Many people think that the cultivation of radish is a simple matter: planted, watered, and wait for the harvest. In practice, everything is a little more complicated. This root crop will require a little more of your attention, especially if you want to grow an early harvest.
You must admit that after the winter, you want to pamper your body with vitamins, for example, fresh lettuce with greens grown on the windowsill and environmentally friendly radish from your own garden bed. Nothing is impossible! After all, the first harvest of early radish can be harvested in April.
Features of culture
The optimum soil temperature for planting early varieties of radish in the greenhouse is 10-12ºС. Friendly shoots appear at a temperature of 15-20ºС.
Radish can withstand a temporary lowering of the temperature to -1-2ºС.
How to grow radishes? We understand this issue in order.
Soil preparation and sowing seeds
Our goal is the April harvest, so we sow the seeds in March, and we grow radishes only in greenhouse conditions.
It is necessary to take care of beds in the fall: add 40 g of superphosphate and 15 g of potassium chloride per 1 sq. Meter to the soil. Organic soil, for example, a compost bucket per 1 sq.m. After fertilization, dig the soil, level and leave until spring.
A few weeks before the estimated planting date, pay attention to the greenhouse: repair the frame, stretch the film. These simple actions will allow the soil to thaw to the moment of sowing, so that the seeds germinate exactly in time.
Before sowing seeds, make grooves 3-4 cm deep, spill them well with water.
The most suitable early early ripening varieties of radish: 18 days, Sachs, Ruby, Dawn, Early red, Okhotsk, Pink-red with white tip.
To speed seedlings, germinate seeds. This is not a complicated process at all: for a few hours, put the seeds in warm water, then put them on gauze, cover with a thin cloth and put in a warm place. As soon as you notice that the seeds have bite, proceed to sowing. We remind you that by this time you should already have a greenhouse ready and a garden prepared.
Seed the seeds into the soil to a depth of 1 cm at a distance of 5 cm from each other. So each plant will receive the necessary amount of light. Make the seeds one by one. Cover them with earth, thoroughly tamp it - this will speed up germination.
If the weather is rather cold, you can additionally cover the beds with any non-woven material, for example, spunbond or lutrasil. Wait for the emergence of the first shoots after 4-6 days. If necessary, thin out: the distance between the plants should be 3-5 cm.
How to water radishes?
Radish loves moisture. Before the emergence of seedlings, water it frequently, but not very copiously (it is best to spray the crops with a spray bottle). With the emergence of seedlings water the plants stronger, but less often (once every few days). After watering, be sure to loosen the soil and ventilate the greenhouse so that high humidity does not ruin your early radishes.
Remember: the lack of moisture is fraught with early grinning radish. As a result, it will become tough and tasteless. But an excess of moisture can lead to cracking of root crops.
How to feed radishes?
After thinning the seedlings, feed the radish with nitrogen fertilizer, for example, urea (2 tbsp per 10 liters of water). At the initial stage of growth, nitrogen is necessarily needed. If this element is not enough, the radish will have a very bad foliage, and the leaves will quickly turn yellow.
At the beginning of the formation of root crops, feed the plants with this solution: 30 g of superphosphate and 20 g of potassium sulfate per 10 liters of water.
Radish harvesting and storage
Harvest the roots of the crop selectively: the first to leave the greenhouse should be ripe heads of radish 2.5 cm in diameter. Carefully move the soil around the roots and pull the ripe specimens out of the tops. Leave a small radish for ripening, again sprinkling it with earth.
Rinse the roots, dry them on paper or a towel and put them in plastic bags without tying them. Store radishes in the refrigerator in the vegetable compartment.
After harvesting the radish, the vacant space of the greenhouse can be taken up with the main crops (tomatoes, cucumbers, eggplants, peppers), and the aisle can be compacted with intermediate crops (watercress, lettuce and radishes, which, by the way, can be grown throughout the season).
So, all your efforts were justified - the first harvest of April was gathered. Now you can actively lean on spring salads from radish and fresh greens. But remember the sense of proportion: it is not recommended to use radish in case of diseases of the digestive system and the thyroid gland.
