Batavia lettuce ‘Rouge Grenobloise’: Sowing, planting and harvest calendar
How do you sow 'Rouge Grenobloise' lettuce under cover?
Sow your 'Rouge Grenobloise' lettuce under cover to raise plants when outdoor conditions are less favourable. Choose the timing according to your climate, available shelter and the seed packet. This Batavia lettuce forms a head. At the sowing stage, the aim is to raise healthy young plants rather than immediately give them their final planting distance.
Prepare clean seed trays, pots or modular trays with holes for water to drain away. Use fine seed compost that you have moistened beforehand. Sow thinly and cover the seeds lightly to the depth recommended by the supplier. If using modules, avoid keeping several crowded seedlings in the same cell.
Keep the containers in bright shelter and check moisture. The compost should stay moist without standing water. Ventilate when conditions allow and avoid overheating, which can interfere with lettuce germination. If seedlings in a tray become crowded, carefully move them into individual pots once they are sturdy enough to handle. Preserve their roots and let the young plants strengthen before gradually accustoming them to outdoor conditions.
