Sow indoors from late winter or sow directly from late spring through to early autumn
Radish can be planted from as early as the soil can be worked. Make successive plantings of short rows every 10 to 14 days. Plant in spaces between slow-maturing vegetables (such as broccoli and brussel sprouts) or in areas that will be used later for warm-season crops (peppers, tomatoes and squash).
Sow thinly, 0.5in (1.5cm) deep in rows 9in (25cm) apart.
Keep moist and thin as necessary. Proper thinning focuses the harvest and avoids disappointing stragglers that have taken too long to develop. Slow development makes radishes hot in taste and woody in texture.
Repeat sowings every two to three weeks to ensure a continuous supply. Remember, it is much more economical to sow little and often rather than have a long row of radishes all coming to maturity at the same time.
