🌱 Sowing & growing
1. When and how should you sow your seeds?
Each product page indicates the recommended sowing period. On our website, we also specify the ideal temperature, the possible need for stratification, and the optimal period depending on the climate. In general: annuals in spring (after the last frosts); perennials/trees in autumn or spring (sometimes after a period of cold). To learn more, visit the blog The Seed Corner.
2. How do I know whether a seed needs stratification?
Stratification (cold, moist treatment) breaks the dormancy of many perennials, shrubs, and woodland species. This is indicated on each product page. Also consult our guide Everything You Need to Know About Stratification.
3. Should seeds be soaked before sowing?
Useful for hard-coated seeds (lotus, peas/legumes, and certain flowers): soak them for a few hours to overnight in lukewarm water. The product page indicates whether this step is necessary.
4. What is the ideal sowing depth?
As a general rule: very small seeds on the surface (a thin layer of potting soil); medium-sized seeds at 2–3× their diameter; large seeds deeper. Water gently so they are not displaced.
5. What are the ideal conditions for good germination?
Suitable temperature (often 18–22 °C for vegetables), a moist but not waterlogged substrate, soft/indirect light, and good ventilation to limit mold.
6. Do you offer advice for beginners?
Yes. Clear, illustrated articles on starting a vegetable garden, succeeding with your sowings (indoors/outdoors), and basic techniques (stratification, soaking, transplanting, etc.). Free access: Gardening Tips & Permaculture.
🌾 Growing & care
7. Which varieties are suitable for balconies or small spaces?
Varieties for pots/planters (herbs, flowers, compact vegetables). Discover our kits: Terrace & balcony flower seed kit and Balcony/terrace vegetable garden seed kit. Each product page specifies whether the variety is suitable for pots, balconies, or open ground.
8. What are the sowing periods by season?
Spring: the ideal season for most vegetables, annual flowers, herbs, and fast-growing perennials.
Autumn: ideal for trees, shrubs, perennials, and species that benefit from natural winter stratification.
Summer: suitable for staggered sowing (lettuce, radishes, green manure) to extend harvests.
9. How to harvest and store your own seeds?
Select the best specimens (shape, vigor, taste). Avoid damaged or overly late fruits. Let them ripen completely, harvest in dry weather, sort them, and store them in paper bags or airtight containers away from moisture and heat. Since our varieties are reproducible, you can resow them year after year.
📅 What to sow, season by season?
10. What to sow in spring?
Spring is the broadest sowing season in our catalog. It's the preferred time for summer vegetables (tomatoes, squash, cucumbers, peppers, eggplants), the vast majority of annual flowers, and most herbs: the soil warms up, frosts recede, and young plants have the entire growing season to develop before the following winter. It's also the best window for starting perennials and trees that have already received their winter cold period (stratification): their seeds are then ready to germinate.

11. What to sow in summer?
Summer isn't just for garden maintenance: it's also the time for succession sowing. In particular, it's when to sow short-cycle vegetables to extend harvests into autumn (radishes, carrots, beets, late-season cauliflower), fast-growing annual herbs that tolerate heat well (basil, coriander, parsley), as well as biennials such as foxglove and wallflower, sown in a nursery from June to July to flower the following year. It's also the ideal time to start tropical species grown in pots, which have no marked seasonal dormancy.

12. What should I sow in autumn?
Autumn is the most natural season for two major groups of plants to sow. First, garlic and wild alliums, which need a period of cold to develop properly and are traditionally planted from October to December. Second, trees, shrubs, and perennials with hard seeds, which need cold stratification to germinate: when sown outdoors in autumn, winter does this work naturally, without artificial intervention. This is also the time to sow hardy annual flowers (cornflower, poppy, love-in-a-mist, opium poppy), which overwinter as young plants and flower earlier and more vigorously the following spring.
The full selection can be found in Autumn sowing, including our White Garlic seeds and our Cornflower seeds.
13. What can I sow all year round?
Some plants do not have a true seasonal dormancy and can be sown indoors at any time of year, as long as they receive some warmth and light. This is the case for fast-growing annual herbs such as basil, parsley, chives, and dill, which can be resown in pots every few weeks for a continuous supply. The same applies to tropical and subtropical species grown in pots (tea plant, stevia, dragon fruit, weeping fig...), which grow indoors without being constrained by the outdoor season.
