Daikon radishes require full season to reach maturity, and 12-15 inches of water under western Oregon conditions. For best root quality, irrigate to maintain uniform, vigorous growth. Soil type does not affect the amount of total water needed, but does dictate frequency of water application. Lighter soils need more frequent water applications, but less water applied per application. Three or four crops may be obtained per season on the same ground.
All harvesting is done by hand.
Red radishes are pulled and tied in bunches. The bunches are washed and should be cooled immediately after harvest for best shelf life. About 90 percent are currently packed in 4-dozen cartons. The 2-dozen cartons are mostly used for shipments to California. Radishes should be kept moist and cool at all times to prevent dehydration.
