Radish is one of the first joys for a gardener after a long winter. He is able to quickly relieve the whole family of the lack of natural trace elements and vitamins: group B, vitamin C and PP, calcium, potassium, iron, magnesium, riboflavin, phosphorus, niacin.

Due to the mustard oils, radishes have a pungent taste and are great for raising the appetite. Doesn't it deserve the attention of gardeners in early spring? After all, its growth and development will not stop frosts down to -5 degrees! Moreover, it can be grown in 20-30 days.

In this article, we will analyze in detail how to grow radishes in early spring in a greenhouse in different climatic zones of Russia in order to be one of the first to get a harvest of this useful juicy vegetable.

Features of spring planting radishes

It is in spring, when daylight hours are not yet as long as, for example, in June, that you can get the most enviable harvest. Planted in June, radishes will not be as large and juicy as those planted in March or April. For early planting of radishes, heated and unheated greenhouses are used, as well as greenhouses with biofuel heating.

Nuances for other seasons

In summer, radishes can also be planted... But a long daylight hours will contribute to the formation of arrows, flowering and active development of tops, and not the formation and development of fruits. In this case, it is necessary to cover the radish with a dark cloth (not a film, in order to avoid overheating), limiting the supply of light to the culture to 8-10 hours a day.

For summer planting, it is also necessary to use low-shooting special varieties and hybrids such as White nights, Champion, Virovsky white, Zlata, Children's F1 and others. There are also late-ripening varieties for planting in August. They are not stored and are meant to be consumed quickly.

There is a sub-winter sowing of radish, which is carried out in November. in a garden bed specially prepared from early autumn. However, it is the greenhouse planting of radishes in early spring that provides the most abundant and high-quality early harvest, the fruits of which are perfectly stored in plastic bags in the refrigerator for 3-4 weeks.

When to start sowing seeds?

Radishes can be planted in protected ground as soon as the sun warms up and the temperature is close to zero.

Depending on the climatic zone, in Russia, you can plant radishes in a greenhouse already in February - March.

Of course, in Siberia, where spring begins later than in central Russia, the time for planting radishes in the greenhouse comes in early - mid-April, depending on the time of the arrival of the climatic spring, which in this extended region begins the farther north, the later.

In the Urals, the time for planting radishes in the greenhouse begins in late March - early April. In the middle part of Russia - mid - end of March.

These are the earliest dates for planting to start. However, they have already been tested by professionals and amateurs. Both those and others claim that radish shoots can withstand temperatures up to - 1, and adult plants - up to - 5 degrees.

The difference between the early and late spring periods

For early planting, early maturing and early maturing varieties are used. In this case, large seeds are best suited. Ideally, they should be sifted through a 2.5 mm sieve.

Radish refers to plants in which long daylight hours cause arrowing, flowering of tops. At the same time, the root crop becomes of poor quality. Therefore, for each planting time, including for planting in early and late spring, it is necessary to select the appropriate varieties.

For planting in late spring, which also occurs in different zones in different ways (for example, in the north of the Siberian part of Russia - this is the end of May - beginning of June), the variety Rose-red with a white tip, Half-red - half-white 471, Wurzburg 59, Ledyanaya icicle, Sachs, Novinka, Red giant and similar varieties. Landing is done in open ground.

Growing without heating, in an ordinary greenhouse

It must be said that early cultivation of radish in February - March is possible in a heated greenhouse. Stationary, well-lit and sun-warmed greenhouses are ideal for early planting. But you can grow an excellent early harvest in an ordinary greenhouse, if you organize the so-called "warm" beds with biofeature.

For this, not rotted, fresh manure is laid under the planting. If the manure is dry, it should be soaked in water.... For this purpose, pure horse is suitable, and cow and goat mixed with straw 1: 1. If there is no manure, then ordinary hay, wood shavings, autumn leaves, and, in principle, any dead wood are placed under the beds.

