How to get an early harvest of radishes in an unheated greenhouse, an overview of varieties. When to plant radishes in a greenhouse for an early, bountiful harvest

Crispy, juicy and tasty radishes are always a welcome guest: they are adored by both adults and children who eat the vegetable just like that or in fresh salads.

It can be obtained even on the windowsill, but more often it is practiced to grow radishes in a greenhouse and open ground, where more vitamin fruits are harvested. Learn how to grow radish root crops in greenhouse conditions using greenhouses made of glass and more modern and popular polycarbonate.

Terms of planting radishes in the greenhouse

This vegetable crop is characterized by unpretentiousness and frost resistance, and therefore is sown in greenhouses in early March. Unlike sowing radishes in open ground, seeds hatch faster in greenhouse conditions.

To get early spring harvest seeds are sown from March 1 to May 15, choosing early-ripening varieties that ripen in 16-25 days. Such a radish is not stored for a long time.

Seeds of vegetables of medium and late varieties intended for more long-term storage, sow in early July - early September. Of course, it is possible to grow radishes in winter, if the greenhouse is heated and well lit, because. vegetables need 10-11 hour daylight hours.

It is impossible to plant radishes in a polycarbonate or glass greenhouse in the second half of May - June: due to the long daylight hours, it will grow a lot of greenery and release flower stalks, and root crops will not develop. True, you can shade the greenhouse, providing lighting for no longer than 11 hours.

Preparation of radish seeds

Before growing radishes in a greenhouse, we select high-quality achenes using the following technology:

• Sorting. Having scattered the seed material on paper, we reject too small, grayish and shrunken seeds: to grow a good radish in a greenhouse, only healthy seeds of medium and large size are needed.
• We disinfect. To prevent the development of diseases, before planting radishes in a greenhouse, we process the seed with potassium permanganate, making a light pink solution and holding the seed in it for 20 minutes.
• Soaking. To activate the growth processes and rapid germination, keep the radish seeds in a solution of any growth stimulator for 4 hours, placing them in gauze.

Having finished preparation, we wash them with running water, dry them on cotton or linen fabric and start landing.

Soil preparation for planting radishes in a polycarbonate or glass greenhouse

We prepare greenhouse ridges for growing radishes in the fall, performing the following manipulations:

• We take out the tops of harvested plants from the greenhouse in order to protect the future crop from pests and diseases.
• We dig up the soil, adding, if necessary, a bucket of humus per square meter.
• "We make it easy" clay soils peat: they will become looser and more fertile.

In the spring, shortly before planting, we thoroughly loosen the dug-up earth and level the surface. If it is still cold, we thoroughly spill the ridges before sowing the radish. hot water, cover with a film or agrofiber and wait for three days.

Sowing radishes in a greenhouse

Like sowing radishes in open ground, planting seeds in greenhouses can be early or later:

• Sowing in early spring . We fill the beds with a layer of snow 5-7 cm thick and scatter seeds on top of it. As the snow melts, they will be drawn into the soil. The method is convenient in that you do not have to make grooves and immediately water the plantings.
• Sowing after warming. warm spring and in the summer we make grooves in the beds 1 cm deep and 10 cm apart, water and sow the seeds every 5 cm.

If the crops turned out to be thick with the cold method, after the appearance of the first leaves we thin them out, otherwise they will take away food, light and water from each other. Thick radishes will not give a good harvest.

How to grow radishes in a greenhouse, growth regime and care

When growing radishes in a greenhouse, it is important to observe the irrigation regime, optimal temperature and lighting, otherwise you will not be able to get the desired result.

• Lighting. Radish is enough for 11 hour daylight hours: if it is, additional lighting not required. If it is light in the greenhouse for more than 12 hours, we will certainly shade the beds, otherwise the plantings will go to the arrow. You can cover the ridges with a dark film or a black non-woven covering material.

If there is not enough light, the radish actively grows greens, and not root crops. To avoid excessive formation of tops, we highlight vegetables with fitolamps or other lamps.

• Temperature. Despite the cold resistance of the culture, a temperature of + 16-19 degrees is required for the formation of fruits. When the first leaves begin to form, we provide for three days temperature regime+ 8-10 ° C, then the plant needs heat.

• Watering. Moisture-loving radish needs regular watering and loosening so that a crust does not form on the ground, and the roots can absorb moisture and breathe. Water the plants every day hot weather- twice a day - in the morning and in the evening.

If it is necessary to lower the temperature in the greenhouse, we water the ridges completely - both vegetables and aisles.

