Radish is a cool season crop and seeds can be sown directly in the garden in early Spring as soon as the soil can be worked. Soil temperature (not air temperature) should be between 10-16° C (50-60°F) . Space seeds and plant to the depth indicated below. Press seeds into the soil to ensure good contact and cover with 2.5 cm (1") of soil. After planting, water seeds with a gentle mist or shower. It is critical to keep the soil consistently moist, but not soggy during germination. When your seedlings reach a height of a few centimetres (inches) and have developed 2 or 3 pairs of leaves, it is important to thin them out, according to the plant spacing indicated below. Crowded radishes do not grow well, and you’ll end up getting small inedible roots. Do not allow the soil to become dry, as young plants have underdeveloped roots and can quickly dehydrate, particularly in windy conditions. Weed often as weeds can quickly crowd out radishes. Radish grows quickly and more seeds can be succession planted every 10 days until the temperature exceeds 21°C (70°F). Once the temperature rises, radish tends to bolt. Planting can resume when the temperature turns cooler at the end of Summer and early Fall.

Suggestions
Growing Suggestions:
- Consistent moisture is key. Do not let the soil dry out which can result in poor flavor and a tough texture. Soil that's too wet can cause the roots to split and rot.
- Do not leave radishes in the ground past their maturity; they can go from crisp and crunchy to woody and excessively spicy within a matter of days. Follow the seed packet for the number of days to maturity.
- Hot weather can cause the plants to bolt (a flower forms and it goes to seed) and decline in quality and bulbs will stop forming. They can get tough and woody or spongy with hollow centers.
