Spinach is a culture rich in trace elements and vitamins such as iron, phosphorus, B vitamins and other beneficial substances that will help maintain beauty and health for many years.

Not everyone undertakes to grow it, thinking that the plant requires special attention to itself. But this is not so, because sowing and caring for spinach is quite simple if you know all the basic nuances. This article will tell you what kind of care spinach requires, how to grow it at home and outdoors, and what diseases and pests can threaten spinach.

How to properly care for outdoors in the garden, dacha: agricultural technology, features and conditions

The spinach growing technology is quite simple. You just need to take into account some features so that the crop can be harvested for more than one season (how to properly harvest spinach?).

Temperature

Since spinach is a cold hardy plant, it can withstand temperatures as low as –8 degrees. It can be sown in winter to harvest in spring. Seeds germinate at a temperature of 2-5 degrees Celsius. It is recommended to sow when the soil warms up to 10 degrees.

The optimum temperature is considered to be 15 degrees., as at a higher air temperature, the plant can shoot an arrow and become unfit for human consumption. The maximum temperature is 20-35 degrees, depending on the variety. For more information on when to plant early, mid-season and late spinach varieties, we wrote here.

Watering and moisture

Although the plant is moisture-loving, it does not like stagnant water. Spinach has a small root system, but you need to water abundantly, at least three liters per square meter. In dry and hot weather, watering is done every day to avoid premature stemming. This will produce the perfect crop.

Shine

Spinach is not afraid of direct sunlight, it also grows well in the shade. But to form a powerful rosette with high nutritious leaves, you need to plant the plant in a well-lit, sunny place. You should also avoid areas where cold winds are blowing.

Important! When the air temperature reaches 25 degrees Celsius, the spinach needs to be shaded so that the leaves do not become tough and tasteless.

Priming

Although spinach is not picky about the soil, it is better to grow the plant in cultivated and fertile soil enriched with organic matter. Loamy and sandy loam soils will provide a rich harvest. If the soil is highly acidic, you need to add limestone to equalize the acidity, otherwise sowing will not bring results. Dolomite flour or organic matter can be added.

How to feed?

Prepare spinach soil in advance: in the fall, mineral fertilizers (potash and phosphate) are applied to the dug area. At this time, liming of the soil is also carried out. At the beginning of spring, urea is introduced to cultivate the land under a rake. Before sowing itself, you need to fertilize the soil with manure or humus. After germination, it is better not to fertilize with anything.

Is it possible to transplant and how?

After the first thinning, the torn shoots can be transplanted to another bed. So that the small roots can firmly adhere to the ground again, they need to be well watered.

How to feed after germination?

You can not apply mineral fertilizers as top dressing, because this will affect the acceleration of stemming. If spinach does not grow well, you need to feed the plant with urea along with water.

It is not recommended to use organic fertilizers after germination., as this will affect the taste of spinach, and a large dosage can even burn the roots of the plant.

Thinning

After two or three leaves appear on the outlet, the seedlings are thinned out. After this procedure, the distance between the shoots should be 10-15 cm. At the end, the beds should be abundantly watered.

How to care if planted in a greenhouse: main features

To harvest nutritious spinach all year round, you can grow it in a greenhouse. In severe frosts, it will be necessary to heat closed areas with plants with candles or other devices, and it is also desirable to set up artificial lighting.

Sowing a crop and further care is almost the same as growing outdoors. The first time the seeds are planted in the fall, then in January.... After the appearance of several leaves on the outlet, the beds need to be thinned out, and the soil must be loosened.

Water the spinach in cold weather once a week. Soil moisture should be 80%. This is a prerequisite for growing and getting a good harvest. Two weeks after watering and cutting the crop, fertilizing is done.

Important! The greenhouse must be periodically opened for ventilation to avoid the multiplication of fungal diseases. At a temperature of 12 degrees Celsius, you can remove the film for a day.

Are there any differences when grown at home?

