If you’ve considered starting a vegetable garden but are intimidated by the idea, this time of year is a great time to give radishes a try. Radishes are a cool season crop and will grow well in the mild winter climate of North Florida. The ease of growing this cool season vegetable also make them an ideal starter plant to get kids interested in gardening.

Radishes germinate with soil temperatures of 45-85⁰F and grow well when temperatures average 50-65⁰F, so October to November is a good time to plant in the fall. They develop quickly and are ready to harvest in as little as 3-4 weeks, so the quick results keep children interested.

Don’t have a garden area setup yet? No problem, grow radishes in a container! They take up very little space both in width and depth and can be easily grown in a modest sized pot. Radish seeds are small so should be planted very shallow, only cover with about ¼” of soil. Space plants about 6 inches apart and stagger planting dates through the fall and winter so that you can harvest as needed and still have a new crop coming on. For best flavor and texture, harvest when radish roots are ¾ inch diameter or less.

Floridians are lucky, in that they are able to grow many vegetables throughout the winter months. If a fast growing, quick producing vegetable is desired, nothing is faster than a radish. Radishes can develop from seed to mature root in 20-30 days, and can be planted any time between September and March. The cooler months of October to February are even better since radishes do not develop the “hot” flavor when grown in cooler temperatures. There is less risk of that occurring during the cooler months of fall and winter.

Radishes should be direct seeded in the garden at a depth of 0.25 inches. They should be seeded 1 inch apart, with rows 6 inches apart. It is important that they not be crowded since the edible root portion will not form properly unless the plants are given plenty of space. Once plants emerge, thin them to about 3 inches apart.

At planting, plenty or organic matter and fertilizer should be incorporated in the bed. If soil is not well-drained garden in a raised bed. Avoid fertilizing once the seeds have germinated. Make sure to provide uniform irrigation and a weed free environment.

Harvest should take place when the radishes are ready (20-30 days), but fairly young to ensure a mild tasting root.
