Do you like radishes? I often plant them in my garden and then use them in salads. Radishes grow easily from seeds and are a fun project for young gardeners. The best radishes are those that are harvested at the right time. Plant them in cool weather and provide moisture.
Spring varieties mature fast and it's best when you check often by pushing away a bit of soil and checking on the growing bulb. They should not be too spicy or too tough tasting.
