Radishes have a lovely spicy flavor and a fabulous crunch that is totally unexpected and very different from most veggies. I remember as a child my dad snacking away on them as if they were candy. One day I grabbed one out of his hand to try and pretty much gasped at the unexpected flavor. "Yuck!" I screamed. But today I have grown to love these little root veggies.
Now is a great time to plant them down south. You should make sure that the soil is about 65 degrees before planting them. Use your fresh compost to give these guys some really nice soil and take care to plant them where the sun shines.
