Why Your Radishes Are All Leaf, No Root
Radishes grow leaves but no root when they’re too crowded, too hot, or have too much nitrogen. Thin to 2 inches and plant in cool weather.
Radishes are the fastest vegetable. They’re also the easiest to mess up.
The 3 Causes
| Cause | Sign | Fix |
|---|---|---|
| Crowded | Small or no roots | Thin to 2 inches |
| Too hot | All leaf, no root | Plant in cool weather |
| Too much nitrogen | Big leaves, no roots | Don’t fertilize |
What to Do
- Thin to 2 inches. Most common fix.
