For optimal produce, plant the seeds in a soil with a pH between 5.8 and 6.8 that drains well, suggests Burpee.com. Prepare the bed by tilling the soil at least eight inches down. Radishes dislike being transplanted, so plant them in a bed or pot that receives over 6 hours of sun each day. Radish seeds are actually balls that contain multiple seeds. If multiple seeds from a single seed ball germinate, thin out the smaller seedlings to ensure proper space for the radish root to grow.

Radishes germinate very quickly, and most varieties are ready for harvest in less than a month. Radishes are not susceptible to diseases, but watch for damage from root maggots.
