Radish Sowing Dates

Raphanus sativus L. var. sativus

The radish is a long-day plant; therefore, its sowing dates are strictly limited to periods of short daylight duration to prevent bolting.

In the reference 10 varieties crop Radish, where this is mentioned in the description.

Radishes are classified as long-day plants. When day length exceeds 13–14 hours, the plant rapidly transitions to the generative phase, bypassing the stage of marketable root formation, which makes sowing from mid-May to mid-July ineffective without the use of specialized cultivars and artificial shading.

The optimal sowing periods occur in early spring and late summer to early autumn, when the natural shortening of daylight promotes root development. Due to the crop's cold tolerance, sowing begins as soon as the soil is workable, while a succession planting method at 7–10 day intervals is used to ensure a continuous harvest.
