Spinach is a rich source of iron. It is part of hemoglobin, which supplies oxygen to all cells in the body. Especially recommended for women, children and teenagers.

Garden spinach (Spinacia oleracea) - a species of the genus Spinach of the Amaranth family (Amaranthaceae); in the older classification - Haze. The culture is grown almost everywhere. But if there are any secrets of spinach care, you will find out by reading this article.

Debunking spinach myths

Spinach is an annual herbaceous dioecious vegetable plant 30-45 cm high with alternate triangular-spear-shaped leaves. Stamen flowers are green, small, collected in spike-paniculate inflorescences. Pistillate flowers are collected in glomeruli located in the leaf axils. Fruits are oval nuts, collected in glomeruli with lignified bracts. Blooms in June-August.

At the beginning of the 20th century, spinach was extremely popular in Western countries. At that time, it was mistakenly believed that spinach was the richest food in iron (35 mg of iron per 100 g of vegetable). Doctors especially recommended spinach to children. In fact, the iron content in spinach is 10 times less. The confusion arose from a researcher who forgot to put a decimal point in the number. The refutation of this myth appeared only in 1981.

According to another version, the error arose in 1890 as a result of the study of dry spinach by the Swiss professor Gustav von Bunge. Von Bunge's results (35 mg iron per 100 g of product) were correct, but he did not investigate fresh, but dried spinach. Fresh spinach is 90% water, meaning it contains not about 35, but about 3.5 mg of iron.

Sowing spinach

Spinach is an early ripening vegetable, therefore, as a quick-acting fertilizer, well-decomposed manure or humus is introduced under its crops. It is especially necessary to introduce humus with an early culture and thickened crops.

Soil preparation

Spinach is picky about soil fertility, so it is placed in a cultivated area rich in organic substances. It gives the highest yields on loamy soils; on sandy ones, in order to get high yields with good quality greens, it is necessary to water the spinach frequently. Soil with high acidity must be limed beforehand. The best precursors for spinach are vegetables that have been organic fertilized.

The soil for spinach is prepared in the fall: the site is dug to the full depth of the humus layer and mineral fertilizers are applied (30 g of superphosphate, 15 g of potassium chloride per 1 m2). At the same time, if necessary, liming of the soil is carried out. In early spring, as soon as the soil is ripe for processing, urea is applied under the rake in an amount of 20 g per 1 m2.

Fresh organic fertilizers (manure, slurry, etc.) are not recommended to be applied directly under the spinach crop, as they negatively affect the taste of the leaves.

For sowing spinach, as a rule, special plots are not allocated; more often it is sown in the spring as a predecessor of heat-loving late vegetable crops. In small areas, spinach is sown as a compactor (among other vegetables or in the aisles of the garden).

Sowing spinach in greenhouses

In springtime, in greenhouses, spinach is grown mainly in greenhouses and on insulated ground. Under these conditions, good results can only be obtained on soils with a lot of humus. Usually, a mixture of humus and sod or garden soil (in equal amounts) is prepared for greenhouses.

Spinach is photophilous, therefore, spring crops in greenhouses begin in the Moscow region only from the end of February. Sowing is carried out with a greenhouse seeder, the distance between rows is 6 cm. For 1 sq. m sow 20-30 g of seeds. When grown in greenhouses, the temperature is maintained at 10-12 ° C - in cloudy and 18 ° C - in sunny weather.

Previously, spinach seeds should be soaked in water for one to one and a half days in order to get earlier and more friendly shoots. Immediately before sowing, the swollen seeds are slightly dried so that they do not stick together.

Sowing in open ground

Spinach is a fairly cold-resistant plant and grows well outdoors. Spinach seedlings are able to withstand frosts down to –8 ° С. Spinach planted before winter can hibernate under the snow (in the middle lane with a little cover).

Sowing spinach in open ground is possible when the snow has completely melted - from mid-April to July - for using mature leaves, until mid-August - for using young ones. Conveyor sowing is done at intervals of 20-30 days.