Now it is clear what the cultivation of radish in a greenhouse made of glass and polycarbonate is, what conditions this vegetable needs to form high-quality root crops. Before harvesting, we water the ridges abundantly and selectively harvest the fruits in two to three stages, since they ripen unevenly. We collect radishes on time: overripe fruits are flabby, dry, bitter and coarse.

In terms of its useful and taste qualities, radishes grown in a greenhouse are not inferior to vegetables from open ground. Cold-resistant culture allows you to get the first harvest of useful products in the earliest spring.

Radishes belong to the Cruciferous family and grow in annual and biennial crops. European varieties of vegetables are suitable for growing indoors, forming small root crops weighing 10-20 g. Radishes can have a round or elongated shape and different ripening periods. For planting in a greenhouse in which heating is not arranged, choose an early variety intended for growing in protected ground. Radish varieties for greenhouses and greenhouses are more resistant to stemming and shading.

Growing conditions

Radishes are not whimsical and one of the most precocious crops. In order to learn how to plant a radish in a greenhouse and grow it safely in the Moscow region, Leningrad region or in the Urals, you should know the features of the agricultural technology of this crop.

Cold-resistant radishes can germinate at +3°C. In greenhouse conditions, it is able to withstand a temporary drop in temperature to -1 ° C. But to start development, it needs a daily temperature of + 10 + 12 ° С, and for the formation of root crops - + 18 ° С. With more low temperatures the radish will develop more slowly.

Radish appearance

Culture is demanding on lighting. In greenhouses, when sown early, especially with prolonged cloudy weather, plants can stretch. Root crops in this case are formed small. Therefore, for growing a crop, additional illumination with special lamps may be necessary. In shady conditions and with a dense planting, the green part of the plant will grow, and root crops may not form. For radishes, thinning or planting with markings is mandatory, one seed per hole.

The soil for growing radishes in a greenhouse should always be kept moist. With a lack of moisture, root crops coarsen, lose their taste, and remain small. Subsequent waterings will not be able to make up for the lost qualities of the product. Air humidity is also important for crop growth - with the predominance of dry air, vegetables lose their taste, become flabby, porous.

Interesting. In a young radish, all parts are edible: foliage before it becomes coarse and thinned seedlings-tails. All parts of the radish at the beginning of the growing season are used in fresh or subjected to heat treatment.

Radish will grow well on loose soils with low acidity, sandy loams and loams. Infertile severe or sandy soils do not fit the culture. For rapid growth and the formation of root crops requires a high content of organic matter in the soil, its ability to pass water well.

Radishes should not be planted in the same soil every year. The soil should be changed to avoid the accumulation of diseases. good radish grows after cucumbers and tomatoes, but not after cabbages. The culture does not tolerate the proximity to tomatoes, so they are not used in joint plantings.

Seed preparation

radish seeds light brown, have a round shape. To select the best specimens for landing, they are manually calibrated. When processing a large number seeds planting material sifted through a coarse sieve. For planting choose only large full-weight seeds. When choosing seed material it is important to pay attention to the terms of its storage. Old seeds give a poor harvest.

For radish seeds, it is productive to soak them in a natural, nutritious infusion of ash. Such an infusion is prepared from 2 tbsp. l. ash and 1 liter of water, left for two days. Seeds in ash infusion are kept for 12 hours. The solution saturates the seeds with microelements and accelerates their germination.

To speed up the emergence of seedlings, radish seeds are pre-sprouted. To do this, they are kept in a layer of damp cloth in a warm place. After small sprouts appear, the seeds are ready for sowing in the ground. Germination of seeds gives an idea of ​​their germination.

Greenhouse preparation

An unheated version of the greenhouse is suitable for growing radishes, robust design, accumulating heat from the spring sun and thus allowing you to heat your space. Designs that use a polycarbonate sheet may be suitable. Sheet cassette - 40x40 cm in size. A light greenhouse is also suitable, in which the film serves as a covering material.

Soil preparation for planting radishes in a greenhouse is carried out in the fall. After the harvest of the current year, everything is removed from the greenhouse plant remains, renew the soil layer. Fertilize, loosen. If radishes are grown in separate containers, then the soil for them should also be prepared in the fall.

In the spring, after warming up the soil by several centimeters, the soil is loosened with a flat cutter, leveled with a rake. Dry soil is shed warm water over the entire area, waterlogged - dried.

Interesting. A greenhouse for growing radishes should be ventilated and well ventilated.

