Sorrel: Features of Cultivation and Care

As practice shows, growing sorrel in the country is one of the simplest tasks that even a gardener who has no experience can handle. To obtain a high-quality, plentiful harvest, these plants are cultivated in closed ground structures; in the absence of such structures, you can cultivate the culture under film shelters or in open beds.

Sorrel is a perennial herb that is cultivated as a two- or three-year-old crop. Sorrel is cultivated for the sake of obtaining super-early greens, rich in iron, oxalic, malic, succinic acids and a number of vitamins and physiologically active substances, including anti-cancer. In old leaves, when flower stalks begin to form, a large amount of oxalic acid is accumulated, which is undesirable for human consumption. Therefore, the main value is represented by young leaves. Those who suffer from diseases of the kidneys, bladder, should refrain from eating sorrel. It is also contraindicated in violation of salt metabolism, intestinal inflammation.

Using sorrel in salads, adding to soup or borsch will only benefit.

Widely used early ripe varieties of selection: Odessa 17 and Broadleaf.

Growing Sorrel in Open and Protected Ground: Planting and Care

This is a cold-resistant plant, withstands frosts to -7 … -8 ° C. therefore, sorrel is widely practiced in open ground, where it winters well and grows early in spring.

The culture is hygrophilous. It grows better on structurally highly fertile, moist, neutral and slightly acidic soils. It does not tolerate wetlands.

Plants are reconciled with shading, so they can be grown in the aisles of the garden. In one place, sorrel gives high yields for 3-4 years.

Sorrel is planted with seeds or rhizomes in open or protected ground. In autumn, the rhizomes of biennial plants are dug up and planted in the greenhouse, end-to-end in rows with 7-8 cm rows. The greenery begins to grow even at a temperature of 7-8 ° C. The optimum temperature for sorrel is 16-18 ° C. After 18-20 days after planting, the first crop is harvested; 3-5 cuts can be made. For one harvest, the crop is 0.5-1 kg per 1 m2.

When caring for sorrel while growing in the country, do not forget that this culture reacts negatively to drying out of the soil, forming a small rosette and a flower arrow. When sorrel is grown in greenhouses, plants are responsive to frequent ventilation of structures.

How to Grow Sorrel in Open Ground and Greenhouse “Carpet” Way

Of interest are the “carpet” method of forcing greenery, sorrel and other green crops, which allows reducing their cost by more than 2 times and labor costs per unit of production by 2-5 times.

Before growing sorrel in open ground by this method, in April – May continuous sowing of seeds is carried out on a thin (5–6 cm) layer of peat spread on root-impermeable material (polyethylene film, concrete, etc.). 500-600 g of lime flour, 60 g of ammonium nitrate, 50 g of double superphosphate, 60 g of potassium sulfate are added per 1 m2 of peat.

During the growing season carry out regular watering and top dressing. In September – October, leaf mass is cut, leaving petioles 4–6 cm long. Then the turf is cut into 40 x 80 cm or 30 x 60 cm layers, large layers are rolled up and brought into storage upon demand or immediately into greenhouses for spreading and forcing greens.

After spreading, the sod is poured at the rate of 10-15 l of water per 1 m2, 20 g of urea are added and again watered (5-10 l of water per 1 m2). Subsequently, regular watering and top dressing are carried out. In the first 10 days after spreading, the air temperature in the greenhouse is 12–16 ° С, and then until the end of the forcing of greens – 18–20 ° С.

Under film shelters, sorrel plants yield 10-15 days earlier than in the open ground. To do this, in the autumn, arched arches are installed over the sorrel bed, and in early March a film is pulled on them. The bed to accelerate the receipt of the crop can be covered with a film of the film without a frame. Its edges are crushed by improvised material. It is better to do this in the second half of March.

When caring for sorrel during cultivation in the open and protected ground, the yield is enhanced by fertilizing with mineral fertilizers in early spring. For 1 m2, 15-20 g of ammonium nitrate, 20 g of superphosphate, 5-10 g of potash fertilizers are needed.
