This growing advice helps you choose. Your variety, growth stage, weather and conditions in your space determine the actual timing.

A good start

Sowing under cover and raising seedlings

Koel voorzaaien of direct zaaien · Lettuce

Februari–augustus, naar rasZaai op een lichte, niet hete plek. Een warme zolder kan te warm zijn.

Germination and temperature
Koel en licht laten kiemen; veel sla kiemt slecht boven ongeveer 25 °C.
After emergence
Zet opgekomen sla licht en luchtig; voorkom hoge kastemperaturen en uitdroging.
Pricking out and potting on
Zaai in modules of verspeen hanteerbare zaailingen naar een eigen cel. Houd de kluit bij uitplanten heel.
Hardening off and planting out
Laat binnen opgekweekte planten geleidelijk aan zon, wind en buitentemperatuur wennen; zet ze bij koude nachten weer beschut. Plant stevige jonge planten uit; houd het groeipunt vrij en bescherm tegen slakken.

Kies een voorjaar-, zomer- of winterras. Aspergesla heeft een ander oogstdoel dan kropsla; volg het eigen rasvenster.

Short rows in a garden bed

Met een kleine rij sla maak je de verzorging overzichtelijk. Kies het juiste seizoen, houd het bed vrij van onkruid en volg het blad. Een volgende portie kun je plannen wanneer je ziet hoeveel je werkelijk gebruikt.

  1. Prepare a fine soil surface and remove weeds.
  2. Sow or plant at the spacing for the chosen type.
  3. Keep the germination and root zones moist and harvest according to leaf quality.

For anyone with a small bed or a space available after another harvest.

Een kleine saladebak bij de deur

Losse bladsla is prettig in een brede pot. Je kunt alleen oogsten wat je nodig hebt en ziet makkelijk wanneer een volgende zaai nodig is. Houd genoeg ruimte voor licht en lucht tussen de rozetten.

  1. Kies losse bladsla of een bevestigd compact kropje.
  2. Gebruik een pot met afwatering en geschikte potgrond.
  3. Oogst buitenblad of hele kroppen volgens het gekozen type.

For limited space or a smaller, more accessible leaf crop.

Take a closer look

Even a patio planter can be a picking garden

Use a roomy container with drainage holes and keep the potting compost evenly moist. Give the plants space and gradually pick the outer leaves.

Choose by flavour, shape and use

Chou de Naples: Chou de Naples is a Batavia lettuce with lightly curled leaves and a firm, not fully closed heart. Its name does not make it a cabbage crop. Use the crisp leaves on bread or in a substantial main-meal salad. Outer leaves and a whole heart provide different portion sizes.

The product source describes a fresh, mild flavour. The crisp leaf texture also contributes to the eating experience.

Soissons: Soissons is a French Batavia lettuce with large, firm green hearts. The lightly curled leaves fill a generous bowl. Use the leaves in a summer salad or as a crisp layer on bread. A whole heart can be divided between several preparations.

The source describes the flavour as fresh and mild, with crisp leaves that are more tender than typical iceberg lettuce.

Queue de Truite: Queue de Truite has green leaves with red speckles and forms a small cos lettuce. It is a Lactuca lettuce, despite the retail alias 'Witloof panaché'. Use small leaves whole or cut a heart into strips. The speckles remain most recognisable when served fresh.

The source describes crisp leaves but no distinct aroma profile. The name does not justify a chicory or witloof flavour.

Speckled Amish: Speckled Amish is a traditional butterhead lettuce with light green leaves and reddish-brown speckles. The heart stays loose and the leaves are tender. Use the tender leaves in larger pieces and add dressing only shortly before eating. This keeps the speckled pattern visible.

The source does not confirm a distinct aroma. 'Mild appearance' describes the look and is not used as evidence of flavour.

Choose the type to suit your harvest

Hearting, cos and loose-leaf lettuces are harvested differently. A closed heart needs more time and space than young picked leaves. Choose a type that suits your cooking routine and look for a cultivar intended for cool growing for autumn.

A small, sound start

Sow small batches in clean compost and give emerging seedlings light. Lettuce germinates less well in great heat; choose a cooler sowing position then. Hearting lettuce can be started in modules, while a thinly sown leafy edging is manageable directly in the bed.

Light and soil that can drain

Choose a bright spot and prepare a fine enough surface for the small seeds or young rootballs. Water must be able to drain away after rain. In a pot, check that the drainage holes are clear; a layer of wet soil does not help produce a healthy leaf harvest.

Care for the young leaves

Thin young plants in good time or plant individual rootballs at the cultivar's spacing. A lettuce does not form a good heart if its leaves compete with too many neighbours. Keep the soil moist and remove weeds that shade small lettuce seedlings.

Harvest for quality

Cut a filled-out heart all at once or pick young outer leaves from loose-leaf lettuce. Leave the growing centre if you want to continue harvesting. Assess the leaves, not just a planned date: warmth can change the harvest more quickly.

Recognise what the leaves tell you

Slugs can eat almost all of the first young plants. Look for feeding damage and hiding places early. A central stem rising quickly indicates bolting; the leaves may become more bitter. Sow another small batch in a more suitable position or a better season.

Fresh leaves start with a small picking

Harvest at a cool time and keep the leaves cool after picking. Wash them before use and remove damaged parts. A small fresh portion wastes less than harvesting a whole container when you only need a handful.

Make room for the next round

Record sowing and the first harvest so you can compare what works in your space next season. Do not leave an empty row unplanned for long. A new batch within a suitable window gives a better spread than hoping overmature leaves will become young again.
