Red Salad Bowl Lettuce

Saqueta Individual

€1,50

A strikingly beautiful oak leaf lettuce with long, deeply cut dark-red leaves that fill the bed with colour.

About the variety. This is a slow-bolting variety — it resists bolting and remains productive for longer. Its compact habit of around 20 cm also makes it well suited to containers.

Como cultivar red salad bowl lettuce?

Um guia de cultivo passo a passo, da sementeira à colheita.

pH ideal 5.5 and 7Temperatura ideal 20 and 30°C

Sementeira

Sown in trays, seedlings should be transplanted to their final location 3 to 4 weeks later. The crop can be grown in rows, with 15 to 20 cm between plants and 45 to 60 cm between rows.

Solo

It is a crop that adapts well to different soil types, though good drainage capacity is essential. Soil pH should be between 5.5 and 7.

Clima

The crop prefers temperatures between 20 and 30°C; however, temperatures should not be extreme, as they will cause premature bolting.

Fertilização

Compost should be incorporated into the base fertilization to meet the crop's needs. It is important that the soil has phosphorus at the beginning of its development; if it is not present at a sufficient level in the soil even after incorporating compost, a mineral fertilizer rich in that nutrient should be added.

Rega

Watering should be done regularly, as the root system is not very deep. Drip irrigation is ideal for lettuce cultivation, as it prevents excessive moisture on the leaves and thus the onset of disease.

Controlo de Infestantes

Mulching is an interesting option for lettuce cultivation, reducing competition between weeds and the crop.

Controlo de Pragas

Mites, aphids, leaf miner larvae and root-knot nematodes are pests of this crop. Mite control can be achieved through biological control with predatory mites, with azadirachtin or sulphur dust applicable if necessary (when T < 28°C). Aphids can be controlled through moderate fertilisation without excess nitrogen, natural limitation with border hedgerows to support beneficial insects, biological control with parasitoid and predatory Hymenoptera, and the application of potassium soap or azadirachtin if needed. Leaf miner larvae can be controlled through natural limitation with hedgerows and other vegetation including nectar-rich plants that feed parasitoid adults, biological control with parasitoid Hymenoptera, and, as a complementary measure, the application of azadirachtin. Root-knot nematodes are controlled through crop rotation, biofumigation and soil solarisation.

Doenças

Alternaria blight, Sclerotinia, downy mildew and grey mould are diseases that affect this crop. To control Alternaria blight, wide plant spacing and copper-based fungicides (such as Bordeaux mixture) should be used. To control Sclerotinia, appropriate crop rotations and wider spacing should be practised, and infected plants should be removed from the field as early as possible. Downy mildew can be controlled through crop rotations of at least 3 years, avoiding excess soil moisture and air humidity, using wide spacing and, if necessary, applying copper hydroxide at reduced concentrations (which should be lower the colder the weather, as it may risk scorching the leaves). Finally, grey mould should be controlled by removing diseased plant debris, avoiding excessive vigour, keeping water off the plants and applying bentonite clay on a regular basis.
