Radish cultivation - sowing, planting, care and varieties: varieties

Radish is still one of the most popular vegetables. The radish owes this to the taste it receives from the mustard oils. In addition, the tuber vegetable has many different vitamins and minerals. The different radish varieties can be divided into two main groups. There are the big radishes on the one hand and the small radishes on the other. The large radishes are divided into red, black and white radishes. The small to medium-sized radish varieties are radishes.

The selection of the variety for cultivation

There are a variety of different radish varieties, many of which can be grown in the home garden. This includes the garden radish, which is about 20 inches long, has the familiar white color and mild spicy taste. Hildis is a blue radish that, in contrast to white radish, is not harvested in summer, but in autumn or winter. This radish has a stronger taste and can be stored for a long time. The variety icicle is a very long radish variety. It is a white variety that grows cylindrically and has a very spicy taste. Last but not least, there is the variety Champion. These are scarlet radishes. Even these small, round radishes have a spicy taste.

The choice of the location and the preparation of the soil

All radishes require a location that is slightly moist and sunny. The soil should be neither too loose nor dry. However, care should be taken before sowing that it has been deeply fluffed and is rich in nutrients. For this purpose, nutrient-rich humus can be mixed under the garden soil before sowing.

The sowing

The sowing of the radish plants usually takes place from the beginning of March. Here, however, the floor should still be covered with a foil. If the soil is still frozen at this time, sowing can take place later until June. The sowing depth should be about two to three centimeters. The distance between the different rows should be about 25 centimeters. If the radish plants have germinated, these should be put in isolated. The early varieties, that is, the ones that are harvested in the summer should be set at a distance of about 20 centimeters. The late varieties need, especially the Japanese Zuchtrettiche need much more space. Here, a planting distance of 30 to 40 centimeters should be maintained. When rearing it is important to ensure that the radish is watered regularly. Radishes can be grown even earlier. Sowing can take place here in February under a foil. From mid-March, the radishes can be sown outdoors without foil. When sowing, care should be taken that the radish seeds are sparingly placed in rows about one centimeter into the soil. The rows should have a distance of about 20 centimeters. Once the plants have germinated, they are isolated. Here is a planting distance of five to ten centimeters must be observed. Again, the germs and plants must always be kept moist. Radishes or radishes can be planted well with beans or tomatoes together. However, care should be taken that there are no cucumbers in the immediate vicinity.

The care of sowing and radish plants

In the cultivation of radish plants the regular and generous supply of water is essential. If the seedlings come out after a week at the latest and are a few inches high, they can be thinned out. With the small radishes, a plant can be planted every five centimeters. When winter radish, however, 15 centimeters per plant are needed. The black winter radish even needs up to 20 centimeters. The soil, if previously enriched with humos or compost, needs no more nutrients. He just needs to be watered regularly. Radish is known as a very uncomplicated plant that can be pulled under a foil even at low temperatures. For example, planting can thrive in March or October.

Pests and diseases of plants

black radish

There are several pests that can cause damage to the tuber or the green in radishes. This includes earth fleas that damage the green of young plants. Nets from fine nonwoven fabric can protect against the earth fleas. In addition, these plants can be damaged by wireworms. The wireworms directly damage the tubers by producing small feedings. In addition, there are several types of bacteria that can damage the plant.

The harvest and the storage

It usually takes less than ten weeks between sowing and harvesting. Usually, the radish can be harvested after eight to ten weeks. Only with the very late varieties one must muster a little more patience.These radishes need about 12-15 weeks to be harvested. However, the tubers should never be harvested until they are fully grown. That's the only way they stay crisp and do not lose their aroma. If radishes are harvested too late, they may become hard and woody. Therefore, the sowing should be made dependent on the harvest time. The radish varieties, which ripen in early autumn or autumn, can be stored in a cool and dry place. This is best done in boxes filled with sand. So the radishes can be stored over the winter. However, the radishes should not be stored on top of each other, as they are so easy to rot. Rotten radishes should be sorted out immediately, otherwise the entire stock can spoil.

Location and soil preparation

Both tubers need a slightly moist and sunny location. Furthermore, a not too loose and not too dry soil is recommended for the cultivation of radishes. For planting radishes, the soil should be deeply loosened and rich in nutrients.


From the beginning of March the first sowing takes place in the cold frame or under foil in the field. From mid-April to June you can spread several seeds in the field. The row spacing should be about 25-30cm and the sowing depth about 2-3cm. After germination, the radish should be separated. The distance for early varieties is about 15- 20cm, late varieties and especially the sometimes huge Japanese breeding radishes should be separated to 30- 40cm distance. During rearing, the radish bed must be watered regularly. Radishes can be sown from February in the cold frame or outdoors under foil. From mid-March to the end of September, sowing outdoors is possible. For this, the seed should be sparingly sown in rows, at a distance of about 20cm and covered with a centimeter thick layer of soil. After germination, the plants are separated to about 5-10cm. The sowing and cultivation must always be kept well moist.

Mixed culture & care

Radishes and radishes are well-tolerated vegetables with a medium nutritional requirement. On the neighboring bed can be planted without any concerns tomatoes. In contrast, cucumbers and cruciferous vegetables should not be placed in the neighborhood. A generous supply of the plant bed with water is probably the most important prerequisite for a successful cultivation of radish.

Harvest and storage

About 8-10 weeks is expected at the radishes from sowing to harvest. Late varieties usually take a little longer, so you have to expect 13-15 weeks. The tubers should be harvested even before they are fully grown, so they remain crisp and aromatic. Radishes harvested too late become light woody and hard. The ripening ripening in early autumn can be stored in sand-filled boxes in a cool and dry place. The tubers should be checked regularly during the winter and putrefied specimens to be sorted out. Otherwise there is a risk that the entire stock spoils.

Pests and diseases

Fleas, especially during long heat periods in summer, cause feeding damage to the green of the young plants. Tissue nets protect the plants from the metallic dark blue shining beetles. Wire worms can be recognized by their feeding processes in the tubers, furthermore they can infect the plant with bacteria. For this you put out half potatoes or carrots as bait traps, which must be checked regularly.