It is tamped with a layer of up to 30 cm, then boiled over with boiling water from a weak solution of potassium permanganate, tightly covered and allowed to steam. Then they are covered with earth for planting. Such arrangement of greenhouse beds will provide an excellent radish harvest at the earliest possible date and without any heating, especially in areas with a later arrival of heat, such as the Northern Urals and Siberia.

Reference! In the European part of Russia, it is quite enough to properly prepare the soil for planting. In case of frost, the soil in the greenhouse is sprayed with water, and the steam formed under the dome of the greenhouse will prevent the plants from freezing.

Step-by-step instructions on how to grow radishes

So, for a good quality radish harvest in early spring, we need to select varieties and prepare the seeds.

Variety selection

It is recommended to plant several varieties of radish at once in order to determine which of them will give the result that suits you. So, early maturing and early maturing varieties that have proven themselves well with early planting:

  • Lightning F1, Dabel F1, Celeste F1, Cherriet F1, Rondar F1, Openwork F1, 18 days - crispy radish without bitterness.
  • Tarzan F1 and Caspar F1 produce bountiful harvests.
  • Rhodes and Riesenbuter (second name - Oil giant) produce large red fruits.
  • More expensive varieties are Masterred, Estarred hybrids.
  • They have proven themselves and are loved by gardeners - Early red, Parat, white marshmallow, Saksa, Alyoshka F1, Chara, French breakfast, Ivolga17 and others.

Buying seeds

Radish seeds can be bought in trusted online stores or company stores seeds throughout Russia. For example, Partner company stores - more than 30 cities in different regions of Russia, AGRO online store - prompt delivery throughout Russia.

Price for 1 gr. seeds ranges from 25 rubles and more, depending on the variety and store.

Sowing preparation

For planting in a greenhouse, the seeds should be sifted through a sieve, selecting the largest ones - from 2 mm. Leave the rest for planting in open ground. Then they are soaked between layers of gauze for 2-3 days, then when the seeds have given tiny bores, they are treated with a weak solution of manganese and soaked according to the instructions in a growth stimulator.

How to plant correctly?

There are several schemes for planting radishes in a greenhouse.:

  • One of them - the grooves are made 5 cm, observing the distance of the seeds in the garden - 4 cm.The planting depth is 1 - 2 cm.
  • There is a way to mark holes by pressing industrial egg cells into the ground. They are also optimally able to organize the landing pattern.
  • Also popular are methods of planting in special cassettes or cups.

Round varieties of radish need a soil layer of 15 cm, and long ones - from 20 cm. The soil for planting should be loose, good moisture permeability. Some gardeners manage excellent yields with a minimum of fertilizer used.

Attention! Radishes do not like acidic soils, so they should be alkalized, for example, with ash.

Care

Caring for young plants is easy enough:

  1. They must be thinned out in time to ensure a distance of at least 4-5 cm, loosened and watered 1-2 times a day.
  2. The temperature required to support the growth of young plants ranges from 10 to 20 degrees Celsius.

    The first days after the sprouts hatch, it is better to provide 6-8 degrees of heat to avoid pulling the seedlings. After 4 days of growth, the temperature becomes optimal from 12 to 18 degrees. At night, the temperature in the greenhouse can drop to 10 degrees. However, the plants will not die even in case of frosts down to -5 degrees.

  3. Young plants should be fed twice for growth with nitrogen fertilizers (20 g per 1 m²). Sprinkle humus on top of the beds will keep them from drying out and will also provide the necessary top dressing. For more details on how to feed the plant after germination in the greenhouse and in the open field, read here.

Harvesting and storage of crops

When the fruits are over 2 cm in diameter, you can start harvesting... It is done in three steps, collecting the largest ones. Store early radishes in a cool, dark place in ajar plastic bags.

What difficulties can there be?

All the difficulties associated with maintaining the optimal temperature in the greenhouse are easily overcome by the root crop itself, which is extremely unpretentious and ready to please the gardener with an excellent harvest at any time of the year.

The main thing for the successful cultivation of radishes is a loose prepared soil and adherence to the length of daylight hours. The latter is easily observed in the case of early spring planting in a greenhouse. Taste, grow and get a vitamin boost from early spring to late autumn!