High temperatures, above +35°C, are not suitable for growing radishes in protected ground.

In a greenhouse, radishes are usually planted not as a main crop, but more often as a row-spacing compactor. Sow an early crop also separate section or along the edge of a ridge. When planting, you should also be guided by which plants will be transplanted into the greenhouse next in order to avoid shading the radish with them.

Sowing seeds

Mid-spring is the time when radishes are planted in polycarbonate greenhouses. The harvest will ripen by mid-May. But Krasnodar region and Siberia differ in landing time. Focusing on moon calendar for different regions, planting seeds early varieties vegetables here are the months of March-April. Planting time also depends on the warming of the soil and how the winter was. Radish sprouts most favorably at +20°C. When sprouts emerge, but before the first true leaves appear, the temperature is reduced to + 8 ° C so that the plants do not stretch excessively. After the appearance of true leaves, the temperature is raised to + 18 ° C during the day, + 15 ° C - at night.

Sowing seeds, a convenient way

For planting, shallow furrows or holes are planned. The furrows are well watered before planting. Germinated seeds should be sown with great care so as not to break the small shoot. In the furrow, the seeds are laid out with a distance of 5 cm. This method will not require further thinning of seedlings. The distance between the furrows is 20 cm. Such a distance must be left so that the radish has a sufficient feeding area.

Seed planting scheme:

• Planting can also be done with dry seeds. Before planting in the holes, you do not need to scatter the ashes.
• From the place where the main crops will be planted, the seeds should be planted at a distance of 10-15 cm.
• After planting, the holes are covered with air nutrient soil no more than 1.5 cm and lightly pressed.
• Planting can be watered with a microbiological preparation diluted in water against fungal and bacterial diseases.

Features of spring planting

Radish is a culture of long daylight hours; in its biological cycle, growth ends with flowering and seed formation. Root crops appear in conditions of short daylight hours, which is ensured by early sowing and low air temperature. Radish during this period grows well until June. greenhouse early sowing well suited for growing crops. You can do several plantings of seeds with an interval of 2 weeks and get 2-3 crops per year.

Radishes in a greenhouse in the spring without heating are safely grown in the Urals, in Tyumen, adhering to general recommendations for cultivation of culture. Sowing begins in mid-April. Landings are additionally covered with a film. When seedlings appear, the shelter must be immediately removed and the temperature in the greenhouse reduced until the first true leaves appear.

In the northern regions in a good way receiving high yields greenhouse vegetables will make the device warm high beds. This bed is prepared from the previous season. Biological method preservation of heat inside the ridge is achieved by placing various organic residues between the soil layers: cut grass, rotted manure. Introduced materials having vegetable origin must be healthy. Residues from infected plants are not used. The process of decay of organic matter inside the soil provides not only its heating, but also enrichment with nutritious and useful microelements.

Planting in a greenhouse in spring

When pulling the plants, the ground around the seedling is sprinkled. A column not covered with earth, which is located below the cotyledon leaves, does not form a root crop, and the seedlings lie down. The subcotyloid knee should be no higher than 4 cm above the ground.

Crowded plantings are not allowed; thinning should be carried out on time.

When using additional illumination of plants with lamps, they should be turned off in a timely manner, forming an optimal light lighting around 11-14 hours during the day. With constant illumination, the plant does not form a root crop, but leaves in color.

Additional Information. When growing radishes in separate containers, it is important to consider the height of the soil layer. The soil should be at least 20 cm, especially when choosing elongated radish varieties.

At high humidity in a greenhouse, seedlings can be struck by a black leg - fungal disease root system. Therefore, constant ventilation is necessary for culture. For growing crops High Quality the soil must be constantly moist. Optimal Humidity- about 70%. Check proper watering soil can be squeezing a handful of earth in your hand. When compressed, the earth should be well pressed, and when unclenched, it should crack.

The fragrant root crop belongs to unpretentious crops, but requires compliance with certain growing conditions. Planting and caring for radishes in a greenhouse can be easily done in regions with different climates. At proper cultivation radish pulp is juicy, crispy, without voids.

culture care

When growing radishes, drying out of the soil, coarsening of its upper layer is not allowed. Plants should be watered with warm water, temperature + 20 + 25 ° C. At the beginning of growth, watering is carried out frequently, with the advent of seedlings, the intervals between waterings are increased, as is the volume of water used. From uneven watering, root crops crack and lose their juiciness. The soil can be moistened by spraying.

