Frequently Asked Questions
What pest or disease is most common on radish (Raphanus sativus) and how can I stop it?
On radish, flea beetles are a common problem—they chew small holes in leaves and can quickly stunt growth. Use row cover right after sowing, and if needed apply an insecticidal soap early in the day to target beetles. For disease, watch for damp-looking leaf spots or mildew and remove heavily affected leaves to improve airflow.
How often should I water radish (Raphanus sativus) during the main growing phase?
Keep the soil consistently moist but not waterlogged from germination through bulbing (about weeks 2–6). In warm weather this usually means watering about 1–2 times per week, or more often if the top 1 inch dries out; aim for even moisture to prevent tough, cracked roots. Mulch lightly after seedlings emerge to reduce drying swings.
How can I tell when radish (Raphanus sativus) is ready to harvest?
Harvest when roots reach the expected size for your sowing row—often around 45 days, but use root size as the main cue. Gently pull one to check: radishes are best when they’re tender and crisp, not when they get pithy or woody. If roots are still small after ~45 days, look for prolonged cold/heat stress and adjust future sowings for more uniform timing.
