Radishes thrive best in light, loose, and well-aerated soil. Heavy soil can hinder the normal development of the roots, so it's essential to prepare the bed in advance.
It is not advisable to dig and loosen the soil during the growth of radishes, as they do not respond well to it. However, mulching the bed with materials like straw can help retain moisture and create favorable conditions for the plant's development.
Proper Fertilization – Without Excess!
Many gardeners make the mistake of adding too many fertilizers to the soil, especially those containing nitrogen. Nitrogen encourages foliage growth at the expense of the roots, so it’s best to avoid using manure, compost, and chicken manure when planting radishes. If the plants require additional nutrients, potassium and phosphorus can be added, but not later than the appearance of the first two leaves. A great option is a solution of monoammonium phosphate (7 g per 10 liters of water) or complex mineral fertilizers.
Protection from Heat and Light
Radishes are a crop that does not tolerate excessive sunlight and high temperatures well. When overheated, they may bolt, which can damage the harvest. To prevent this, it is advisable to shade the beds on particularly hot days using lightweight covering material or setting up temporary structures for sun protection.
