Chinese Red

Radish

25d to harvest

Sweetly crisp and vividly peppery at once, Chinese Red radish forms a jewel-bright red globe with a clean, snowy interior that snaps with every bite. At about 25 days from sowing, its tender texture stays pleasantly fine—ideal for fresh, quick salads and vibrant garnishes where color and crunch matter most. Grow it for that first-spring burst of flavor: a refreshing bite that livens up simple plates and makes every harvest feel like a small celebration.

Frequently Asked Questions

What pest or disease commonly affects Raphanus sativus (Chinese Red) and how do I control it?

Flea beetles frequently chew small pits in radish leaves, which can stunt plants within a week. Use insect netting/row cover immediately after sowing and keep it on until most plants are well established; if damage is heavy, treat with an insecticidal soap and reapply per label after new feeding starts. For disease, watch for damp, collapsing stems from poor airflow—water at the soil line and avoid overcrowding to reduce damping-off and leaf spotting.

How often should I water Chinese Red radishes during the main growing phase?

Keep the soil consistently evenly moist from germination through bulbing (roughly the first 2–3 weeks), not soggy. Water deeply when the top 1 inch of soil dries, typically about 1 inch per week total depending on heat and wind; more frequent light watering can help in hot spells but avoid waterlogging. Uneven moisture can cause cracked or woody roots, so aim for steady moisture rather than irregular soak-and-dry cycles.

How can I tell when my Chinese Red radishes (Raphanus sativus) are ready to harvest?

Harvest when the roots are about 1–2 inches across (for many Chinese radishes) and feel firm, usually around 25 days after sowing. Don’t let them sit too long after they size up—overmature radishes can become pithy or stronger-flavored. If you’re unsure, gently pull one and check the root diameter before harvesting the rest.
