It has strong leaves with a slightly bitter, strong taste. Alternatively, you can also choose 'Wintermarie'. An Austrian, traditional variety is 'Neusiedler Gelber Winter'. 'Trémont' has beautiful red spots of color and can be sown both in autumn and early spring.

Sowing Winter Lettuce: Tips on Timing & Sowing

Most winter lettuces need to be sown in summer so that they have most of their growth behind them by fall. When fully grown, the plants are perfectly hardy. However, you can also sow in late fall, as the seedlings are already hardy. However, the seedlings are usually not quite as large, which is why the harvest is quite small. As it is often very dry in the summer months, you should make sure to water regularly to prevent emergence problems.

• Winter lettuce is sown outdoors from July to September. The heads can be harvested throughout the winter. As winter lettuce is a light germinator, the seeds should only be pressed on.
• Lamb's lettuce can be harvested in the fall (until October). For this, it is sown from July to August. For a later harvest from November to January, you must sow in September. Make sure to sow the plants in a wide-spread pattern. You can find out How to Sow, Care for and Harvest Lamb’s Lettuce for a successful harvest in this article.
• Endive can be harvested well into November as it can withstand light frosts. To do this, the winter lettuce seeds should be sown at the end of July to the beginning of August. Separate the young plants after emergence to approx. 30 x 30 cm/11,8 x 11,8 in.
• Postelein/winterpurslane can be sown broadly from September to March. As light germinators, the seeds should only be pressed down. The small rosettes can be somewhat denser and do not need to be singled out. You can Read All About Growing Winter Purslane here.
• Sugar loaf is sown from June to August. Separate the winter lettuce later to 20 x 30 cm/7,9 x 11,8 in. Sugar loaf is ready to harvest from October, but can easily be left in the field all winter and only harvested when needed.
• With radicchio, make sure you get a late variety for winter cultivation. For example, 'Roter Veroneser' is suitable here. Sow at the beginning of July in rows of 12 x 30 cm/4,7 x 11,8 in.
• Orchid lettuce is a particularly beautiful, sweet and mild winter lettuce variety that is a variation of radiccio. The white leaves with red dots look particularly beautiful in a bare winter bed. Orchid lettuce is sown for an autumn harvest from mid-June. The winter lettuce variety can then be harvested from the end of September.
• If you want to grow lettuce as winter lettuce, it is best sown from August to October. Although you can also pre-grow winter lettuce indoors, it is easiest to sow it directly into the bed. The individual plants should be quite close together as they are better protected from frost and cold. Sow the winter lettuce seeds over a wide area to create a dense carpet of lettuce later on. As lettuce is a light germinator, the seeds should only be pressed down and not buried.

Winter Lettuce in a Raised Bed

You can also grow various winter lettuces in raised beds. In addition to lettuce, lamb's lettuce also grows well in raised beds. However, the soil freezes more quickly here as the raised beds are more exposed to the cold from the sides. It can help to wrap the raised beds with insulating fleece or fir branches. Individual heads of lettuce or rosettes can also be covered with fleece in severe sub-zero temperatures. Another problem could arise in summer when sowing, as raised beds dry out more quickly than normal beds. Therefore, always make sure to water regularly after sowing.

Mixed Crop Planting Plan With Winter Lettuces: Examples & Ideas

With winter lettuces, you can plant and use your bed all year round. They are the perfect successor crop for heavy feeders, as most lettuces are weak or medium feeders. Although the soil is covered, it is not used as much. You can find examples of your planting plan with winter lettuces here.

Harvesting and Storing Winter Lettuce

You can find tips on harvesting winter lettuce here, as you can harvest and enjoy some varieties, such as winter postelein and lamb's lettuce, several times. You can find out what you need to bear in mind when harvesting them below. Winter lettuces such as endive and radicchio, on the other hand, are harvested whole.

Harvesting Postelein, Rock Lettuce & Picking Lettuce

Small, rosette-forming winter lettuce varieties such as Postelein or lamb's lettuce can be harvested gradually without cutting off the entire rosette. This keeps fresh lettuce in the garden for longer. Only the outer leaves are harvested so that the rosettes can continue to grow. Of course, the entire rosette can also be harvested, but then nothing will grow back.

Picking lettuce can be harvested in a similar way. To do this, only cut off individual leaves of the winter lettuce approx. 4 cm/1,6 in above the ground. This way, the individual plants remain intact and can be harvested again and again.

Harvesting Winter Lettuce: Radicchio, Sugar Loaf & Co.

Lettuces such as radicchio, orchid lettuce, sugar loaf or endive are harvested in one piece. You can either take them out of the ground together with the roots or cut off the lettuce heads approx. 2 cm/0,8 in above the ground. With roots, the heads often stay fresh and storable for longer. To do this, you can either wrap endive and sugar loaf lettuce in newspaper and place them in boxes or embed them in boxes filled with damp sand. The boxes should be kept in a cool and dark (cellar) room. All heads of lettuce will keep for several days in the fridge.
