Lyle Becker is greenhouse coordinator at Ace Hardware, 2404 Broadway, (605) 260-2813. He shares tips for growing radishes.
“This is a good crop if you are just learning to garden,” he said. “You will receive a quick result. You should have radishes about 25 to 30 days after planting.”
• For soil preparation, I try to till the area in the fall so I am ready as early as possible in the spring. Then all you have to do at the beginning of the season is rake and plant.
• Radishes like cool weather so I try to start planting by the end of March or the first of April.
• Don’t fertilize radishes. Too much fertilizer and you will get all tops and no radishes.
• For direct seed planting in rows, you will need to space rows about a foot apart. Space your seeds two to three inches apart. Use the seed sparingly so you don’t have to do a lot of extra thinning later. Use two seeds in each planting hole. Later thin to the healthiest plant per hole. An average packet of seed should plant about 50 to 60 feet of radish plants.
• Plant radishes every two weeks until the 1st of June. (With slow soil warm up this spring, try a few now.) Then plant again Aug. 15 until Sept. 15. Keep the plants well-watered so they grow quickly.
• Always plant different varieties and try to include something new each year. Harvest when the radish is about the size of a quarter.
