Question: My radishes are so hot and peppery that we can hardly eat them. What causes that?

Answer: Stress during their time in your garden. Most often, it’s caused by planting too late. When the weather turns hot, so do the radishes. Sometimes folks leave them in the garden too long, and they get overly mature. If you let them get too dry, that can also result in hot radishes. The secrets in growing good radishes are to plant them at the right time (cool weather) and to grow them quickly, so you can harvest them within just 4 to 5 weeks, depending on the variety you’re growing.
