If you have become a happy owner of a greenhouse, then the first vegetable crop you can grow is a radish. Radish is the vegetable that is grown in greenhouses all season. Root crops grow rapidly, radishes are not demanding to care, you can grow from spring to autumn. Radish roots contain vitamins B1, B2, C and PP, which the body needs after winter. Radishes are grown both in open ground and in the greenhouse.
An early and bountiful harvest gives cultivation in the greenhouse. The article reads when it is best to plant radishes in a heated and unheated greenhouse in spring, for example, when to sow in the Urals, in the middle lane (Moscow region) and in Siberia, and how to plant properly, at what temperature of the earth does a vegetable grow more comfortable.
Why is a proper landing period very important?
At the time of planting radish affects the temperature of the soil, the environment and the length of daylight hours. Get a bountiful and high-quality harvest is possible only by observing competent planting dates. Radish - cold-resistant culture. It is possible to sow when 3–5 cm of topsoil becomes soft. For seed germination, temperatures of + 2 ° C are sufficient, although the shoots tolerate frosts down to –4 ° C.
Important! The soil for early sowing is prepared in the fall. Make the necessary fertilizers, dig up the beds and align. If the beds are not prepared in advance, then you will have to wait for the land to thaw completely.
Radish - short day plant. With a 10–12 hour day and a temperature of + 8 ° C at night and +14 - 20 ° C during the day, the roots grow properly, in terms characteristic of the variety.
The consequences of wrong timing
Wrong planting time will affect plant development and worsen the future harvest.
- Long cooling will increase the time of plant development, worsen the quality of root crops and cause flowering plants.
- Lighting more than 13 hours, as well as an insufficient level of lighting, leads to the fact that the radish shoots.
What does the term depend on?
When is it best to plant and what temperature is needed radish? Planting dates depend on soil temperature and ambient temperature. A suitable air temperature when planting radish is +15 - 18 ° C during the day, and +8 - 10 ° C at night. The optimum soil temperature for seed germination is +11 - 14 ° С.
Sow radish can be on the beds, which previously grew tomatoes, cucumbers and peppers.
When is the best time to land?
The best months for sowing radishes in a greenhouse are from February to April and from August to November. During these periods, the length of daylight hours and temperature are optimal for the proper development of root crops.
If you grow radishes in the summer, the beds are covered with foil in the evening. In this way, the length of daylight is reduced to the required 10 to 12 hours. The beds should be lit by the sun., but do not dry out, and air humidity is maintained at 70 - 75%.
Greenhouse must be aired. Due to excess moisture on the plants, fungal diseases develop.
It is important to take into account the temperature regime in the process of vegetation of plants.:
- Before germination - + 16-18 ° С, minimum + 10 ° С.
- After the emergence of seedlings, but before the formation of the first true leaflets - +8 - 10 ° C. The temperature is lowered so that the sprouts do not stretch. At this temperature, seedlings can withstand 3-4 days.
- After the appearance of these leaves - + 14-20 ° C during the day and + 8 ° C at night.
If the temperature of the soil when planting is high and the light is low, the radish will begin to increase the tops, and the roots will be rough.
In central Russia (Moscow region), the beginning of sowing radish in late March. When to plant radishes in a greenhouse in Siberia and the Urals? At the same time, radishes are sown in the Urals. In Siberia, the start date of sowing is from April.
And when to sow radishes, depending on the lunar calendar?
Favorable days for sowing radish on the lunar calendar:
- March - from 20 to 23 (Soil temperature - +2 - 3 ° C, ambient temperature - +4 - 6 ° C).
- April - from 6 to 9, 19, 20, as well as from 23 to 26 (Soil temperature - +5 - 7 ° C, ambient temperature - +10 - 14 ° C).
- May - 7,8,9,10, as well as the period from 19 to 24 (Soil temperature - +7 - 9 ° C, ambient temperature - +18 - 21 ° C).
Heated and unheated indoor garden - what's the difference?
Radishes in heated greenhouses are grown in two ways.:
- directly in the ground;
- racking way.
Directly in the ground radish sown if the soil is heated. If the soil is not heated, then choose the second method. But when grown on racks, the greenhouse must still be heated. In greenhouses with heating, you can start sowing radishes as early as January.
The temperature in the upper soil layer is maintained at 10 degrees, and light day is increased with the help of the backlight.
Growing radishes in a greenhouse is so simple that even a novice gardener can handle this task. The main thing is to follow simple rules about the timing of landing, temperature and lighting. A little effort and abundant harvest throughout the year provided.
