Turnips and radishes are cold-resistant crops, so they start to be sown in early spring. During the spring-summer period, the crop is harvested more than once, and early-ripening varieties begin to be consumed in late spring. One of the factors that affect the harvest is timely planting. The dates depend on weather conditions, varietal characteristics, and a favorable period, which can be determined by the sowing calendar of 2021.
The dates when it is best to plant turnips and radishes in the open ground depend on the weather conditions of the area, varietal accessories (early-maturing, medium-and late-maturing varieties), and cultivation goals. For summer consumption in most regions, radish planting begins in mid-April, to the South – in mid-March. In August, they are planted in the first decade of the month, so that the crop has time to ripen before the cold weather. It is better to plant turnips in temperate climates for summer use from the end of April to the beginning of June, for winter storage – in the first decade of July.
Turnip and radish planting calendar in 2021
Seeds of root vegetables, including turnips and radishes, are recommended to be planted in the ground on the waning moon. This period is favorable for the germination and formation of root crops. Unfavorable is the day of the new Moon, full Moon and days when the moon is in the barren sign of Aquarius. Based on the 2021 planting calendar and weather conditions, you can always choose a date that is favorable for planting.
|A month||Favorable days||Unfavorable days|
|March||1-8, 12, 29-31||9-11, 13, 14-27, 28|
|April||1-5, 8-11, 28, 30||6, 7, 12, 13-26, 27|
|May||1,2, 5-10, 27-31||3, 4, 11, 12-25, 26|
|June||2-9, 25-30||1, 10, 11-23, 24|
|July||1-9, 25-31||10, 11-23, 24|
|August||1-7, 23-31||8, 9-21, 22|
In late August and early September, you can sow in a greenhouse or in a film greenhouse where the climate allows. There is no point in planting later – the root vegetables will not have time to ripen.
Seeds dropped into the ground germinate under certain conditions, so planting turnips and radishes in the spring begins when the weather conditions are suitable for this. Later, when the soil is already warmed up, the temperature regime is also important, especially for radishes.
The peculiarity of radish as a vegetable crop is a short growing season. From the moment of sowing to the first harvest, on average, it takes about four weeks. To ensure that the vitamin vegetable is always on the table, you can plant it at intervals of 1-2 weeks from March to June, then in August.
The second feature is a plant of short daylight hours. The optimal length of daylight hours is 10-12 hours. When the day gets longer (June-July), and the temperature rises to 25 °C and above, the radish blooms (shooting). The forces of the plant are directed at flowering and seed formation, so the fruits grow small, hard. They resume sowing in August.
The reason for shooting can be the thickening of crops, drying out of the soil, prolonged exposure to low temperatures. It is also not recommended to apply ash and potash fertilizers.
Seed germination begins at +3-4 °C, but development will be slow. If you cover the ridge with agrofibre, film, which is done in the spring, then the temperature can be increased. After the emergence of seedlings, the shelter is removed during the day so that the development of the tops does not go to the detriment of the development of the root crop, and it is closed again at night. When stable temperatures are established, no shelter is required.
For the formation and development of root crops, the optimal temperature during the day is +18 °C, at night-from +8 to + 10 °C, the soil should not cool below +15 °C. In late July and August, daytime temperatures are still high, so they resort to watering with cold water to reduce the amount of heat. From the 6th to the 20th day after sowing, it is necessary to maintain a moderate temperature regime and not artificially shade the ridge, so as not to provoke flowering.
During spring sowing, the soil should thaw by 3-4 cm, so to speed up the process, the ridge is spilled with hot water, covered with a film. Small short-term frosts from -4 to -6 °C are not terrible for crops – growth will stop, but this will not affect the quality of the crop. A prolonged drop in temperature is disastrous for seedlings.
Site and soil requirements:
- for spring sowing – an open Sunny place, for summer – shaded in the afternoon, in autumn-a bright place throughout the day;
- it is convenient to sow radishes between crops that ripen later (carrots, onions, celery);
- the soil should be light, loose, and fertile (looseness is added by adding sand, fertility is increased by adding compost, humus, and voids are formed from fresh manure in the root crop).
Like radishes, turnips belong to frost-resistant crops-they plant it when the ground warms up to +3-5 °C, frosts from -2 to -3 °C are not terrible for seedlings of frost-resistant varieties. But with unstable weather and frequent thaws in the winter, it is better not to sow-the seeds can germinate, and the shoots will die. Turnips, unlike radishes, are a long daylight culture.
For use in summer, turnips are sown from April to the end of may with an interval of 10-15 days. For winter storage – in July, choosing the right variety and taking into account the climate of the region. For seed germination, the optimal temperature is 8-10 °C, for root crop development-12-20 °C. At high temperatures, growth is inhibited.
The temperature of the soil for germination is 3-5 °C, and the temperature of the air is 15-18 °C. A seedling method of growing is possible – seedlings are planted 6-8 weeks before transplanting to the ridge.
If a low temperature is kept for a long time during the germination period, this can lead to the appearance of peduncles, which reduces the taste of the root crop. An adult plant can withstand autumn frosts from -4 to -8 °C, but they will affect the shelf life.
- lighting – the crop is demanding of light during the emergence period, the growing season is shortened when the light day becomes shorter (you need to take into account the variety affiliation);
- the soil should be moderately moist – stagnation of moisture and drying out negatively affect the quality of root crops, during the emergence period and a month before harvesting, it should not be allowed to dry out;
- the best soil option is light sandy loam, loamy, cultivated peaty land;
- top dressing – excess nitrogen affects the quality of fruits, the duration of storage.
