The under-explored vegetable: Daikon Radish

Daikon Radish: There are over a hundred varieties of daikon radishes, but to most people in America this root is a vegetable of mystery.  Daikon radishes are popular in Japan, Taiwan, Korea and China, so in the states it is often found in Asian grocery stores, ethnic specialty stores or growers markets where large Asian-American populations occur.  But, luckily for us, most of Ashland’s grocery stores carry daikon radish year round   

Daikon radish is a member of Brassica family; a cool weather vegetable. This tuber forms a large cylindrical tap root 12-20 inches long and 2-4 inches in diameter. Its root pushes deep in the soil like a giant carrot, but leaves 2 to 6 inches protruding above the ground. Its skin is pale green or all white, similar to a turnip.  The flavor is tangy with a crisp juicy texture, and depending on the variety, it can be a mild to fiery hot, like a horseradish.  Its mildness or hotness also depends on growing conditions and the amount of water it receives during the growing season.

Daikon radish origins trace back to the Mediterranean and Black Sea coasts. It found its way to Japan approximately 1,300 years ago where it became popular nationwide in the Edo period (1603-1868). Many varieties of the daikon radishes are near extinction due to the lack of commercial value, but a few specialty farmers, especially in Japan, are growing heirloom varieties for chefs and these prized radishes can fetch a high price.  But the most cultivated daikon radish for the world market is the Aokubi Daikon, which is a milder sweeter variety.  Japan produces 90% of the worlds Daikon radish crop, and they consume most of this crop as well.

In the United States there is growing interest to use daikon radish as a winter cover crop. Some of this crop is used for consumption, but most of it is plowed under to add nitrogen to the soil.  Purdue University reports that daikon radish as a winter cover crop suppresses weeds in fall and winter, helps break up compacted soil, and because its contains a lot of water, it decomposes in a short period of time providing a flush of nitrogen for early spring crops.

Daikon radish can be consumed raw, cooked, or pickled. You can shred it to use in salads for a crisp crunchy texture and a peppery bite. You can add thin slices into miso soup, or braise it in thick chunks for stews. Boiling daikon chunks in water for 30 minutes then adding to a recipe allows the radish to absorb the flavors of the dish. Amazingly, this root holds its shape and texture after an hour of cooking.   The tops are edible too; sauté in oil until wilted then add seasonings.  Daikon Radish seeds are readily available because daikon radish mico-greens are popular.  

To start your sprouts, soak seeds in a bowl of cool water for 6 hours, or overnight, making sure seeds are submersed. This softens the seed coat and promotes germination. Grow as mico-greens, or sow directly into the garden for mature vegetables.  OSU Department of Horticulture states in Oregon daikon radishes require a full growing season to reach maturity and for the best root quality and development irrigate well to maintain uniform, vigorous growth.    USDA Hardiness Zone 2-11

Winter Interest: Crabapples Part II

Crabapple cultivars are versatile; they are available in various sizes, flower colors, fruit colors and fruit sizes.  Flower colors vary from white, light pink, deep pink and magenta, these blossoms are showy, often fragrant, and they attract pollinators. Crabapple fruit differ in sizes from ¼-inch to 1 ½-inch, and ripening times range from July through November. For fruit colors you can chose a tree that produces bright red, deep red, maroon, rose red, pink, deep pink, rose pink, golden orange or yellow-green fruit.  Crabapple apples provide an abundant food source for birds during the winter, and they provide winter interest in your landscape. Look for trees labeled with “persistent” fruit, meaning fruits stay on the tree extending garden interest and food for birds.

Crabapples are hardy in Zones 4-8.
Sun Exposure:  Full Sun 6+ hours, Part Sun 4-6 hours, Full Shade up to 4 hours. Select disease resistance varieties best for your growing area. Selecting disease resistance varieties should be a 1st priority for successful growing.

Crabapples Add Winter Interest

Crabapples are an excellent choice for creating winter interest in a landscape and their small fruits are a desirable food source for birds. Crabapples have a reputation of being messy, but if you purchase trees with “persistent” fruit, then the fruits stays on the tree longer, making less of a mess on the ground and leaving more fruit on the tree for birds. Persistent fruits also provide longer winter interest with red, pink, orange or yellow fruits hanging on trees.

Crabapple blossoms come in white, light pink, deep pink and rose-colored, which attracts butterflies and bees in the spring.  Some varieties have fragrant flowers and some have purple foliage.  Crabapples come in various sizes to accommodate small, medium or large yards.  In this first posting I am listing three dwarf varieties for small spaces and ones with excellent to good disease resistance; there are many more.

Just say NO to Fall Clean Up

While diseased plants and leaves should be removed from your flowerbeds,  leaving plant debris, seed heads, plant stalks, and leaf litter provides much needed winter shelters and food for beneficial insects and birds. 

Forging urban birds like juncos, sparrows and chickadees need your plant’s seeds for food, and beneficial insects, like butterflies and moths, winter over on flower and ornamental grass stalks. So, by cutting and cleaning out flowerbed debris you are doing more harm than good by disrupting your garden’s natural habitat.

Rethink fall clean up, resist the urge to remove all the debris, keep it until spring because the wildlife depends on it! It also provides mulch to protect plants during cold weather.

Today in the Garden

I found a surprise in my garden today. This white flower appears to be a begonia, but I don’t recall planting it. Friends and neighbors do give me plants which often need help, so perhaps this one came to me as a sad root in a pot without an identity. It’s a lovely surprise on this smokey October day. I really like the happy ball-shaped yellow centers. I felt like it was a gift from the garden fairies when I saw it. ~Carlotta Lucas, AGC Member
