In the Bouches-du-Rhône, the winter cold changes a lot from one place to another. One winter in ten, it falls to about −6 °C in Marseille and on the coast, −8 °C in the Pays d'Arles, −9 °C around Aix and Aubagne and −11 °C in the Arc and Durance valleys.

We went through thirty winters of Météo-France records, from 1996 to 2026, and compared them with the hardiness of each of our plants. Choose your area below. You will find:

  • the citrus trees that spend the winter outdoors without protection;
  • those that need a fleece on frosty nights;
  • those that stay in a pot.

The lists are kept up to date: only the plants available today are shown with a photo.

Orange trees, clementines, satsumas, yuzus, kumquats and citranges spend the winter outdoors here; lemon trees too, with a fleece on frosty nights. The mistral and salt spray dry out the leaves: plant sheltered by a wall or a hedge.

The soil of the area and the rootstock

According to the soil map, this area mostly has very thin soils over rock, shallow chalky soils and foot-of-slope soils. In practice, the soil is often chalky.

Rootstocks to favour: FA5, then C35.

Your plot may be different. Look at the Géoportail soil map (in French) around your home, then refine with our 5-step test.

The others: in a pot, brought in for the winter

Lemons, limes and less hardy citrus (more tender than −3 °C): in a large pot, outdoors from spring to autumn and brought into a bright, frost-free room for the winter. All our citrus trees.

The plains of the Rhône and the Crau, open to the mistral: −8 °C one winter in ten. Arles, near the Camargue, stays milder (−6.6 °C), Salon-de-Provence falls to −8.8 °C. Orange trees, the hardiest clementines, satsumas, yuzus, kumquats and citranges spend the winter outdoors here; lemon trees and the other clementines need a fleece, against a south-facing wall. A windbreak hedge against the mistral helps a lot.

“Ordinary winter”: half of the winters go colder, the other half less cold. “One winter in ten”: this cold is reached or exceeded in about one winter in ten. Calculations by the Greffeur d'agrumes nursery.

How to read these figures

The hardiness given on our product pages is the cold that an adult, healthy and hardened citrus tree withstands during a short frost. We compare it with the cold that comes back about one winter in ten: a plant listed “without protection” withstands at least that cold. In harsher winters, about three in thirty, keep a winter fleece ready for the coldest nights.

Very harsh winters are still possible. In February 2012, Marignane fell to −9.5 °C and Peyrolles-en-Provence to −14.1 °C. Such cold can burn the leaves or a few shoots of a citrus tree that is only just hardy enough. Wait for spring to see what grows back before pruning.

To understand what helps a tree get through frost, read Understanding citrus hardiness.

Our advice for the Bouches-du-Rhône

  • Avoid hollows. Cold air flows down and collects at the bottom of valleys and in enclosed plains. The records show it: one winter in ten, Aix-les-Milles falls to −12.8 °C, while the centre of Aix stays at −8.6 °C. Plant halfway up a slope or against a south-facing wall, never at the lowest point of the garden.
  • Shelter from the mistral. This cold, dry wind dries out the leaves in winter. A hedge, a wall or a fence on the north-west side protects the tree.
  • Choose the rootstock for your soil. In chalky, dry soil, very common in Provence, FA5 does best. Poncirus is the most cold-resistant and copes with drought better than 4475. In heavy soil, plant on a mound. Our 5-step test helps you choose: Which rootstock should you choose?
  • Water in summer. Summers are dry: a citrus tree in the ground needs regular, deep watering, especially in the first years.
  • Plant in spring, once the frosts are over. The tree then has a whole season to take root before its first winter. From September onwards, no fertiliser and no pruning.
  • Protect young plants on nights below −5 °C during the first years. Put the winter fleece on at each frost and take it off as soon as the frost stops.
  • Mulch in summer only, against drought, without the straw touching the trunk. Pull it away from the foot of the tree at the end of autumn: moisture at the collar encourages phytophthora.

Frequently asked questions

Can I plant a lemon tree in the ground in Marseille?

Yes, with a fleece. Lemon trees withstand about −5 °C, and the coast falls to −6 °C one winter in ten. Plant it against a south-facing wall, sheltered from the mistral, and cover it at each frost. In the Pays d'Arles, do the same. Around Aix and in the Arc and Durance valleys, keep it in a pot. For a safer sour fruit, choose a yuzu or a hardy lemon substitute instead. You will find them in Lemons and lemon substitutes.

Which citrus trees withstand the cold best in the Bouches-du-Rhône?

On the coast, in the Pays d'Arles and around Aix, satsumas, yuzus, kumquats and citranges spend the winter without protection. In the Arc and Durance valleys, at −11 °C one winter in ten, citranges, yuzus and the hardiest satsumas manage without it; the other satsumas and kumquats need a fleece there. They are brought together in Hardy citrus.

What about orange trees and clementines?

They withstand −7 to −9 °C depending on the variety. On the coast, orange trees and clementines spend the winter outdoors without protection. In the Pays d'Arles, so do orange trees and the hardiest clementines; the other clementines need a fleece. Around Aix, the hardiest clementines manage without protection; orange trees and the other clementines need a fleece at each frost, sheltered by a south-facing wall. In the Arc and Durance valleys, orange trees and the hardiest clementines live outdoors with a fleece; keep the other clementines in pots.

My town is not listed: which area should I choose?

Take the nearest area at the same altitude, then compare with the nearest station in the table of readings. Near the sea, winter is milder; in an enclosed plain or at the bottom of a valley, take off one or two degrees.

These figures are guidelines. Your garden may be milder or colder than the nearest station. A question about your plot? Write to us.
