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

At the beginning of spring, it is still quite cold in many regions of Our Country, but the increasing daylight hours and the sun starting 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 the 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 radishes in a polycarbonate greenhouse

Radishes traditionally start the gardening season. This crop is resistant to low temperatures and unpretentious in cultivation. There are quite a few varieties of radishes with a ripening period of less than 1 month, so this crop is the best suited for early sowing in greenhouses. Radish seeds can germinate at a temperature of + 3 °C and above, however, the plant can grow and develop normally at a temperature of + 10 °C. In structures based on polycarbonate, it is quite possible to provide such conditions already in early spring. Therefore, sowing radish in such greenhouses can be done already in March-April.

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

Varieties of radish for early planting in the greenhouse

For growing radishes in a polycarbonate greenhouse in the spring, ultra-early and early varieties with a ripening period 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 heat-loving crops, which are planted in late May or early June.

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

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

When to sow radishes in a 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 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. In greenhouses with individual heating, sowing can be carried out even earlier.

In a heated

In heated greenhouses, radishes can be grown all year round. However, it must be remembered that a short daylight hours in winter is 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.

In 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 Our Country, the timing of planting radishes in unheated greenhouses is shifted to earlier or later. In addition to temperature indicators, solar activity is 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

It is possible to sow radishes in a greenhouse in the Moscow region at the end of March. At this time of the year, most parts of the metropolitan area are no longer covered with snow. Thanks to good solar activity, the ground in polycarbonate greenhouses is already warm enough by the beginning of April to start planting radishes. If the spring is late (which is not uncommon for the Moscow region), then planting can be done 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 leveled out. The Ural region is quite large, so the timing of landing work here is highly dependent on the geographical 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, snow cover can last quite a long time. However, in the southern regions, due to the abundance of sunny days, greenhouses warm up quite 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 at night, since the likelihood of night frosts at this time is still extremely high.

When can I plant a radish in a greenhouse in the spring according to the lunar calendar

Many gardeners and gardeners believe that it is possible to plant radishes in a greenhouse in the spring correctly only by focusing on the lunar calendar. You can relate to this practice in different ways, but the influence of our natural satellite on the growth and development of plants undoubtedly exists. It is believed that on the growing Moon, the aerial part of plants develops more intensively, while the waning Moon contributes to the development of the root part.

The phases of the full moon and new moon are periods of rest, during this time it is not recommended to disturb the plants.

In March

Since the radish crop ripens underground, you need to focus on the days when the moon is in its waning phase when planting. Based on this condition, as well as taking into account the passage of the Earth’s satellite through the zodiac constellations, the most optimal days for spring sowing of radishes were determined. In March, such 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, then there will be no harvest. The lunar calendar is just one of the factors affecting the yield of horticultural crops. Focusing only on it, without taking into account the peculiarities of the region’s climate or weather conditions, would be wrong.

Preparing the greenhouse for planting

Cleaning, washing and disinfection of polycarbonate greenhouses is carried out in the fall, after harvesting. If during the winter the structure was not used, then re-treatment is not necessary. It is also better to dig the ground in the fall, it is better to combine this with the application of organic matter and mineral potassium-phosphorus fertilizers. Before planting radishes, it will be enough to slightly loosen the soil with a chopper 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 bed at a distance of 20 cm from each other. Before planting, the grooves are moistened, and then the seeds are laid out in them at a distance of 3-5 cm from each other. Compliance with these distances allows you to avoid competition between neighboring plants, so planting then does not have to be thinned out. After planting, the seeds are sprinkled and watered again.

How to grow radishes in a greenhouse in early spring

Radishes are quite unpretentious, but certain care measures are still required to be taken. The following activities must be carried out:

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

How many radishes grow in a greenhouse

Radishes sprouted pretty quickly. The first sprouts may appear within 4-6 days from the moment of planting. If the earth is not warm enough, seedlings may appear much later. Therefore, you should 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 a greenhouse

For normal growth of radishes, the ground must be loose and moist, so regular watering is very important. If the weather is sunny, then the land in the greenhouse dries out pretty quickly. Radishes in a greenhouse should be watered daily, 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 settled and slightly warm water, so containers are usually placed directly in the greenhouse. During the day, the water warms up well and settles, and in the evening it can be used for irrigation.

Thinning and loosening the soil

The topsoil must be regularly loosened, destroying the resulting crust. This will maintain normal air exchange in the soil, which is extremely important for the setting and growth of root crops. If planting was carried out in compliance with the required intervals between seeds, then thinning seedlings is not required. If the plantings are thickened, then culling should be carried out, thinning the plants, as well as removing weak seedlings.

Periodically, weeds should also be removed, which will feel good in greenhouse conditions and can drown out radish plantings, especially at an early stage.

How to feed radishes in a greenhouse

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

How long does a radish ripen in a greenhouse

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

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

Possible problems in growing

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

• Soil mismatch. Radishes prefer loose sandy 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 the leaves, and the appearance of diseases.
• Care Disorders. First of all, this concerns non-compliance with planting dates, significant deviations from the irrigation schedule, violations of daylight hours, and non-compliance with recommended temperature parameters. In this case, instead of forming a root crop, the radish may grow into an arrow. An overabundance of fertilizers, especially nitrogen-containing ones, can lead to the same result.

What to do if a radish stretched out in a greenhouse

When planted in a greenhouse, radishes can stretch for several reasons. The most common of them are too high daytime temperatures and dense plantings. 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 also you need to monitor the density of crops, thinning them in time.

Pests and diseases

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

Much more damage to radishes can be caused by various viral and fungal diseases, the appearance of which is usually the result of improper care. Among the most common radish diseases are the following:

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

The main risk factors are high air humidity at elevated temperatures, as well as dense 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.

Conclusion

Planting radishes in a greenhouse in early spring allows you to make more rational use of time and sown area in your garden. In addition, this is a good way to increase the diet of vegetables, 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.
