Radish

Radishes prefer loose, well-drained soil around pH 6.0-7.0 and grow best in cool weather. A little compost is usually enough fertility; excess nitrogen makes leafy tops rather than good roots, so focus on rapid, evenly watered growth.

Tips

• Sow spring radishes 1/2 inch deep every 7-10 days and thin to 1-2 inches apart.
• Keep soil consistently moist to limit tough, excessively pungent roots.
• Avoid extra nitrogen fertilizer in an already fertile bed.
• Use insect mesh from emergence to discourage flea beetles and root maggot flies.
• Pull roots as soon as they reach the size listed for the variety, before they become pithy.
