When to plant radishes in a polycarbonate greenhouse in early spring: in March, in April, in the Moscow region, in the Urals, in Siberia, according to the lunar calendar

In early spring, it is still quite cold in many regions of Russia, however, the increasing daylight hours and the sun beginning to noticeably warm up already make it possible to carry out some agricultural work. Planting radishes in a greenhouse in early spring is one of the most common ways to start your gardening season. It allows not only to get early vegetables, but also to reuse the greenhouse by planting cucumbers, tomatoes or peppers in it after harvesting root crops.

Benefits of early planting of radishes in a polycarbonate greenhouse

Radish traditionally begins the gardening season. This culture is characterized by resistance to low temperatures and unpretentious cultivation. Radish has quite a few varieties with ripening periods of less than 1 month, so this crop is the best suited for early sowing in greenhouses. Radish seeds can sprout at temperatures from + 3 ° С and above, however, the plant can grow and develop normally at temperatures from + 10 ° С. In structures based on polycarbonate, it is quite possible to provide such conditions already at the beginning of spring. Therefore, sowing radish in such greenhouses can be done already in March-April.

Polycarbonate is an excellent thermal insulation material, quite lightweight and durable. It transmits light perfectly. The bright spring sun quickly warms up such a greenhouse, and the porous structure of polycarbonate retains heat for a long time.

Radish varieties for early greenhouse planting

For growing radishes in a polycarbonate greenhouse in the spring, ultra-early and early varieties with ripening periods of about 3-4 weeks are chosen. Thus, by the middle or end of May, the crop ripens completely. This allows you to carry out all the necessary work on processing the greenhouse and prepare it for planting more thermophilic crops, which are planted in late May or early June.

The following radish varieties are suitable for early planting in polycarbonate greenhouses:

  • Firstborn F
  • CelesteF
  • Ultra early red.
  • Early red.
  • Heat.
  • French breakfast.

When to sow radishes in the greenhouse

It is possible to plant radishes in polycarbonate greenhouses in spring in many regions by the end of March and by the beginning of April, the ground inside them completely thaws by this time, and the air temperatures do not drop to negative values ​​even at night. When the soil warms up to + 5-7 ° C, you can start sowing radish seeds. Sowing can be carried out even earlier in greenhouses with individual heating.

In the heated

In heated greenhouses, radishes can be grown all year round. However, it must be remembered that a short daylight hours in winter are clearly not enough for the normal development of plants, therefore, in such structures, in addition to heating, it is imperative to equip additional artificial lighting.

Into unheated

It is difficult to name the exact dates for planting radishes in greenhouses in spring without additional heating, since each region has its own climatic features. In this case, you need to focus on the air temperature in the greenhouse. If it does not fall below 0 ° C even at night, then you can start landing.

When to plant radishes in a greenhouse in the regions

Due to the peculiarities of the climate of various regions of Russia, the timing of planting radishes in unheated greenhouses is shifted to earlier or later ones. In addition to temperature indicators, solar activity is also of great importance. Both the yield and the ripening time of vegetables directly depend on the number of sunny days, because it is the energy of our luminary that heats the air and soil in unheated greenhouses.

In outskirts of Moscow

You can sow radishes in a greenhouse in the Moscow region at the end of March. At this time of the year, there is no snow cover in most parts of the capital region. Thanks to good solar activity, the ground in polycarbonate greenhouses by the beginning of April is already warming up enough to start planting radishes. If the spring is late (which is not uncommon for the Moscow region), then planting can be carried out 1-2 weeks later.

In the Urals

The climate of the Urals differs significantly from that of the Moscow region. However, when planting radishes in a greenhouse, this difference is largely eliminated. The Ural region is large enough, therefore, the timing of planting work here strongly depends on the geographic features of the area and solar activity. You can start planting radishes in a greenhouse in the Urals in April, additionally focusing on local climatic conditions.

In Siberia

In Siberia, the snow cover can last for a long time. However, in the southern regions, due to the abundance of sunny days, greenhouses warm up rather quickly. In mid-April, the ground in the greenhouse is already warm enough for planting radishes, but it is imperative to take measures to protect against low temperatures in the dark, since the likelihood of night frosts at this time is still extremely high.

When can you plant radishes in a greenhouse in spring according to the lunar calendar?

Many gardeners and gardeners believe that it is possible to properly plant radishes in a greenhouse in spring only by focusing on the lunar calendar. This practice can be treated in different ways, but the influence of our natural companion on the growth and development of plants undoubtedly exists. It is believed that on the growing moon, the aboveground part of plants develops more intensively, the waning moon contributes to the development of the root part.

The full moon and new moon phases are dormant periods, at which time it is not recommended to disturb the plants.

In March

Since the radish crop ripens underground, you need to navigate when planting on the days on which the moon is in the waning phase. Based on this condition, as well as taking into account the passage of the Earth's satellite through the zodiacal constellations, the most optimal days for the spring sowing of radishes were determined. In March, these days are 1, 5, 23, 25, 28 and 29.

In April

For sowing radishes in greenhouses, April 2, 20, 23, 25, 26 and 29 are favorable. However, this does not mean that if you sow on other days, there will be no harvest. The lunar calendar is just one of the factors affecting the yield of garden crops. It would be wrong to focus only on it, without taking into account the peculiarities of the climate of the region or weather conditions.

Greenhouse preparation for planting

Cleaning, washing and disinfection of polycarbonate greenhouses is carried out in the fall, after harvest. If the structure was not used during the winter, then re-processing is not necessary. It is also better to dig up the ground in the fall, it is better to combine this with the introduction of organic matter and mineral potash-phosphorus fertilizers. Before planting the radish, it will be enough to slightly loosen the soil with a hoe or flat cutter, and then level the beds with a rake.

