Terms of use
Last updated: 29 September 2026
These terms govern the use of the Semiterra website (semiterra.com), published by Veltone SAS. By using the website, you accept them.
The service
Semiterra tells you what to sow, plant and harvest in the vegetable garden, and when, based on the climate and altitude of your town. The website also offers plant pages, monthly calendars by climate and a blog. Access is free and requires no sign-up.
Nature of the information
The dates given are averages computed from historical climate data (1991-2020) and reference growing calendars. They are provided for information only. The weather of the year, the microclimate of your garden (exposure, valley floor, lakeside), the soil and the variety grown may call for adjustments. Companion planting is shown with its level of evidence: much of it rests on tradition rather than scientific studies.
Articles written with the help of artificial intelligence
The blog articles are written with the help of artificial intelligence from Semiterra's data, then reviewed by our team before publication. Their illustrations are generated by artificial intelligence. Despite this review, an error remains possible: please let us know if you spot one.
Use of the website
You agree to use the website for its intended purpose. In particular, the following are prohibited: systematic or automated extraction of content and data, any attempt to disrupt the website, and any reproduction of content without authorisation (see the legal notice).
Liability
Veltone SAS strives to provide accurate information and an available website, without being able to guarantee it. It cannot be held liable for the results of your crops, for losses due to frost or weather, or for an interruption of the website. Links to third-party websites are provided for information; Veltone SAS is not responsible for their content.
Personal data
Data processing is described in our privacy policy.
Changes to these terms
These terms may be changed at any time; the applicable version is the one published on the website on the day of your visit.
Governing law
These terms are governed by French law. Failing an amicable settlement, any dispute falls within the jurisdiction of the competent French courts.
