In the Aveyron, winters are harsh for citrus trees, and the cold changes from one place to another. One winter in ten, it falls to about −11 °C in the Tarn valley and the Rougier de Camarès, −14 °C around Villefranche-de-Rouergue, and −15 °C on the Causses (limestone plateaus), in the Lot valley, on the Aubrac and in Rodez.

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.

“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, Rodez fell to −16.1 °C and Laguiole to −17.5 °C; in January 2004, Cornus recorded −17.9 °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 Aveyron

  • Choose very hardy citrus. With −14 to −15 °C one winter in ten over most of the département, citranges, Yuzu and Yuzu 3 spend the winter outdoors, and the other yuzus (Yuzu 30, thornless, Tada Nishiki) and the hardiest satsumas with a fleece; in the Tarn valley, yuzus and the hardiest satsumas manage without a fleece, and orange trees and kumquats cope with one. The other citrus trees are grown in pots, brought in for the winter.
  • Avoid hollows. Cold air flows down and collects in low ground. The records show it: at Montlaur, two neighbouring stations differ by two degrees one winter in ten (−11.4 °C and −13.5 °C). Plant halfway up a slope or against a south-facing wall, never at the lowest point of the garden.
  • Take altitude into account. On the Aubrac, Laguiole (1,030 m) falls to −16.0 °C one winter in ten, while Entraygues-sur-Truyère, in the valley, stays at −11.5 °C.
  • Choose the rootstock for your soil. On the Causses, the soil is chalky: plant on a mound. Poncirus is the most cold-resistant; in chalky, dry soil, FA5 does better. Our 5-step test helps you choose: Which rootstock should you choose?
  • Plant in spring, once the frosts are over. The tree then has a whole season to take root before its first winter.
  • 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 Rodez?

No. Lemon trees withstand about −5 °C, and Rodez falls to around −10 °C in an ordinary winter. Keep them in pots, brought in for the winter. For a sour fruit in the ground, choose a hardy lemon substitute instead, with a fleece. You will find them in Lemons and lemon substitutes.

Which citrus trees withstand the cold best in the Aveyron?

Citranges, Yuzu and Yuzu 3, which withstand −15 °C: they spend the winter outdoors without protection throughout the département. In the Tarn valley, the other yuzus and the hardiest satsumas also manage without it; elsewhere, they need a fleece on frosty nights. They are brought together in Hardy citrus.

What about orange trees and clementines?

They withstand −7 to −9 °C depending on the variety. In the Tarn valley and the Rougier de Camarès, orange trees and the hardiest clementines live in the ground with a fleece, against a south-facing wall; the other clementines stay in pots. Elsewhere, that is not enough for the Aveyron: keep them in pots, brought in for the winter.

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. Take off about one degree for every 150 m of extra altitude, and one or two degrees if you are in a hollow.

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