Sowing lettuce, salad
Lettuce is sown in situ in rows from February to October depending on the type and species. Starting early is possible, but you’ll need to protect your seedlings from the cold with cold frames, garden cloches or tunnels.
As for sowing in the summer, germination is difficult above 70°F (20°C), so favor a cooler spot in the garden, even in the shade eventually…
It is always best to sow or plant a smaller quantity of lettuce on a regular basis, so that you may always have crunchy fresh lettuce on hand.
- Spring lettuce – sow in a nursery in February or March.
As soon as frost spells are over, you may remove the tunnel.
- Summer lettuce – sow in situ from April to June.
- Fall lettuce – sow in situ from May to June.
- Winter lettuce – sow in a nursery from August to October.
In all cases, thin sprouts down to one every 10 to 12 inches (25 to 30 cm) as soon as the first leaves appear.
Did you know that salad and lettuce is perfectly suited to growing in pots? You’ll be able to savor it directly from your balcony or terrace.
Planting lettuce from store-bought nursery pots
If you wish to avoid the seedling stage, it is often possible to purchase your lettuce in nursery pots with small leaves.
You can plant them in the ground, either in your vegetable patch or in a garden box on a terrace or balcony.
- Space each plant 12 inches (30 cm) apart and water regularly.
- Once again, just plant what you need and repeat planting regularly.
Harvesting lettuce, salad
- When harvesting, no need to remove the roots: each base will sprout new leaves.
- Best is to use a sharp knife and to slice the head of lettuce at the collar.
Leave the white portion intact, and new leaves will quickly sprout for further harvest.
- Water regularly to keep the soil moist.
- Lettuce must be harvested before it goes to seed.
If you only need a few leaves, feel free to just harvest the ones on the outside from time to time.
Don’t delay to harvest your lettuce, because the crunchier, the better!
Growing lettuce in winter
Choose winter head lettuce varieties such as ‘Imperial Winter’, ‘Winter Marvel’, ‘Batavia Goutte de Sang’, ‘Val d’Orge’ or ‘Brune d’hiver’.
- These can be sown from August to October directly in the ground.
As soon as the cold hits, protect your seedlings and plants with a small greenhouse, a tunnel, or any other device that will help your lettuce grow even though temperatures are below freezing, providing as much light as possible. At right, light snow on lettuce leaves.
