Description
The 'Sierra' Batavia Lettuce is a Lettuce that produces beautiful heads composed of slightly undulate and red-tinged leaves. It is a variety of good taste quality with a sweet and crunchy flavour. In the garden, it withstands heat well and can be sown from February to September for a harvest from May to November.
The seeds contained in this packet are coated with an inert mineral substance that makes sowing easier.
If Lettuce is one of the most popular vegetables (with a consumption of 4.2 kilograms per person per year), it is because of its freshness, crunchiness, and its taste and nutritional qualities. It can be consumed raw in salads but also cooked, for example, to accompany peas.
As the ultimate leaf vegetable, Lettuce is an annual plant that belongs to the large family of Asteraceae. Its Latin name, Lactuca sativa, refers both to the white sap (lactuca) that flows when it is cut and to the fact that it is cultivated (sativa).
It is an essential vegetable in any respectable vegetable garden, and there are so many varieties that it can be grown almost all year round.
Cultivating Lettuce is easy as long as you respect the cultivation calendar for each variety. Its growth is fast, and it thrives in any soil, provided it is rich and remains moist.
Harvest: It is simply done with a knife when it reaches maturity.
Storage: Lettuce can be stored for a few days in the refrigerator, but to enjoy its freshness to the fullest, we recommend consuming it immediately after harvesting.
Gardener's tip: During hot summer weather, lettuces exposed to direct sunlight tend to wilt miserably. To prevent this phenomenon, consider protecting them from intense rays using inverted crates. In our garden, summer lettuces are not cultivated in rows but interplanted throughout: at the base of climbing beans, in the midst of cucumbers and squashes whose foliage provides beneficial shade.

Planting and care
Sowing:
Lettuce germination occurs at a temperature of about 18° and takes an average of 10 days.
Sowing is done from February to September for a harvest from May to November.
On well-prepared and loosened soil, make furrows spaced 30cm (12in) apart, with a depth of 0.5cm. Sow in rows, spacing the seeds 4cm (2in) apart and cover. After germination, when the plants are well developed, thin them out to leave one plant every 30cm (12in).
If your vegetable garden is often targeted by slugs and snails, we recommend sowing under shelter, in small pots, and then transplanting the well-developed plants to the garden.
Cultivation:
Lettuce is not a very demanding vegetable, but it still requires humus-rich soil, otherwise it tends to bolt prematurely. It is advisable, preferably in autumn, to apply a moderate amount of well-rotted compost by raking it to a depth of 5cm (2in), after loosening the soil as you would for any vegetable crop. It prefers slightly acidic to neutral soils (pH between 5.5 and 7.5).
During cultivation, remember that lettuce prefers moist soil and make sure to water it regularly.
Lettuce is a good companion plant and can easily be intercropped with slower-growing vegetables such as beans, tomatoes, cucumbers... Just avoid planting it next to corn.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