After watering, the soil must be loosened, if necessary, weeds are removed, the greenhouse is ventilated. In warm weather, ventilation is increased, and with the establishment high temperatures the greenhouse is not closed at all or the windows are left open.

Radish is responsive to fertilizers. The plant is fed sparingly. Complex mineral fertilizers are what you can feed radishes after germination in greenhouses. For early varieties, the presence of phosphorus and potassium is important. Re-feeding is carried out, focusing on the appearance of the plant. When the color of the leaves has become pale green, the plant does not add growth, then it is necessary to feed the radish organic fertilizers in liquid form, such as slurry or ash solution.

Important! An excess of fertilizer enhances the growth of above-ground green mass, while the root crop remains undeveloped.

Spinach, planted next to radishes, helps against damage to root crops by pests.

Radish Zhara - early ripening

Early maturing varieties, optimally suited for growing in greenhouses, mature in 20 days. Radishes can be collected selectively. It is not worth delaying with the general collection beyond the established deadlines related to a particular variety. Root crops that have sat out in the soil lose their taste and juiciness, become fibrous.

For better storage harvested crop water it in the evening. And the next day, in the morning, when it is still cool, the radish is completely harvested. Root crops not watered the day before harvest lie poorly and dry out quickly. The harvested vegetables are cut off the tops, leaving a stump and roots. Cropped root crops are slightly dried in the shade. Store radishes in the lower compartment of the refrigerator, in an open bag, for up to one week.

Radishes can be a capricious crop. Some gardeners, no matter how much they grow, have no crop, while others have nowhere to put it. But by studying the methods of agricultural technology of culture, gardeners can learn something new for themselves and also rejoice at the first vitamin vegetables.

One of the first vegetables to be harvested in the country is radish. Thinking about this vegetable, one immediately comes to mind fragrant spring salads and, of course, okroshka on natural bread kvass. Today, there is no problem finding Israeli or Egyptian radishes on the shelves. But all this is not right, I want a native, fresh, from my own garden and as soon as possible.

In 2014, we bought and installed a rounded 4 m polycarbonate greenhouse on the site. The first thing that was planted in it in 2015 was a radish. Landing was carried out in the second half of April. Before that, compost was added to the soil and dug up well upper layer soil, after which they leveled it. The acidity of our soil is close to neutral, it can be slightly acidic.

Be sure to carefully consider the choice of planting material. Seeds should be quite large - with a fraction of at least 2.5 mm. In polycarbonate greenhouses, you can safely plant the following proven varieties: "Early Red", "Silesia", "Dawn", "Rova", "Helro" and "Warta". Each of these varieties has early dates harvest ripening.

When planting, expect that about 5 g of seeds should be planted per 1 m2 of greenhouse area. It is advisable to sift them through a sieve with a cell of 2 mm before planting. Additionally, I advise you to treat the planting material with a weak solution of potassium permanganate to prevent the development of various infections in seedlings.

Spread the seeds over the surface by eye. It is better to spend a little more time and immediately arrange them evenly. In this case, you will not need to spend a lot of time on thinning in the future.

For planting, I make parallel rows-grooves at a distance of about 6 cm from each other, each with a depth of about 1 cm. In each of them I spread the selected seeds at a distance of about 2 cm from each other. They germinate well already at a temperature of +2 ... +4 C. But the most comfortable for the growth and development of plants are indicators at damage from +16 to +20 C.

After the start of mass germination, it is advisable to lower the temperature inside the greenhouse for 4-5 days to + 6 ... + 8 C so that the sprouts do not stretch very much at the beginning of growth (otherwise they will be weak).

small return frosts you don’t have to be particularly afraid, radish tolerates short-term temperature drops down to -5 C without consequences.

An important point in growing radishes in a polycarbonate greenhouse is to protect the crop from pests. You can treat with various insecticides, but I prefer natural proven products such as tobacco dust and wood ash(I mix them in equal proportions).

If, despite all the preparations, the seedlings are too thick, be sure to thin them out. Otherwise, neighboring plants will begin to shade each other, and the volume of the “food base” for root crops will be insufficient (leave about 2-3 cm between the “neighbors”). If you neglect this rule, you will most likely get an inexpressive small radish.

Radishes in polycarbonate greenhouses should be watered as the topsoil dries up, about 1 time in 2-3 days. If you skip the next watering, then your radish will harden and will almost certainly crack in the future. Therefore, if there are problems with the frequency of watering, mulch with a layer of peat or humus. In this case, the soil will lose precious moisture much more slowly.

