Read the type, not just the days
Small salad radishes are different from daikon and winter-storage types. The packet tells you which sowing window and root size to expect. Treat days to maturity as a planning clue, not an appointment that ignores weather.
Direct sow and thin
Sow into a prepared bed or a container deep enough for the chosen root. Keep the seed zone evenly moist. Thin promptly so individual roots have room to swell; a dense row of green tops does not guarantee usable roots underneath.
Check before the whole row is ready
Pull one root when it approaches the expected size. Harvest the rest as they become ready rather than leaving a whole sowing in the ground for convenience. Heat, delayed harvest, and stress can reduce eating quality. Use the result to adjust the next sowing.
- Check the radish type and planting window
- Thin the row
- Sample a root before harvesting the batch
Adapt this to your garden.
Use the variety label and local extension recommendations for exact spacing, planting dates, hardiness, and care. This photograph illustrates the plant group; it does not identify or guarantee a particular cultivar. Flower profiles cover ornamental use.
