Frequently Asked Questions

What pest or disease issue commonly affects Raphanus sativus (long black radish), and how do I control it?

Black radish (Raphanus sativus) in the Brassicaceae family is prone to clubroot, which causes swollen, distorted roots and stunted growth. To control it, avoid planting in the same bed for 4–6 years, keep soil evenly moist but not waterlogged, and if you’ve had clubroot before, incorporate lime to raise soil pH toward ~7.2 before sowing. Watch for leaf-feeding flea beetles early and use floating row cover until plants are established to reduce damage.

How often should I water long black Spanish radish during the main growing phase to get a long, solid root?

During active root bulking (roughly weeks 3–8), keep the soil consistently evenly moist—about 1 inch (2.5 cm) of water per week total, adjusted for rain and heat. Let the top 1 inch of soil dry slightly between waterings, but don’t allow extended drying because that can cause woody roots or cracking. Water deeply so moisture reaches the developing root, not just the surface.
