Common Radish Problems

What to watch for — and how to fix it before it spreads.

🐛

Pests

Flea Beetle

Tiny beetles make hundreds of small holes in leaves; seedlings can be badly damaged.

Fix:

Use row covers immediately after sowing; apply diatomaceous earth; sow densely and sacrifice outer rows.

Cabbage Root Maggot

Fly larvae tunnel into roots, leaving rusty tunnels and stunting plants.

Fix:

Use row covers from sowing; delay planting spring radishes until after peak fly emergence.

🍂

Diseases

Downy Mildew

Yellow patches on leaves with gray spores beneath; common in cool, wet springs.

Fix:

Improve airflow; avoid overhead watering; rotate with non-brassica crops.

Black Root

Interior of roots turns gray-black from Aphanomyces fungus; common in wet, acidic soils.

Fix:

Raise soil pH to 6.5–7.0; rotate crops; use certified disease-free seed.

💡

Common Mistakes

Sowing too late in the season

Radishes bolt immediately in heat, going straight to flowers without forming a root.

Fix:

Sow in early spring and again in late summer/fall; avoid sowing when temps will exceed 75°F.

Leaving in the ground too long

Radishes go pithy and hollow quickly after reaching mature size.

Fix:

Check spring radishes starting at day 20–25; harvest when roots reach pencil-width to marble-size.

🌾 Seed Saving Guide

🟢 Easy

✅ Open-pollinated — seeds grow true to parent

When to Harvest Seed

Let plants bolt and seed pods dry completely on the plant until papery and tan.

Processing

Thresh dried pods to release round seeds, winnow to remove chaff.

Seed Viability

Up to 5 years when stored cool, dark, and dry.

Pro Tip

Radishes cross readily between varieties and with wild radish — isolate by 1000 feet for pure seed.
