Germination Info

Radishes are some of the easiest seeds to germinate. Plant directly in the ground, approximately 1/4" deep, in loose, moist soil. Soil temperature should be above freezing, at least 45F or higher for germination. Germination may be slower in colder soils. Radishes are fairly cold hardy and can be planted as early as a week prior to the date of last frost. Germination time usually runs about 1-2 weeks under ideal conditions.

Once seeds have sprouted, thin plants to 1-2" apart and rows to 8-12" apart.