In summer, sowing spinach can only be carried out in areas previously moistened with watering. Before emergence, the plots are covered with old matting and other materials to speed up the emergence of seedlings.

On ridges, spinach is sown in an ordinary way with row spacing of 30 cm, the seeding depth is 2–3 cm, the seeding rate is 4–5 g per 1 m2. After sowing, the soil is rolled up.

For autumn consumption, spinach is sown in June-July, and in the southern regions - in August, as a winter crop, which allows it to be harvested in early spring. In places where the winter temperature does not drop below 12 ° C, spinach grown in autumn can be harvested during the winter.

Spinach care

When the seedlings grow up (a second true leaf appears), the crops are thinned out, leaving the plants at a distance of 8–10 cm from each other, since two seedlings appear from one ball-seed in spinach. Thickening of crops is undesirable - with poor aeration, the risk of infection with powdery mildew increases. The distance in the row between the plants should be about 15 cm. It is very important to be careful not to damage the remaining plants. After thinning is complete, the spinach is watered.

To prevent premature stalking of plants in dry and hot weather, spinach should be watered abundantly. If the need arises, watering is combined with fertilizing with nitrogen fertilizers (10-15 g of urea per 1 m2). It is not recommended to feed spinach with phosphorus and potassium fertilizers, as they accelerate the shooting of plants.

Throughout the growing season, the soil must be loosened regularly. In dry weather, plants need watering to form a good harvest and a decent look. Usually it is enough 2-3 times a week, 3 liters of water per running meter of a row. Normal soil moisture avoids spinach stalking.

Harvesting

The spinach harvest begins when the plants have 5–6 leaves. Spring-sown spinach is ready for harvesting 3-5 weeks after germination, summer spinach in 4-6. It is very important to harvest on time: if the plants grow old, the leaves will become coarse and tasteless.

The rosettes are cut under the first sheet or plucked out by the roots. But you can pluck the leaves just as needed. It is better to harvest spinach in the morning, but not immediately after watering or rain, since at this time the leaves are very fragile and break easily.

The spinach yield is 1.5–2 kg per m2.

They can also be transported and stored only in dry form. Store spinach on the bottom shelf of the refrigerator in a plastic bag for no more than two days. For preparation for the winter, it can be frozen - in frozen form, it retains its useful properties well.

Diseases and pests of spinach

Aphids willingly settle on juicy spinach leaves, and larvae of mining flies also eat them. Naked slugs and snails love this vegetable too. Downy mildew may appear on the leaves in late summer, especially if the plantings are dense. Plants are often affected by various spots.

It is quite difficult to fight these pests and diseases, since leafy vegetables are not recommended to be sprayed with pesticides. Therefore, for prevention, it is important to strictly adhere to agricultural techniques and remove plant residues in a timely manner. To avoid powdery mildew, it is better to choose varieties resistant to it ('Spokane' F1, 'Sporter' F1).

Spinach seedlings and young plants can be attacked by root rot. The root collar rots, the plant withers and then dies. Control measures - thinning, loosening. You cannot place crops after beets.

Spinach is damaged by larvae of beet-miner flies and aphids. Seed crops are sprayed with anabazine sulfate at the rate of 15 cm3 per 10 liters of water or phosphamide (0.2%). Food crops should not be sprayed.

Benefits of spinach

Spinach leaves contain proteins, fats, sugars, fiber, organic acids, flavonoids, along with this, a balanced multivitamin complex - vitamins of groups B, C, P, PP, E, K, is rich in vitamin A (carotenoid), as well as many essential man with minerals - iron, potassium, magnesium.

Spinach is used to prevent gastrointestinal diseases; with anemia, anemia, exhaustion, diabetes mellitus, hypertension; give small children in the form of puree to prevent rickets. Also, spinach prevents retinal degeneration, has a mild laxative effect, and stimulates the intestines. Recommended for pregnant women because contains a high amount of folic acid. The high content of vitamin E protects the cells of the body from aging.
