Garden radish is one of the first joys for a gardener after a long winter. He is able to quickly save the whole family from the lack of natural trace elements and vitamins: group B, vitamin C and PP, calcium, potassium, iron, magnesium, riboflavin, phosphorus, nicotinic acid.
Because of mustard oils, radish has a sharp taste and perfectly lifts the appetite. Does he not deserve the attention of gardeners already in early spring? After all, its growth and development will not stop frosts to - 5 degrees! In this case, it can grow in 20-30 days.
In the article we will discuss in detail how to grow radishes in early spring in a greenhouse in different climatic zones of Russia, in order to be among the first to get a harvest of this useful juicy vegetable.
Features of spring planting radishes
It is in the spring, when the light day is not as long as, for example, in June, you can get the most enviable harvest. Planted in June, the radish will not be so large and juicy as planted in March or April. For early planting of radish, heated and unheated greenhouses are used, as well as biogreating greenhouses.
Nuances for other seasons
Radish can also be planted in summer. But a long light day will contribute to the formation of arrows, flowering and the 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 flow of light to the crop to 8-10 hours a day.
For summer planting, it is also necessary to use special types and hybrids, such as the White Nights, the Champion, the White Virovsky, Zlata, Children's F1 and others, that are weakly shooting. There are late-ripening varieties for planting in August. They are not stored and intended for quick consumption.
There is a subwinter seeding radish, which is carried out in November in a bed specially prepared from early autumn. However, it is the greenhouse planting of radish in early spring that provides the most abundant and high-quality early harvest, the fruits of which are beautifully stored in plastic bags in the refrigerator for 3-4 weeks.
When to start sowing seeds?
Radish can be planted in a protected ground as soon as the sun warms and the temperature is close to zero.
Depending on the climate zone, in Russia you can plant radishes in a greenhouse as early as February - March.
Of course, in Siberia, where spring begins later than in the middle part of Russia, the time of planting a radish in a greenhouse comes in early - mid-April, depending on the arrival time of the climatic spring, which in this extended region begins the north, the later.
In the Urals, the time of radish planting in the greenhouse begins in late March - early April. In the middle part of Russia - the middle - the end of March.
This is the earliest start of landing. However, they have already been tested by experts and amateurs. Both those and others argue that Radish shoots withstand temperatures up to - 1, and adult plants - up to - 5 degrees.
The difference between the early and late spring period
Early planting and early ripening varieties are used for early planting. In this case, the seeds are best suited large. Ideally, they should be selected by sieving through a 2.5 mm sieve.
Radish refers to plants in which a long daylight day causes rifling, flowering tops. The root crop at the same time becomes poor-quality. Therefore, for each time of planting, including for planting in early and late spring, it is necessary to choose 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 is Pink-red with a white tip, Semi-red - semi-white 471, Würzburg 59, Icy icicle, Sachs, New, Red giant and similar varieties. Planting is done in open ground..
Growing without heating, in a normal greenhouse
I must say that the early cultivation of radish in February - March, possibly a heated greenhouse. Stationary, well-lit and sun-warmed greenhouses - ideal for early planting. But to grow a great early harvest can be in an ordinary greenhouse, if you organize the so-called "warm" beds with biogue.
To do this, under planting lay not rotten, fresh manure. If the manure is dried up, it should be soaked in water.. For this purpose, suitable horse in pure form, 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 down with a layer of up to 30 cm, then boiled over from a weak solution of potassium permanganate, tightly covered and allowed to steam. Then covered with earth for planting. Such arrangement of greenhouse beds will provide an excellent yield of radish in the earliest terms 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 ground for planting. In case of frosts, the soil in the greenhouse is sprinkled with water, and the steam formed under the greenhouse will not allow the plants to freeze.
Step by step instructions on how to grow radishes
So, for a good quality harvest of radish in early spring, we need to choose varieties and prepare seeds.
Variety selection
It is recommended to plant several varieties of radish at once in order to decide which of them will give the result that is suitable for you. So, early maturing and early ripening varieties that have worked well for early planting:
- Lightning F1, Dabel F1, Celeste F1, Cherryriet F1, Rondar F1, Openwork F1, 18 days - crisp radish without bitterness.
- Tarzan F1 and Caspar F1 produce abundant harvests.
- Rhodes and Riesenbuter (second name - Oily Giant) give large red fruits.
- More expensive varieties - hybrids Masterred, Estarred.
- Excellent established and loved by gardeners - Early red, Parath, white marshmallow, Sachs, Aleshka F1, Chara, French breakfast, Ivolga17 and others.
Buying seeds
Radish seeds can be bought in proven online stores or retail stores seeds throughout Russia. For example, the partner company’s shops are more than 30 cities in different regions of Russia, the AGRO online store is a prompt delivery throughout Russia.
Price for 1 gr. seed ranges from 25 rubles and up, depending on the variety and store.
Preparing for sowing
For planting in the greenhouse, the seeds should be sifted through a sieve, selecting the largest - from 2 mm. The rest leave for planting in open ground. Then they are soaked between layers of gauze for 2-3 days, then when the seeds are given tiny boring, they are treated with a weak solution of manganese and soaked according to the instructions in the growth stimulator.
How to plant?
There are several schemes for planting radish in a greenhouse.:
- One of them - the grooves make 5 cm, keeping the distance of seeds in the garden - 4 cm. At the same time, the planting depth is 1 - 2 cm.
- There is a way to mark holes by indenting industrial egg cells into the ground. They are also optimally capable of organizing a landing pattern.
- Also popular methods of landing in special cassettes or cups.
Round varieties of radish need a layer of soil from 15 cm, and long - from 20 cm. The soil for planting should be loose, well permeable to moisture. Some gardeners manage excellent yields with a minimum of fertilizer used.

Care
Care for young plants is quite simple.:
- They need to be thinned out in time to ensure a distance of at least 4-5 cm, loosen and water 1-2 times a day.
- The temperature required to maintain the growth of young plants ranges from 10 to 20 degrees Celsius.
The first days after the sprouts have proklikulis, it is better to provide 6-8 degrees of heat to avoid pulling shoots. After 4 days of growth, the temperature from 12 to 18 degrees becomes optimal. At night, the temperature in the greenhouse can drop to 10 degrees. However, the plants will not die in the case of frost down to -5 degrees.
- Feed young plants should be fed twice with nitrogen fertilizers (20 g per 1 m²). Humus sprinkled on top of the beds will prevent them from drying out and also provide the necessary additional feeding.
Harvesting and storage of the crop
When the fruits are poured from 2 cm in diameter, you can start cleaning. It is done in three steps, collecting the largest. Store early radish in a cool dark place in half-opened plastic bags.

What could be the difficulty?
All the difficulties associated with maintaining the optimum temperature in the greenhouse are easily overcome by the root 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 radish is a loose, prepared soil and respect for the length of daylight. The latter is easily observed in the case of early spring planting in the greenhouse. Try, grow and get a vitamin charge from early spring to late autumn!
