Planting lettuce

Planting lettuce

Lettuce should be planted in well-lit beds in loosened, fertile, non-acidic soil. Lettuce requires a lot of potassium and nitrogen.

You can grow zucchini before the salad in the garden, cucumbers, cabbage and other plants that require a high content of organic fertilizers.

The salad area needs to be prepared in the fall.

If the soil was not fertilized, then when digging into it you need to add 1 sq. meter half a bucket of compost, 1 tablespoon of superphosphate, 1 tablespoon of potash fertilizers... If the soil is acidic, add ash. In the spring, to retain moisture in the soil, it must be loosened. Five to six days before sowing, loosen the soil again to a depth of about 12 centimeters, add ammonium nitrate (1 teaspoon per 1 square meter), level the beds, crushing large lumps.

In greenhouses, lettuce is best grown between or along the edges of the beds occupied by tomatoes or cucumbers... It is recommended to plant lettuce in the greenhouse two to three days before planting the main plants.

Lettuce is propagated in open beds seeds, occasionally - seedlings... Sowing lettuce can be started from April to the end of August, with an interval of fifteen days. In summer, it is recommended to sow late-ripening varieties that are resistant to the formation of flowering stems.

For planting, make furrows about 1.5 cm deep and about 15 cm apart.

The gap between seeds (by plants) must be at least 5 centimeters long. When the salad is cramped, the leaves become coarse. For better growth, you can add granular superphosphate (0.5 per 1 m2) when planting. Roll up the soil to speed up germination. Leaf lettuce can be sown between rows cabbage: it protects it well from the sun, and by the time the cabbage gets stronger, the salad can already be harvested.

Growing lettuce

Growing lettuce

Leaf lettuce does not require much maintenance - you need to regularly loosen the soil and clean weeds... Thin seedlings to form a good rosette.

The salad loves moist soil, but suffers from fungal diseases from excessive moisture, quality harvest while decreasing. Water a lot, but not very often, to avoid over-wetting the soil. At the same time, do not dry out.

The salad is very resistant to cold weather, it is not afraid of frosts down to minus 3 degrees.

If sockets (heads of cabbage) have managed to form - even up to minus 6 degrees. Autumn varieties can withstand the cold of minus 10 degrees. Lettuce varieties with pigmented leaves are most resistant to low temperatures. If the plant grows poorly, when two or three leaves appear, it must be fed with ammonium nitrate (0.5 tsp per 1 sq. M). It is important to remember that lettuce absorbs nitrates, so do not use fertilizer unless necessary.

Temperature range:

  • For shoots, lettuce has enough temperature plus 2 degrees, for full development + 5 ° C.
  • The best growth is achieved at plus 16-18 ° C during the day and 12-13 ° C at night.

Leaf lettuce tolerates a lack of moisture and heat worst of all. The leaves are small, rough, bitter. In hot climates, lettuce throws out arrows and leaves no leaves. Lettuce grows well under long, good lighting, especially for early ripening varieties. When the daylight hours are reduced, the formation of arrows slows down. The salad should not be planted thickly, as it stops developing.

Harvest

Harvest

It is recommended to remove the salad after the appearance of six eight leaves, as later they coarse and become tasteless.

Collection harvest should be carried out in dry weather in the morning or evening.
