Radish - Watermelon - Raphanus sativus Hardy Annual Heirloom. A uniquely colored and very large radish, the watermelon radish grows to about 4" causing it often to be mistaken for a turnip. It has green shoulders that fade to brilliant white on the exterior and bright pink inner flesh. The white part is hotter and the interior is peppery-sweet. Watermelon radishes are an extremely mild radish. The Watermelon Radish is a type of daikon radish that is called Shinrimei in its native land of China.

Direct sow Watermelon Radish into a fine, loose seedbed during a suitable cool-season window. Keep the shallow root zone evenly moist as seedlings emerge, then thin to prevent crowding and misshapen roots. Radishes can change texture as they remain in the ground, so begin checking root shoulders near the early end of the maturity range. Harvest at the diameter and crispness you prefer, and date succession sowings separately.
Soil and Water: Radishes prefer well-drained soil with plenty of added organic matter.
Before sowing Watermelon Radish, review the packet alongside the current product details and note any range in temperature, germination, or maturity. Ranges reflect biological and seasonal variation rather than a fixed promise. Label each planting with its date and location, then compare emergence, growth, and harvest with local weather. This record is useful for succession plantings and for deciding whether the crop fits better into an earlier or later seasonal window.
