I don't think radish come top of anyones favourite veg list but they are incredibly quick and easy to grow, and that alone justifies some space in most veg patches.
Because they're so fast they're a great 'catch crop' - plants you can grow in ground that's come free for a few weeks between main crops, or you can simply squeeze them in between rows of slower growing plants like purple sprouting broccoli.
Time from seed to plate: 4 weeks
Radish can be sown anytime from April to August. Sow directly into your soil, aiming for one seed every 1/2in or so. Maybe sow one row now, and another in a month's time, otherwise you might end up with a glut.
They'll be sprouting within a matter of days!
Thin them if they need it, to leave 1-2in between plants.
Flea beetles can be a problem in April/May - nibbling little holes in your leaves, but the roots are still perfectly edible.
Your radishes should be ready 4-6 weeks from sowing. Work your way along the row, pulling the bigger ones and firming back the soil.
The bigger you let them grow, the hotter they'll taste!
