Pearl is the perfect name for this classy, refined, pure white radish. Pearl holds its round shape better than other white varieties, even in less-than-optimal conditions. Mild flavour with a hint of heat. Strong tops for easy harvest and bunching.
Timing: Radishes can be grown all season but they’re easiest when sown just after the last frost date and again at the end of summer and into the fall. Optimal soil temperature: 18-24°C (65-75°F). Seeds should sprout in 5-7 days.
Starting: Sow seeds 5mm (¼”) deep, 25 seeds per 30cm (12″) in rows spaced 30-45cm (12-18″) apart, and thin to 6-12 plants per 30cm (12″).
Growing: Ideal pH: 6.0-6.8. Radishes are moderate to heavy feeders. Best in rich, loamy soil amended with composted manure. Add 1 cup of complete organic fertilizer for every 3m (10′) of row for background fertility. Lime beds the previous fall. The real secret to growing this little vegetable is speed. Sow a short row frequently, thin them quickly, keep them watered, eat them quickly, and sow some more.
Harvest: Harvest promptly when radishes are the size of large marbles. The leaves and developing seedpods are also tasty.
Diseases & Pests: Root maggots and flea beetles can be a problem. Expect to lose 20-30% of your crop to maggots if you don’t use a floating row cover.
