Advice from the seed producer and author

Yves Gagnon

Growing conditions for radishes

Radishes reach their best quality in cool weather. They are frost-resistant. Warm, dry conditions induce flowering and contribute to the development of a pungent flavor and fibrous texture. They are therefore best grown in spring or autumn. Some cultivars are adapted to a particular season. Since the small common radish appreciates an increasing photoperiod, it is mainly grown in spring. Black and Oriental radishes respond better to autumn conditions. All radishes prefer cool, loose soils rich in organic matter. To achieve maximum quality, they must be provided with consistent moisture. They tolerate overhead irrigation as long as it is not in broad daylight. The soil for their cultivation is amended with 500 kg of mature compost per 100 m2. The soil must be well supplied with boron, manganese, and copper. A pH between 5.5 and 6.8 is suitable for them.

Radish Crop Rotation

Radishes are often grown in the second year of rotation with plants that require mature compost. Because of their very short growing time, they can also be grown alongside frugal plants at the end of the rotation. Fertilization will then need to be adjusted.

Companion planting of radishes

Radishes can be grown alongside leafy vegetables that require mature compost, as well as carrots, beets, parsnips, and swedes. However, as the species is vulnerable to cabbage maggots, it is often grown under agrotextile in spring alongside turnips and early cabbages, and in autumn alongside Chinese cabbages, which should also be protected from the pest with a floating tarpaulin.
