Vegetable gardens in the French overseas territories: choosing a calendar suited to your garden

Start with the territory and location

The French overseas territories encompass very different climates. Météo-France describes, in particular, tropical regimes, the humid equatorial climate of French Guiana, and the cold oceanic climate of Saint-Pierre-et-Miquelon. Even in French Polynesia, the general distinction between two seasons does not apply identically to all islands.

To find a calendar, note the territory, municipality or sector, altitude, and slope. Then compare the conditions of the reference with those of your plot: a guide established for a high-altitude zone is not sufficient for organising a coastal vegetable garden.

Which benchmarks should be compared in other territories?

The Météo-France overview helps distinguish the contexts below. The links lead to local meteorological services for examining your sector and current conditions; they are not planting calendars.

To choose a vegetable, next look for a horticultural reference matching the territory, sector, and species. A weather forecast provides expected conditions; it is not sufficient to determine the growing period for a variety.

In La Réunion: distinguishing altitudes and slopes

Météo-France highlights the major influence of Réunion’s relief: the eastern part may remain well-watered during the so-called dry season. Therefore, check the rainfall in your sector before deducing irrigation needs.

The Tropilég de La Réunion guide, dated 2017, links the diversity of tropical and temperate crops to climatic and altitude differences. The pea provides a more specific example: this cool-season plant is cultivated in high-altitude zones during the austral winter. This benchmark applies to this species and context; it does not provide dates for all vegetables on the island.

In Mayotte: assessing the constraints of the rainy season

The Tropilég Mayotte guide describes vegetable production concentrated mainly in the dry season. It notes that during the rainy season, heat, heavy rainfall, humidity, and pest and disease pressure combine. This 2017 professional assessment helps identify key points to check before a trial in a home garden.

The same source highlights the challenges for vegetables requiring cooler conditions at low altitudes and more favourable conditions for certain crops at higher elevations. Verify the species’ requirements before ordering seeds: simply shifting the months of a calendar for metropolitan France does not resolve this discrepancy.

In Guadeloupe: comparing growing areas

The Tropilég Guadeloupe guide, dated 2017, distinguishes the hilly terrain of Basse-Terre from the plains of Grande-Terre. It describes the cooler, wetter highlands of Basse-Terre and the drier leeward west coast. These differences explain why a calendar must specify the sector it covers.

Before following a local guide, compare the altitude, exposure to rainfall and water access of the site it describes with your own. Adapt these professional observations to your garden’s equipment and conditions.

Verify a reference before sowing

Prepare a small sheet for each crop with the species and variety name, the sector to which the advice applies, the suggested season, and the cultivation method. Look for constraints related to heat, coolness, water, and plant health in the reference. Also check its date: the professional guides cited here provide horticultural examples but do not fully describe the current conditions of your garden.

Supplement this with current observations and local weather forecasts. Keep a record of sowing, seedling emergence, rainfall or irrigation, observed damage, and harvest. Starting with a small trial allows you to compare the advice with the results from your location before committing an entire bed.

Using other guides within their geographical scope

The monthly calendars and other cultivation guides on this site provide benchmarks for metropolitan France. To use them in the French overseas territories, verify each date and variety separately with a suitable local reference. This guide offers a selection method and three documented examples; it is not a sowing calendar for all territories.

The sowing guide helps assess starting conditions; the irrigation guide covers monitoring moisture. For a plot with an uncertain history, also consult the questions to ask before setting up a vegetable garden in urban soil. Check that the methods they describe suit your crop, soil and local conditions.
