Care
When you think about how to grow radishes, they do prefer the cooler ends of the season, spring and autumn, and moisture is essential for good root formation. Best sown in staggered lots so you have a continual crop, two weeks apart is ideal.
Like all root crops, radishes are best grown from seed. This avoids root disturbance.
- Seeds can be sown directly about 10mm deep.
- Radish prefer a sunny position in a well drained, well composted soil.
- Water regularly with a liquid seaweed fertiliser.
- Sow sequentially to prolong the harvest season, every three weeks or so.
- One they germinate you will need to thin a little to give them room to grow.
Top Tips on How to Grow Radishes
- Remember to thin them as they germinate to prevent overcrowding, and remember that they need plenty of sun.
- The best fertilizer for radishes is one that is low in nitrogen to prevent excessive leaf growth. We prefer to use our own compost for radishes.
- Radish should be planted while temperatures are still above 10 degrees C.