I also strongly advise you to ventilate the greenhouse after each watering, otherwise the black leg can “sneak up” imperceptibly. So that the plants develop well twice during the vegetative period, I apply nitrogen fertilizers (25 g per 1 m2).

Radish is the first vegetable that is received from the garden in May. Root crops contain a lot of fiber, enzymes, fats, vitamins B1, B2, C and PP, sodium, calcium, iron, phosphorus, proteins. This is an unpretentious culture, even a novice gardener can handle it, and our article will help him.. If you plant the seeds in a sunny place shortly after the snow melts, then shoots will appear in a few days. The best harvests gives the cultivation of radishes in a greenhouse.

The soil is prepared in advance, in the fall. Mineral fertilizers contribute at the rate of 40 g of superphosphate, 15 g of potassium chloride per m². The ground must be neutral acidic soil the radish is starting to hurt. If it is not rich in organic matter or depleted by the previous crop, add an additional one and a half buckets of compost for every m². After that, the soil is dug up, leveled, left until spring. In advance, you need to prepare ridges 1m wide.

The soil for radishes is carefully prepared

Sowing radish

Now let's move on to the selection of seeds. Success depends on the correct choice of variety, since not everyone is suitable for this purpose. Greenhouse (optimal for growing in spring, resistant to bolting), Zarya (stress-resistant variety), Heat (ideal for early forcing), Saxa (early ripening, time from sowing to harvest - less than a month), Early red (created for growing in winter greenhouses).

Picking up varieties different term maturation, you can extend the harvest

Radishes can be grown all year round if there is a heating system. Conditions middle lane do possible cultivation in winter, even if the greenhouse is not heated. For planting in the spring, already in March, in about 1-2 weeks, you need to put the greenhouse in order, clean off the snow, if necessary, repair the frame and stretch the film. This will help the soil thaw faster. After the top 3-5 cm of the soil becomes soft, planting radishes is already possible. Those who have not prepared the beds since the fall will have to wait for complete thawing, fertilize, dig, level, and then start sowing.

Seeds are calibrated before planting.

To grow radishes good quality from seeds, before sowing, they should be sieved through a sieve with a mesh size of 2 mm. This will allow you to select the best planting material. It is useful to treat the seeds with potassium permanganate to reduce the chance of diseases. Sowing is carried out manually, the distance between seeds should be 1-2 cm, between rows - 6-8 cm. Consumption will be approximately 4-5 g per m². The more evenly spaced the seeds, the less they will need to be thinned out. Embedding depth - no more than 1 cm.

seedling care

Successful cultivation radish requires optimal mode temperature and humidity. In a greenhouse, maintaining them is not so difficult. During germination, the temperature should be 16-18°C. When mass emergence of seedlings begins, the room is cooled to 6-8 ° C to prevent seedlings from pulling out. At this temperature, seedlings can withstand 3-4 days. After this period optimum temperature cultivation is 15-20°C during the day and 8-10 at night. Frosts do not pose a danger to this crop if the temperature at night does not fall below -5 ° C. Processing the beds with ash and tobacco dust in a ratio of 1: 1 will protect the fruits from pests. If the seedlings are too dense, they must be thinned out. It is desirable that the distance between plants does not exceed 2-3 cm. When crowded or shading, the roots do not grow, they remain small. After thinning, the leaves take horizontal position, this reduces the likelihood of shooting.

Seedlings require special care - thinning and airing

Water as the soil dries up, spilling it 10-15 cm deep, usually this has to be done every 2-3 days, but in hot weather every day. This culture is very demanding on the regularity of watering. From drying, the roots begin to coarsen, and if after that they are immediately filled with water, they will crack. The soil is sprinkled on top with peat or humus, with a layer of no more than 1 cm, this procedure will reduce the evaporation of moisture, retain it in the soil. After watering, ventilate well - due to the high humidity of the air, the radish can get sick with a black leg. Together with watering 1-2 times, it is desirable to carry out top dressing nitrogen fertilizers, making them at the rate of 20-30 g per m². The aisles are weeded and loosened as necessary.

Formation of root crops

The formation of root crops occurs even at a temperature of 12 ° C. In the summer, the greenhouse is covered with a dark film in the evenings so that the daylight hours are no more than 12 hours, otherwise flower stalks form, there will be no normal harvest. 35-45 days after sowing, the size of root crops in radishes should be more than 2 cm. Harvesting is carried out in 2-3 steps, the total yield is at least 1.5-2 kg per m².

