According to Florida-Agriculture.com, “Florida is the leading producer of radishes in the United States and harvests over 30 percent of the country’s radish acreage. The bulk of Florida’s radish farms can be found in Orange and Palm Beach counties, where the warm, sunny climate is ideal for growing a wide variety of vegetables. The value of the state’s radish crop is estimated at $30 million a year”.
This is easy for me to believe because radishes are one of the easiest vegetables for Florida gardeners. While this season’s early freezing weather and drought-like conditions put an early end to my Florida Winter Garden, my radishes have been growing like gang busters. Unfortunately unlike tomatoes, green beans and other vegetables, I cannot find much to do with radishes other than use them as salad garnish so I keep some of my radish harvest for myself and usually give the rest away to friends and co-workers who enjoy eating them.
I have seen articles on the internet where it is said that the bright green tops of radishes are also edible, but for me, their pungent flavor is a little too aggressive although some people say it reminds them of arugula.
If you like radishes, now is the last chance to plant them (see Planting Dates for Cool Season Vegetables from Seed for other vegetables you can plant now).
Sowing Radish Seeds:
Sow radish seeds 1/2 inch deep. Space them 1 1/2 to two inches apart in separate rows eight to ten inches apart
Broadcast spreading is also common and easy to do. Prepare a square or rectangular area and spread the seed out across the entire area. Then, lightly sprinkle loose soil over the area.
Thin seedlings to two inches apart in all directions. Radishes do not like to be crowded and will not bulb properly if overcrowded by other radishes or weeds. Weeding is also important to proper bulb growth. Most growers don't give much thought to weeding because of their quick growth, but it is important for proper bulb growth.
Succession planting every two weeks will result in radishes all season long. In Florida radishes do not perform well in high heat and may become corky textured or bolt in hot weather.
Radishes will grow in average soils. Like other vegetables, they will respond to rich, well drained soil. While preparing your garden space, work the soil six inches or more if you are growing the long, cylindrical varieties. Add fertilizer while working the soil. Make sure to remove rocks and stones.
