Radish is a member of the Raphanus family. Its botanical name is Raphanus sativus. The scientific name epithet sativus means 'having been cultivated'.
Radishes are extremely variable. The most common varieties are grown for their edible roots, which can range in diameter from 1 inch (2.5 cm) to 8 (20 cm) inches, and in shape from globes to carrot shapes. Less common varieties have no edible roots, and are grown for leaves, seed pods or seeds.Radish grows as an annual and is an edible vegetable. Being an annual plant, it tends to grow best over the course of a single year. Normally growing to a mature height of 15.0 cm (5.85 inches), Radish grows with a shrubby habit. Some varieties of Radish you may like to consider growing are: Cherry Belle, French Breakfast, Sparkler, Watermelon, and Easter egg.
France is believed to be where Radish originates from.
Radish is normally fairly low maintenance and quite easy to grow, as long as a level of basic care is provided throughout the year. Being aware of the basic soil, sun and water preferences will result in a happier and healthier plant.

Radishes are generally free from pests, although some are troubled by flea beetles. They can be planted and allowed to go to seed near squash plants to deter squash bugs.
The secret to good radishes is plenty of even moisture. Supply sufficient water to plants without creating waterlogged soil. If allowed to dry out, radishes taste hot.
Plant in cool weather to avoid hot radishes.
Replant small crops every 2 to 3 weeks. Thin shortly after they emerge because they mature so quickly.
Radishes are very quick and easy to germinate, and no special attention is generally needed. If you are starting them extra early in spring, a warm water soak for 1-2 hours before planting will be helpful, but is not necessary.
Germination Time (Days)
29 days at 41° F
11 days at 50° F
6 days at 59° F
4 days at 68° F
4 days at 77° F or higher
By our calculations*, you should look at sowing Radish about 28 days before your last frost date .
Radishes do not respond well to transplanting. Root and leaf varieties should be directly sown in stone-free soil in early spring to early summer, and again in late summer for fall crop. Pod varieties should be directly sown in warm weather. Make successive sowing every 2-3 weeks.
Pull the plants when the seed pods turn yellow. Hang them in a dry place to cure. 1

Planted these late in the spring for an early June harvest. The radishes grew fantastic! They were quite spicy though, too spicy for us, going to pickle them and try again in the Fall/cool weather!
