Sustainable Seed Company Merveille Des Quatre Saisons Lettuce

Heirloom seeds are open-pollinated varieties that have been passed down through generations. Because they are not hybrids, you can save the seeds from your harvest to replant in future seasons, and they will grow true to the parent plant.

To maintain viability, store unused seeds in a cool, dark, and dry place. An airtight container kept in a refrigerator or a temperature-controlled pantry is ideal for preserving germination rates over time.

While the bulk quantity suggests large-scale planting, this variety performs well in containers as long as they are deep enough to accommodate root growth. Ensure your pots have adequate drainage and receive consistent moderate watering.

Merveille Des Quatre Saisons is known for its cold tolerance, but it is not frost-proof. It is best suited for mild winter climates or early spring planting; if you live in an area with hard freezes, you may need to use a cold frame or row cover to protect the young plants.

You can expect this lettuce to reach full maturity in approximately 60 days. However, you can begin harvesting outer leaves earlier as 'baby greens' if you prefer a continuous supply.

While the specifications note peat soil, it is not strictly required. This lettuce thrives in well-draining, nutrient-rich soil; if you aren't using peat, ensure your garden bed or potting mix is amended with compost to provide a similar moisture-retentive environment.
