Radishes grow well in most mineral soils, except very light soils that are too wet.
In general, light soils are better suited for growing radishes than heavy soils.
The soil with a pH reaction of 6.0–6.5 must have good water permeability, be humus (in a greenhouse or under a film, and not contain bark, sawdust, or straw).
Plant radishes where tomatoes, cucumbers, potatoes or legumes previously grew.
The soil after these crops will be especially rich in minerals and favorable for the growth of radishes.
Do not plant seeds in soil where turnips, horseradish or cabbage have previously grown.
Feed the radishes in the spring, before sowing the seeds in the ground.
Dig up the area and add about 5 kilograms of organic matter to the soil, as well as 1 kg of ash.
Then the organic matter is incorporated into the soil with a rake, distributing it evenly.
Superphosphate and potassium salt are also suitable as fertilizers, but remember that an excess of nitrogen has a detrimental effect on the roots and taste of the fruit, and the plant itself is prone to the accumulation of nitrates: it is undesirable to feed radishes with simple nitrogen fertilizers (urea or ammonium nitrate).
