Save Your Own Seeds: A Mauritian Planter's Guide to Free Seeds for Next Season
By Ti Bazar
Free Seeds from Your Own Garden
Every season, planters across Mauritius spend money on new packets of seeds. But some of the best seeds are already growing in your garden for free. Saving your own seeds cuts costs, builds plants that are better adapted to your plot, and helps preserve the local varieties that make Mauritian cooking what it is. It is also true Zero Gaspiyaz: nothing wasted, everything reused.
Here is how to collect, dry, and store seeds from your own harvest, the right way for our warm, humid climate.
Why Save Seeds?
- Save money — One ripe tomato or a few dried okra pods can give you dozens of seeds for next season.
- Stronger, adapted plants — Seeds from the plants that thrived in your soil and survived our heat, rain, and pests pass on that resilience. Year after year, your line gets tougher.
- Preserve local varieties — Heritage crops like Giraumon (local pumpkin), Lalo (Okra), Margoze (Bitter gourd), and old local tomato types are part of our food heritage. Saving their seeds keeps them alive.
- Share and swap — Trade seeds with neighbours and fellow planters to grow more variety for free.
First, Know Your Seeds: Open-Pollinated vs Hybrid
This is the one rule that decides everything. Only save seeds from open-pollinated (also called heirloom or traditional) varieties. These grow "true to type" as the seed produces the same plant as the parent.
Seeds saved from F1 hybrid plants (often the most expensive packets) will not grow true. The next generation can be weak, oddly shaped, or unproductive. If your seed packet says "F1" or "hybrid", enjoy the harvest but buy fresh seed next time. Most traditional local varieties sold loose at agricultural co-ops are open-pollinated and perfect for saving.
Easy Crops to Start With
Begin with self-pollinating crops because they rarely cross with their neighbours, so the seed stays pure with almost no effort.
| Crop | Difficulty | How to collect |
|---|---|---|
| Haricot (Beans) / Pois | Easiest | Let pods dry brown on the plant, then shell |
| Lalo (Okra) | Easy | Leave a few pods to dry hard and brown, split open |
| Piment (Chilli) | Easy | Let fruit fully ripen red, scrape out and dry seeds |
| Tomato | Easy | Use the fermentation method (below) |
| Bringelle (Eggplant) | Moderate | Let one fruit over-ripen until dull and yellowish, scoop seeds |
| Giraumon (Pumpkin) / Calbasse | Moderate | Scoop, wash off pulp, dry (watch for cross-pollination) |
| Concombre (Cucumber) | Moderate | Let fruit go fat and yellow, ferment like tomato |
| Margoze (Bitter gourd) | Moderate | Let fruit ripen orange and split, take the red-coated seeds |
Leafy crops like Laitue (Lettuce) and Cotomili (Coriander) are also easy — just let a few plants "bolt" (flower and go to seed) instead of harvesting them.
How to Save Seeds, Step by Step
Dry-Seeded Crops (beans, okra, chilli)
- Choose your healthiest, most productive plants; never your weakest.
- Leave the pods or fruit on the plant until they are fully mature and starting to dry.
- Bring them indoors to finish drying in a shady, airy spot.
- Shell or split the pods and separate the seeds from the chaff.
Wet-Seeded Crops (tomato, cucumber)
Tomato and cucumber seeds are wrapped in a gel that stops them sprouting inside the fruit. A short fermentation removes it and kills some seed-borne diseases:
- Scoop the seeds and gel into a glass or cup. Add a little water.
- Leave it on the counter for 2-3 days, stirring once a day. A layer of mould may form on top and that is normal.
- Add more water and stir. The good, heavy seeds sink; pulp and hollow seeds float off.
- Pour off the floaters, rinse the good seeds in a sieve, and spread them out to dry.
Drying Seeds Properly
This step matters most in Mauritius, because our humidity is the enemy of stored seed.
- Dry seeds in a shady, well-ventilated place; never in direct sun or near a stove, as heat kills them.
- Spread them in a single layer on a plate, paper, or fine mesh.
- They are ready when they are hard and snap rather than bend. A bean should be too hard to dent with a fingernail.
Storing Seeds So They Last
- Only ever store fully dry seeds. Even slightly damp seeds will mould.
- Use paper envelopes inside an airtight glass jar, or small zip bags.
- Label everything with the crop name, variety, and the date collected; you will not remember in six months.
- Add a small twist of paper holding dry rice or a silica sachet to the jar to absorb any moisture.
- Keep the jar somewhere cool, dark, and dry. The bottom shelf of a fridge is ideal for long-term storage.
Most vegetable seeds stay good for 2-4 years when stored well. Beans, tomato, and chilli are especially long-lived; onion and leek seed is best used within a year.
A Word on Cross-Pollination
Some crops cross easily with their relatives, so the saved seed may surprise you. The squash and gourd family (giraumon, calebasse, cucumber, margoze, courgette) cross readily if grown close together. To keep a variety pure, either grow only one type of that family at a time, or simply enjoy the mix and see what you get. Self-pollinating crops like tomato, beans, chilli, and lettuce stay true with no special effort — which is why they are the best place to start.
Share the Harvest
Seed saving has always been a community tradition. Swap your saved seeds with neighbours and other planters to build variety for free, and help keep our local crops thriving for the next generation.

Every saved seed is a small act of independence and a step towards Zero Gaspiyaz. When your harvest comes in, share the surplus with your neighbours on Ti Bazar.
