The annual radish 'Round Black Winter' is an almost forgotten autumn and winter radish variety with round roots weighing 300 to 500g. Fresh, spicy to hot taste. Excellent for storage and eating raw. Ideal for sowing directly, pot cultivation possible, sowing spring-summer, good for mixed culture, harvesting the roots.

 Description 
The 'Round Black Winter' radish is a very old, traditional and annual medicinal and vegetable plant variety from the 18th century. The almost forgotten autumn and winter radish develops round, turnip-shaped and dark brown to black roots, covered with a scab-like skin. The roots weigh 300 to 500 g and form a firm and pure white flesh. The robust plants grow with green, upright, pinnate and bristly hairy leaves. The winter-hardy variety has a fresh, spicy to hot taste and is ideal for eating raw. The roots can be stored for a long time and are also used to make cough syrup due to their immune-boosting properties.

 Sowing by climate zone 
Subtropic climate (Mediterranean) (e. g. B. Portugal, Spain, Italy)
Direct sowing is recommended from January to May and in autumn from September to December. The plants should ideally be planted in a sunny location.
Moderate climate (e. g. B. Germany, Switzerland, Poland)
Direct sowing from July to August is recommended. The plants should ideally be planted in a sunny location.

 General recommendations 
Due to the simple and uncomplicated germination, direct sowing in rows is recommended. Do not sow the seeds more than 1 cm deep so that the roots can develop. The seeds can be sown close together, and by thinning them out later, the small and too densely growing young radishes can be harvested early to give others the space they need to grow.
Winter radish 'Round Black Winter' does not tolerate waterlogging.

 Additional tips 
For a continuous harvest, we recommend sowing the seeds in 3-week intervals. The soil composition determines the spiciness of the tubers. In order to quickly obtain a fine, crumbly and permeable soil with good nutrient and water retention capacity, we recommend incorporating biochar and primary rock flour.

 Type of propagation 
Propagation occurs via seeds.

 Plant care 
Regular watering during dry periods is necessary to minimize the roots from splitting. Occasional weeding helps the young plants develop. Loosened, nutrient-rich and moist soil is sufficient. No fertilization necessary.