How to plant radishes in a greenhouse in early spring

Plant radish seeds in grooves or holes. They should be shallow, 1-2 cm. Place them on the garden bed at a distance of 20 cm from each other. Before planting, the grooves are moistened, and then the seeds are laid in them at a distance of 3-5 cm from each other. Observance of these distances avoids competition between neighboring plants, so the plantings then do not have to thin out. After planting, the seeds are sprinkled and watered again.

Important! To plant radish seeds evenly, it is very convenient to use the old egg grate, using it to make depressions in the ground.

How to grow radishes in a greenhouse in early spring

Radish is quite unpretentious, however, certain care measures still need to be taken. It is imperative to carry out the following activities:

  • watering;
  • loosening the soil;
  • weed removal;
  • top dressing.

How much radish grows in the greenhouse

Radish rises pretty quickly. The first shoots may appear within 4-6 days from the moment of planting. If the ground is not warmed up enough, seedlings may appear much later. Therefore, do not rush to planting, the intensive growth of the plant will still not begin until the temperature in the soil reaches + 8-10 ° C.

How often to water radishes in the greenhouse

For the radish to grow normally, the soil must be loose and moist, so regular watering is very important. If the weather is sunny, then the ground in the greenhouse dries up pretty quickly. You need to water the radish in the greenhouse every day, making sure that moisture penetrates the soil by 15-20 cm. Lack of watering can provoke the growth of arrow shoots. It is preferable to use water settled and slightly warm, therefore containers are usually placed directly in the greenhouse. During the day, the water warms up and settles well, and in the evening it can be used for irrigation.

Thinning and loosening of soil

The top layer of the soil must be loosened regularly, destroying the resulting crust. This will maintain normal air exchange in the soil, which is extremely important for the establishment and growth of root crops. If the planting was carried out in compliance with the required spacing between seeds, then it is not required to thin out the seedlings. If the plantings are thickened, then culling should be carried out, thinning the plants, and also removing weak shoots.

Periodically, you need to remove weeds, which will feel good in greenhouse conditions and can drown out the planting of radishes, especially at an early stage.

How to feed radishes in a greenhouse

At an early stage, the radishes in the greenhouse can be fed with nitrogen, stimulating the process of increasing the green mass. However, it is necessary to use nitrogen-containing fertilizers with great care, since their excess will lead to uncontrolled growth of the tops to the detriment of the formation of the root crop. After the underground part of the plant begins to tie, you should make

How much radish ripens in the greenhouse

Most gardeners prefer to plant ultra-early and early varieties of radish in greenhouses with a ripening period of 20 to 30 days. However, unfavorable conditions, especially low temperatures, can significantly lengthen the maturation of root crops. It is quite easy to determine the market maturity of a radish, since the top of the root crop is open and above the ground.

Important! You can accelerate the ripening of radishes if you use the seedling growing method.

Some gardeners divide the greenhouse area into several beds, planting radishes on them with different ripening periods or with a planting delay of 10-15 days. This allows you to significantly extend the timing of the harvest, saving the grower from the need to quickly consume or process a large number of root crops in a limited time.

Possible growing problems

Radish is an unpretentious plant, however, when growing it, a number of problems can arise. Here are the most common ones.

  • Soil mismatch. Radish prefers loose sandy loam or loamy moist soils with good air permeability, with a reaction close to neutral. With any deviations from these conditions, changes in the development of plants will be noticeable, expressed in a slowdown in growth, yellowing of leaves, and the appearance of diseases.
  • Disorders in nursing. First of all, this concerns non-compliance with planting dates, significant deviations from the irrigation schedule, violation of the length of daylight hours, non-compliance with the recommended temperature parameters. In this case, instead of forming a root crop, the radish may grow into an arrowhead. An overabundance of fertilizers, especially nitrogen-containing ones, can lead to the same result.

What to do if radish is strongly stretched in the greenhouse

When planted in a greenhouse, radishes can stretch out for several reasons. The most common of these are daytime temperatures that are too high and plantings too thick. To avoid this, it is necessary to regularly ventilate the greenhouse and prevent the daytime temperature in it from rising above + 20-22 ° C. And you also need to monitor the density of crops, carrying out their thinning in time.

Pests and diseases

When growing early radish in a greenhouse, the likelihood of plant damage by pests is low. Many insects are still in the ground during the ripening period of the radish crop, only appearing after hibernation, and therefore only a small part of them can harm the crops.

Various viral and fungal diseases can cause much greater harm to radishes, the appearance of which is usually the result of improper care. Among the most common radish diseases, the following can be noted:

  • Keela.
  • Blackleg.
  • Powdery mildew.
  • Downy mildew.
  • Mosaic.
  • Bacteriosis
  • Gray rot.

The main risk factors are high air humidity at elevated temperatures, as well as thickening of the plantings. To prevent diseases, plantings should be regularly inspected, diseased plants should be removed in a timely manner and sanitized. For the prevention of fungal diseases, various fungicides are most often used, as well as folk remedies: infusions of onions, garlic, celandine, tobacco and other herbs.

Important! A good way to prevent diseases is to inspect and discard the planting material before sowing.


Planting radishes in the greenhouse in early spring allows you to more efficiently use the time and sown area of ​​your personal plot. Plus, it's a good way to increase your vegetable diet by supplementing it with this tasty and healthy root vegetable. Planting and caring for radishes in a greenhouse is quite simple, they do not require special knowledge and skills. You just need to follow the necessary recommendations for growing these plants, and the result will not be long in coming.
