A favorite for children’s gardens because quick and easy to grow with minimal fertility requirements.
Culture: Summer radishes may be sown almost as soon as the ground can be worked. Minimum germination temperature 40°, optimal range 55–85°. They emerge rapidly and grow quickly. Sow 1-2" apart, and thin to at least 2" for attractive uniform roots. Use row cover to protect from flea beetles. They develop more pungency in dry heat than in cool moist weather. Ready for harvest at about the size of a quarter and will rapidly get woody if allowed to grow much larger
Culinary: Parboil the greens and roots separately, then eat them together as very early spring salad. And the pot liquor, mmmm…