Harvesting radishes is a pleasant experience

Radish is a healthy, tasty and easy-to-grow crop that, with little effort, can give good harvest. The question of when to plant radishes in a greenhouse does not really exist. This crop can be safely grown from spring to autumn. For this, the seeds are sown every 20-25 days, last landing can be made in the last days of August.

This culture can be on the table all year round

Root crops keep well if laid out in plastic bags(1 kg each) place in a cool place. Several crops during the growing season, compliance with crop storage conditions will allow you to have on the table useful product throughout most of the year.

Growing radishes in a greenhouse is not associated with great difficulties, since this root crop is unpretentious. Sheltered radishes will be protected from severe frosts and other weather vagaries that are common in many regions.

In addition, radishes in a greenhouse can be planted at any time of the year, thereby providing yourself with such a useful and wholesome crop all year round. rich in vitamins and microelements of culture.

Consider a few important points this way of growing

• First, as for any vegetable crop, you must first select the best varieties radish for greenhouses;
• secondly, the seeds and the greenhouse itself should be properly prepared for growing;
• and, thirdly, it will not be superfluous to get acquainted with some features of planting and caring for radishes in closed ground.

Varieties

Since the greenhouse is usually used for more “solid” crops, such as cucumbers or tomatoes, radish is often allocated a place in it on a residual basis. For example, you can sow a greenhouse with radishes at the very beginning of the spring season, for the period of growing seedlings of that vegetable, which will then take the place of radishes.

• "18 days". This variety is not in vain got its name. It really ripens and allows you to harvest already 18 days after planting and, in addition, it has a pleasant mild taste.
• "Firstborn F1". Those for whom productivity is important, this particular variety will delight with its large round root crops.
• "Baby F1". This hybrid matures in less than three weeks and compares favorably with its resistance to shooting.
• "Ultra Early Red". This greenhouse-friendly variety is unique in that both tops and roots are edible in it: that is, both the root and the leaves, which will become an original ingredient for any vegetable salad.

For those who are not in a hurry and are willing to wait a few days for larger fruits or special palatability, other early ripe varieties are also suitable:

• "Heat". This variety is very often grown in film greenhouses, it matures quite quickly and does not require special care.
• "Early Red". From other varieties of radish, this one is even more unpretentious to light conditions and soil composition. It matures in 22–24 days and produces large and juicy root crops.
• "French Breakfast". Root crops of this variety ripen quickly and are stored for a long time, without losing their taste, remaining all the same juicy and sweet.
• "Helro". Designed for indoor cultivation, many used for planting in polycarbonate greenhouses.
• "Dawn". It ripens quickly, the first harvest can be harvested after 20 days. This radish is great for growing in a greenhouse.
• "Greenhouse". The name of the variety speaks for itself, it is intended specifically for planting in protected ground.

AT summer period radishes are best grown on open garden, and you can re-sow some varieties in the vacated greenhouse in the fall, after harvesting the main crop.

For autumn sowing, varieties are suitable that ripen a little longer, but are more resistant to autumn changes temperature and light mode:

• "Autumn Giant"
• "Soffit"
• "Basis"
• "Ice Icicle"
• "Würzburg 59"

Another advantage of many autumn varieties is their long shelf life, which allows you to prepare some stock of this tasty root crop for the winter.

Preparing for landing

Landing and care

+ 17 - +19 degrees is considered the optimal temperature for growing this crop in greenhouse conditions, but seeds can also be planted at + 10. Radish is resistant to cold. Seeds are planted in shallow holes or grooves at a distance of 2-3 centimeters from each other in even rows, the distance between which should be at least 8 centimeters. So that the radish does not start shooting, after the appearance of the first sprouts, the temperature in the greenhouse must be reduced for several days, and then returned to the optimal value again.

Radish - photophilous plant, so when grown in early spring, late autumn and in winter, when the daylight hours are much shorter than in summer, LED or fluorescent lamps. They need to be turned off periodically, since with an excess artificial lighting radish can begin to shoot, and all of it Vital energy will go not to the formation of the root crop, but to the growth of the leaves.

Caring for plants in a greenhouse is not difficult. Radishes should be watered regularly, but not flooded at the same time so that they do not rot. A couple of days after the emergence of seedlings, the plantings are thinned out, leaving the most healthy and largest plants.

The last stage is harvesting. Root crops are harvested selectively, allowing some to grow, and not allowing others, already ripe, to rot in the ground or overripe.
