Winter radishes are distinct from their smaller, more colorful spring varieties, both in terms of size and taste.These hearty types are grown over a longer period, allowing them to reach remarkable dimensions. While they can certainly be eaten raw, there is a wide array of culinary uses for them—consider incorporating them into robust soups, zesty stir-fries, or roasting alongside other root vegetables.

The first winter radish I discovered was the ‘Black Spanish Round’ (Raphanus sativus).This classic variety grows into large spheres reminiscent of tennis balls and boasts a rough black skin that conceals crisp white flesh inside. I was intrigued to find out that the mooli—or daikon—also falls under the category of winter radishes while enjoying it pickled in a Vietnamese banh mi or fermented into kimchi. With its elongated conical shape and mild flavor paired with an enjoyable crunch, it’s unfortunate that my heavy clay soil makes cultivating them quite difficult. The watermelon radish remains my ultimate gardening goal; despite several attempts over recent seasons, I have yet to successfully grow this gorgeous variety. Its true allure is revealed when sliced open to unveil its vibrant fuchsia interior—a sight truly worth striving for! Perhaps my late-summer exhaustion has impeded my success with what should be an easy crop.

Sowing winter radish seeds directly into well-draining soil is advisable as they do not adapt well to being transplanted after germination. However, I’ve had success starting spring varieties in module trays; thus I believe similar techniques coudl work for these larger types if transplanted promptly after germination. While I often sow spring radishes in clusters due to their ability to thrive together, these winter varieties necessitate careful thinning according to seed packet instructions because of their size requirements. Choose a sunny spot and ensure your young plants receive sufficient water while protecting them from late summer flea beetles using insect-proof mesh covers. Like all root crops, the soil must be conducive as they will push downwards as they mature.

while some experts claim that year-round cultivation of these varieties is possible, attempting sowing during spring may cause your plants to bolt prematurely and flower before developing substantial roots.

You can anticipate harvesting winter radishes within eight weeks under ideal conditions; moreover, if weather allows it, you can leave them in the ground until you’re ready for use. They also store exceptionally well when harvested before frost arrives—just remember to trim off any edible leaves beforehand and plan on consuming those prior to storing your winter harvest in a cool dry location.
