Gardener landscaper in Sion
Sion is the capital of the Canton of Valais and the sunniest city in Switzerland, with over 2,000 hours of sunshine per year.

Frequently asked questions
Which plants thrive in Sion’s climate?
Sion’s hot, dry climate suits Mediterranean and steppe plants: lavender, sage, ornamental grasses, potted olive trees, fig trees and grapevines. Hardy roses, yews and boxwood also do well. Our team recommends proven species to minimise watering and maintenance.
Is automatic irrigation essential in Sion?
It is strongly recommended. Sion receives less than 600 mm of rainfall per year, with particularly dry summers. A drip irrigation system keeps your plantings healthy while saving water. Our gardeners size the installation to suit your garden.
When is the best time to plant in Sion?
Autumn (September to October) is the best planting season in Sion: temperatures drop, humidity returns, and plants have all winter to establish roots before the summer heat. Spring (March to April) also works, provided you ensure consistent watering from the first warm days.
Do you design gardens for vineyard properties around Sion?
Yes, our team landscapes the surroundings of vineyard properties in the Sion region — reception areas, panoramic terraces and ornamental plantings in harmony with the surrounding vineyards. We respect the landscape character of the Valais hillside.
