The Lettuce

Lactuca sativa

Cultivation

It is easy to cultivate it, but we know many types of it. We can sow it on a permanent place (already with two up to 3 ° C), or we can prepare the shoots with or without ground bread of the root. During germination, it does not like high temperatures, so we must provide shade. We always sow in a row. Distances must be adapted to the individual species of lettuce. It already manages above 5 ° C, the optimal temperatures for growth and development turn around 18 ° C.

Distances

They depend on a single variety. For spring and autumn varieties with fragile leaves at least 40 cm between the rows and 30 cm in a row, with leaves also keep 5 cm less. For summer cultivation, the distances can be 10 cm less.

Position

With sunny skies.

Quantity

Five plants per person.

Date of sowing

Outdoors March-September, according to the instructions for the single variety. In autumn, we increase the possibility of a successful wintering with two sowings. Sprouts from 7 to 10 days.

Composting

It does not need special fertilization, only light earth.

Watering

The earth must always be moist. Let’s start with watering if the top 5 cm is dry. We water in the morning, in the evening only with heated water.

Good neighbors

tomato, pepper, sweet corn, chard, zucchini, cauliflower, onion, black horseradish, comfrey, chives, beans, peas, cucumbers, kohlrabi, cabbage, parsnip, leek, turnip, radish, celery, cabbage, mint, spinach, fennel, carrot, strawberries

Bad neighbors

parsley

Diseases and pests

It grows quickly, so if the distance between the plants is adequate and the fertilization is moderate, it has fewer pests. It is the lice of the roots of the larvae of elaterids and of the late blight of lettuce.

Collection

We cut it down, if possible, and in the afternoon when it contains fewer nitrates. To clean it, we do not use metal knives, since the chemical reaction to contact decreases the number of vitamins. In the fridge, we keep the lettuce not clean and dry. We clean the whole leaves.

Supply

Fresh leaves. It contains many vitamins, minerals, and fibers. The quantities are greater in lactoses with dark leaves and less fertilized, smaller instead in plants coming from greenhouses, blond lettuce with curly leaves, and large parts in head varieties.

Important

We ensure that the earth becomes light. We accelerate the sprouting with yarrow tea. We use fresh seeds, as new as possible. Its development depends on the length of the day. We prevent the going to flower with the right choice of variety depending on the season.

Special features

For sowing in early spring, varieties with fragile leaves are more suitable, such as the Brazilian, the bistro, the polka, the Ljubljana iceberg, the varieties with fragile leaves for the summer heat, the leda, the Ljubljana iceberg, the unicum, brown American lettuce, the Dalmatian iceberg. The varieties that winter: vegorka, polka, and bistro (with fragile leaves), brown in winter, and Nansen (with soft leaves). Soft-leaved varieties for use in early spring and late autumn are an attraction and queens of May.
