Gigante Kohlrabi

seeds

Brassica oleracea (gongylodes group)
(130 days) Open pollinated. These get enormous, regularly exceeding 10" in diameter and 10 lb. Unlike other kohlrabi, this Czechoslovakian heirloom doesn’t get woody even at such a large size. A root cellar staple, Gigante’s crisp white mildly tangy flesh will add zest to your meals while you await the first edible greens of spring. Staffer Emily Skrobis praises Gigante: “It tastes alive in the dead of winter” and reports that her kohlrabi and carrot slaw is always a hit at potlucks. Sow in spring for late fall harvest. Leaves sweeten like a tender kale after a few hard frosts in the fall and stems likewise become as delicious as their broccoli counterparts.

Additional Information

Kohlrabi

About 100-300 seeds/g.
Days to maturity are from seeding date, for transplants, subtract 20 days.

Don’t like kohlrabi? Try harvesting it young. Its texture turns tough, woody and inedible if you wait too long. Use wire hoops and row cover to keep flea beetles out.

Brassicas

Days to maturity are from transplant date.

Culture: Start brassicas indoors March-May for setting out May-July, or direct-seed in May, or in June for fall crop. Minimum germination soil temperature 40°, optimal range 55–85°. Easier grown for the fall because many varieties perform poorly in hot summers. For better stands in dry conditions, sow in trenches and keep irrigated. Wire hoops and row cover should be used at early stages to keep out flea beetles and swede midge.

Note: because of a rule issued by Oregon, we cannot ship brassica packets larger than ½ oz. (14 grams) into the Willamette Valley, except those that have tested negative for Black Leg and Black Rot. Check descriptions for information.

Swede Midge—not as cute as it sounds!

Alert! Heading brassicas in the Northeast are seeing consistent damage from swede midge, a tiny gall midge. Its effects result in a non-heading plant. Wire hoops and row cover at early stages of heading brassica crops are becoming crucial for success. Some research also suggests garlic sprays as a possible organic repellent. Consult your Cooperative Extension resources for further information.
