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

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.
For limited space or a smaller, more accessible leaf crop.
Tick off your supplies →Biscia Rossa has bronze-green, deeply cut leaves and is grown as cutting lettuce. Its Italian alias describes curled leaves for cutting.

Use a portion of young leaves as a salad base. The loose form makes it easy to mix with differently shaped leaves.
Zaai kleine opeenvolgende hoeveelheden en houd de grond vochtig. Een plek met wat halfschaduw kan bij warm weer praktisch zijn.
Cut young, usable leaves and retain the growing point if you want regrowth. Harvest before leaves become too coarse for your salad.
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.
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.
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.
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.
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.
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.
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.
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.
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.
