Direct sow radish seeds from March to September outdoors. Grow radish in a well prepared fertile, moist, free draining seedbed in full sun or semi shade. Sow radish seeds thinly at a depth of 1cm (1/2”) in drills 15cm (6") apart. When large enough to handle, thin out the seedlings within each row to 2.5cm (1”) apart. Regular sowings made at 4 week intervals will ensure a steady supply of radishes throughout the season. Radish plants are quick growing and can be used for intercropping between other slower growing vegetables such as parsnips. Where space is limited, growing radish in patio containers will also produce a worthwhile crop. Keep watered to prevent bolting (running to seed) and a harvest of overly hot, pithy roots.
