Radish: The Fastest Vegetable to Market
I’ve heard it said there’s no such thing as a vegetable that grows fast, tastes good, and is cheap….well they must not have considered the radish!
If a fast growing, quick producing vegetable is desired, nothing is better 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 ideal if you prefer a mild tasting radish. When grown in the cooler temperatures of fall and winter, radishes tend not to develop that characteristic “hot” flavor.
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 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/or fertilizer should be broadcast on the row. On a per acre basis, 50 pounds of nitrogen and 100 pounds each of phosphorus and potassium should be applied (if soil test indicates the need). 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 mature (20-30 days), but still fairly young to ensure a mild tasting crop.
