Superschmelz Kohlrabi

Superschmelz Kohlrabi


70 days. Other giant kohlrabi types tested by Territorial over the years have proven to be woody and throw a high percentage of off-types. Superschmelz is the only giant variety we've tested that grows uniformly large and remains very sweet and tender to the biggest sizes. It produces juicy 8-10 inch bulbs, and the large root system lends itself to dry gardening. Best quality when summer sown for fall harvest.

Brassica oleracea, Gongylodes Group: Once a common vegetable, this curious brassica family crop had fallen into unfortunate obscurity, only recently being rediscovered by many present-day gardeners. Its crisp, mildly sweet bulb has a hint of apple, can be enjoyed raw or cooked, and provides lots of fiber, vitamins C and B6 along with copper, potassium, and manganese.

Days to maturity are calculated from date of direct seeding.

• Kohlrabi performs best in the cool season and can tolerate a wide range of soil types
• For extended harvests, plant every 2-3 weeks
• Mature plants are frost tolerant and cool weather brings out sweet flavor

Direct Sowing
• May and June sowings should be avoided as they result in kohlrabi maturing in the hottest weather, producing dry, woody bulbs
• Sowings can resume from mid-July to mid-August for fall/winter harvest
• Thin when plants have 2 sets of true leaves

• Start seeds 4-6 weeks before anticipated transplant date
• Transplant outside when there are 6-8 true leaves and nighttime temperatures remain above 40°F
• Start May—July for transplanting June—August for a fall crop

Insects & Diseases
Common insects: See Brassica Insect Information below
Disease prevention: 5-7 year crop rotation

Harvest & Storage
• For spring-sown kohlrabi: harvest when less than 2-4 inches in diameter
• Fall-grown kohlrabi is less likely to get woody as it gets larger
• Store at 36°F and 95% relative humidity

Brassica Insect Information
Aphids: Control aphids with ladybugs or a hard spray of water, Neem oil or Pyrethrin. Also, select varieties that mature later in the season when aphid populations decline.
Cabbage worms, loopers, and root maggots: The first sign of cabbage worms will be off-white butterflies fluttering near the plants. They lay their yellowish-colored eggs on the undersides of leaves, which hatch into caterpillars that can cause severe root and head damage. To control light infestations, spray plants with Bacillus thuringiensis (B.t.). For heavy infestations, bait cabbage worms by mixing wheat bran into a B.t. solution. Add 1 tablespoon of molasses. Broadcast the bran mixture around the base of plants. Reapply as necessary. Using Reemay or Summer Insect Barrier can also provide control.
Flea beetles: Flea beetles chew tiny pinholes in leaves. Early control is essential to minimize the damage. Spray infected plants with Pyrethrin. Using floating row covers such as Summer Insect Barrier can also provide control.
Symphylans: In some areas of the US, symphylans (also known as garden centipede) can severely impede the plant growth of many crops. Only 1/4 inch long, white, and very active, they eat the root hairs of developing plants. Using larger transplants helps reduce damage. Contact your local county extension agent if you suspect you have a problem.

I grew this for the first time this summer. I usually grow the standard-sized variety with much success so I thought I'd give this a try! Who wouldn't want a kohlrabi the size of one's head?! I just harvested my first one yesterday (09-26-2012) and after removing the refuse the edible portion weighed 7 pounds! It is tasty and still very tender. All of my other plants, however, are not nearly as large, even though they were all planted at the same time. But I should be able to keep them in the ground a bit longer so we'll see what happens with those.

I grew this Kohlrabi for the first time last season, and was amazed by everything about this vegetable. It grew huge, but was still tender, and very flavorful. I bbqed them with a bit of salt, pepper, and balsamic vinegar at a party, and everyone loved it.
