Why don't my radishes mature?
I have planted radishes in my garden several times from April through August and they never mature. The cultivar is "Rover" purchased at Johnny's Selected Seeds. It forms leaves and a root but no bulbous radish. I have tried shade, part shade and sun. I don't see any evidence of pests (leaves look good) and the plant looks otherwise healthy. The soil has a reasonable humus content and other veggies like turnips, lettuce, beans, beets do fine. What could do this?

When soil temperatures are high, nitrogen appears readily available for top growth development and not root growth. Try planting them earlier in the spring or later in the fall. You still have time for a fall planting.
