas and retaining walls over 1 metre in height generally require a building permit. Setback distances from property boundaries and landscape integration standards (particularly strict in vineyard zones and protected villages) must be respected. Each Valais municipality has its own building regulations — your professional landscaper will guide you through the process.