As such, there are no differences in growing spinach at home.... You need to sow spinach in pots with fertile soil, as well as with expanded clay drainage at the bottom. The seeds must be soaked in advance, and then put into the deepening. After it is sprayed with water and covered with a film until the first shoots appear. The pots should be placed on the windowsills, watered periodically to prevent the soil from drying out, and fertilized once every two weeks.

We suggest you watch a video about growing spinach at home:

Sowing seeds and planting

  1. Before planting, the seeds must be soaked for two days in water, which must be changed several times during this time. After they need to be dried to their previous state.
  2. Having made grooves in the moistened soil, seeds are placed there to a depth of 2 cm and at a distance of 15-20 cm from each other.
  3. After sowing, the ground is leveled with a rake.
  4. For growing from seedlings, the soaked seeds are planted one by one in the cells of special cassettes.
  5. The ground is moistened with a spray bottle and covered with foil.
  6. After the grown plant is transplanted into a larger pot, and then, after hardening, into open ground.

Diseases and pests

Often, due to improper care, abundant and frequent watering, as well as weeds in the neighborhood, a disease or a harmful inhabitant can appear on spinach. To avoid and prevent this, you need to find out the reasons for their occurrence. If, nevertheless, the plant has a "disease", you need to know how to deal with it.

  • Anthracnose... Plant disease caused by parasitic fungi. Appears as small brown or gray spots on the leaves with a dry center and a bright yellow or purple border. This disease is easier to prevent than to cure, so you need to properly care for the crop. High air temperature and humidity, mechanical damage from insects, insufficient soil fertilization - all this contributes to the appearance of anthracnose.
  • Rot... The causative agents of the disease are fungi. It affects young shoots at the time of stem formation. Diseased spinach has darker leaves and is noticeably stunted. After defeat, it fades, dries up and dies. The reason for the appearance of rot is the high air temperature (from 16 to 40 degrees). To avoid this, you need to properly prepare the soil before planting, loosen and remove weeds from the beds in time, and also remove the affected plants.
  • Viral diseases... The cucumber mosaic virus is considered very dangerous when the leaves are deformed. They become curly with light green spots, stunted. It occurs by infection from perennial weeds due to aphids and leafhoppers. To prevent the appearance of the disease, you need to get rid of weeds, as well as pollinate the plants with tobacco dust or ground tobacco waste.
  • Spotting... It manifests itself on the ground parts of the crop, which affects the quality of the product. It occurs due to high humidity and stagnant water in the beds. It is necessary to destroy damaged plants, loosen the soil and fertilize.
  • Medvedka ordinary... Eats up almost all spinach roots, thereby destroying the culture. To get rid of it, you need to loosen the ground between the rows well to destroy the eggs and the bear itself. To prevent this pest, it is recommended to put manure on a shovel in shallow holes in the spring. In winter, the bear will settle in these pits, where it will be easier to destroy them.
  • Miner fly... She lays eggs in the leaves of the culture, from which the larvae emerge. They eat all the leaves, from which the plant dies. To avoid the appearance of this pest, you need to plant spinach next to the beetroot rows.
  • Caterpillar scoop-gamma... It can be green or brown. Relocated to spinach from weeds. To avoid the harmful influence of this caterpillar, you need to get rid of weeds by removing them away, and also spray the spinach with an infusion of tobacco, pepper or tomatoes.
  • Beet fly... She lays her eggs in spinach leaves. You can get rid of it by spraying anabazine with sulfate or phosphamide solution.
  • Babanukha... It is a black beetle with green overflow and brown legs. You can get rid of by sprinkling with a mixture of wood ash, mustard powder and red pepper. You also need to pull out all the weeds and loosen the soil.

Spinach does not require special care, is not whimsical during planting and proximity to other crops, and also does not take up much space in the beds. It is very easy to grow it and if you follow all the recommendations, then a useful culture can be on the table all year round.
