Radishes grow quickly, often producing radishes in 22 to 30 days from the date of planting, making them the ideal vegetables for young gardeners eager to see the fruit of their labor. These tiny red globes add distinct flavor and bright color to salads or as a garnish for side dishes. Eaten right from the garden they provide a crisp snack bursting with spicy flavor.
Prepare a planting area in full sun by tilling to a depth of 6 to 8 inches. Remove any rocks, roots or other debris and rake smooth.
Test the soil to determine the needs of your specific soil. You can purchase an inexpensive soil test kit at your hardware ir garden store. Follow the recommendations for amending and adjust pH to 6.5.
Add a 2 to 3 inch layer of well-rotted manure or compost and work in well with the existing soil to improve texture, aeration and drainage.
Plant seeds in spring as soon as the soil can be worked. Wet soggy soil must dry before planting. Squeeze a handful of soil into a ball. If the soil holds its shape, but crumbles when poked with the finder it is ready for planting. Soil that remains in a ball requires more drying.
Sow seeds to a depth of ¼ to 1/2 inch spaced 1 inch apart. Water thoroughly and keep the soil moist until seedlings emerge in a few days to a week, depending on the weather conditions and temperature of the soil.
Remove weeds as they appear, using care not to uproot radishes.
Harvest when the bulb of the radish is plump and round. Radishes mature quickly and become tough and spicy-hot within a few days if not harvested early.
